1 The Wild Mammals of Jujuy Province, Argentina: Systematics and Distribution Los Mamíferos Silvestres de la Provincia de Jujuy, Argentina: Sistemática y Distribución M. Mónica Díaz and Rubén M. Barquez ABSTRACT We present the results of extensive field surveys conducted in Jujuy Province over a 3- year period. Additionally, specimens at several collections were examined and available literature was used to supplement information. Jujuy Province supports 143 species of mammals, represented by 9 didelphimorphs, 10 edentates, 36 bats, 2 primates, 20 carnivores, 1 perissodactyl, 8 artiodactyls, 56 rodents, and 1 lagomorph. One of the species is new to science, 4 are new for Argentina, 2 are new for NW Argentina, and 14 are new for the province. Other species of mammals are here considered as probable for the province based on recent references or records we have yet to confirm; these include 1 xenarthran, 1 bat, 2 artiodactyls, and 3 rodents. Additionally, 2 artiodactyls are probable according to historical records. Four introduced species (3 Muridae and 1 Leporidae) are not included in the checklist of species, and 5 species are excluded from Jujuy Province. Using these data we conducted a biogeographic analysis to determine the degree of similarity among the phytogeographic regions of Jujuy. Key words: Mammals, systematics, distribution, biogeography, natural history, Jujuy, Argentina. RESUMEN En este trabajo se presentan los resultados de muestreos extensivos de campo realizados en la provincia de Jujuy a lo largo de tres años, sumados a la revisión de ejemplares de numerosas colecciones sistemáticas, y a información procedente de la literatura. Hasta el momento la provincia de Jujuy era la menos relevada del noroeste de Argentina, y a pesar de su pequeño tamaño es una de la más diversas de la región respecto a su fauna de mamíferos.

Many naturalists, explorers, and colonizers, have recorded their observations, particularly Emilio Budin, who collected for Oldfield Thomas from The British Museum (London, England). Thomas described a number of new species and subspecies for Argentina and new to science (e.g., Thomas, 1897, 1898, 1913, 1916a, 1916c, 1918, 1919a, 1919b, 1919c, 1920b, 1921a, 1921b, 1921c, 1926a, 1926b). Recent years have seen a number of new studies on argentine mammals (e.g., Yepes, 1929, 1930, 1944; Crespo, 1950, 1958, 1974; Olrog, 1959, 1976, 1979; Mares, 1973; Dalby and Mares, 1974; Massoia, 1976, 1980; Williams and Mares, 1978a, 1978b; Barquez, et al., 1980, 1991, 1993; Olrog and Lucero, 1981; Contreras, 1982; Barquez, 1983, 1987; Ojeda and Mares, 1989; Barquez and Lougheed, 1990; Barquez and Ojeda, 1992; Massoia et al., 1992a, 1992b; Mares et al., 1995, 1996, 1997; Díaz and Barquez, 2002), but reflecting the sheer size of the country and the diversity of habitats, further surveys are needed in many areas that remain poorly known (Pine, 1982). Northwest Argentina has a high diversity of mammals, including 9 orders, 29 families, approximately 100 genera, and 186 species; there are 76 type localities in the area, including 16 in the province of Jujuy (Cabrera, 1958, 1961a, 1961b; Wilson and Reeder, 1993). During the last several years, new genera and species have been described in Argentina, including some from the northwest regions. These include a new species of Cryptonanus from the province of Jujuy (Flores et al. 2000; Díaz et al., 2002; Voss et al. 2005), and new genera and species of sigmodontines and octodontids (Díaz et al., 1999; Mares et al. 2000). Matschie (1894) published one of the first papers concerning the mammals of NW Argentina, including the province of Jujuy. The contributions of Oldfield Thomas also were important at the beginning of the century; he added several species to the fauna of Jujuy, many of them representing species new to science, based largely on specimens collected by E. Budin. Later, some large-scale studies on the mammals of Jujuy, Salta, Tucumán, and Catamarca provinces were published (Mares et al., 1981, 1989, 1996, 1997; Ojeda and Mares, 1989; Barquez et al., 1991; Díaz et al., 1997, 2000; Díaz, 2000; Díaz and Barquez, 2002); in general, however, most of these studies were

3 Díaz and Barquez: Wild Mammals of Jujuy Province, Argentina 419 taxonomically or geographically restricted (Crespo, 1941; Olrog et al., 1976; Olrog, 1979; Cajal, 1985a, 1985b; Barquez and Ojeda, 1992; Heinonen and Bosso, 1994; Iudica, 1995; Capllonch et al., 1997; Cajal and Buenaventura, 1998 ; Perovic, 1998; Barquez et al., 1999; Jayat et al., 1999). Until recently the province of Jujuy has not been thoroughly surveyed, in spite of being one of the most diverse provinces of Argentina with respect to mammalian species richness and taxonomic diversity. The principal objective of this investigation was focused in surveying the as many localities as possible within the province, emphasizing the less well-known areas and those that have never been studied, such as the highlands (Prepuna, Puna, High Andean). Another objective was to resolve taxonomic problems in some groups, such as rodent and marsupials, as well as to confirm the presence of species thought to occur in the province, to compare the faunal composition between phytogeographic areas of the province at species levels. This study has permitted us to publish a field guide for the mammals of Jujuy (Díaz and Barquez, 2002), where the information was reduced and adapted to be used as an identification tool by researchers, students and rangers. Our studies in Jujuy have confirmed the presence of 143 species of mammals, plus 7 that likely occur there or that have records that could not be confirmed, and 2 species that no longer occur there. We have named 1 species new to science (Díaz et al., 2002), and added 14 species to the province, 2 to NW Argentina, and 4 to Argentina (Díaz and Barquez, 1999; Flores et al., 2000; Barquez and Díaz, 2001); we have also elevated 4 subspecies (2 marsupials and 2 rodents) to the species level (Flores et al., 2000); as a result of our studies, the information offered in this paper provides more accurate range limits for these species, and allows us to pursue several biogeographic analysis. In spite of the extensive systematic collections and field surveys, there are still several questions to be answered, particularly concerning the identity of several taxa and their precise distributional limits. STUDY AREA The Province of Jujuy is located in northwestern Argentina, bordered by Bolivia to the north, Chile and Bolivia to the west, and Salta Province to the east and south (Fig. 1). It covers slightly over 53,219 km 2, representing 1.9% of the national territory. The extreme points are, the confluence of the Rivers Mojinete and Grande de San Juan (21 46 S, W) to the north, and the headwaters of the Arroyo de Quisto, at the Cresta de Gallo mountains (24 37 S, W) to the south, and from the a point just north of the Arroyo Ojo de Agua, at the Sierra del Maíz Gordo (24 12 S, W), westward to the Hito in Pampa del Lari (23 41 S, W). In spite of its small area, Jujuy is one of richest provinces in the country in floristic terms. Its tropical location and altitudinal range (500 to 6000 m) result in a multitude of climates and habitats, with consequent variation in vegetation. As a result, the province supports subtropical forests, chacoan forests, mountain forests, xerophytic woodland, high grasslands, and High Andean steppes (Cabrera, 1977), represented by 5 phytogeographic regions (Fig. 1): High Andean, Puna, Prepuna, Yungas, and Chaco. In the Puna of Jujuy (Fig. 2A), the climate, both daily and seasonal, is characterized by its aridity and great thermal range, with precipitation falling almost exclusively in

In winter, the mean temperature is less than -1.0 C, while in the warmest month, December, it is 5.3 C (Cabrera, 1976). Rains decrease from north to south, and are practically nonexistent in the region of the large salt flats (Cabrera, 1976). Defined on the basis of vegetation, Troll (1959) defined 4 subdivisions of the Puna (humid, dry, thorny, and desert Puna). Troll s humid subdivision was considered a different province (the High Andean Province) by Cabrera (1977), because it is located at the highest part of the Andes (>4000 m elev.), and the 3 principal plant communities are associated with elevational ranges; these are the High Summit vegetation, the High Andean grassland, and the High Andean thickets (Ruthsatz and Movia, 1975). According to Cabrera (1976) the argentine Puna (exclusive of the High Andean Province) can be climatically divided in 2 zones: to the east is the humid puna, which includes the thorny Puna and the dry Puna of Troll (1959); and to the southwest is the dry puna, corresponding to Troll s desert Puna. However, Vervoorst (1982) recognizes Troll s authority including his 4 divisions for the Puna. In the Prepuna (Fig. 2B) most vegetative growth occurs near ravines and dry slopes, and are dominated by columnar cacti (Trichocereus) and terrestrial bromeliads, ringshaped or in cushions. In the arid zones, an ecotone with the Puna can be observed, as in the Quebrada de Humahuaca (Vervoorst, 1982). The climate is dry and warm, and

Climatic data are scarce, but at Humahuaca the mean temperature is 10.4 C and the annual precipitation is 175 mm; comparable metrics at Tumbaya indicate 3.6 C and 179 mm, respectively (Cabrera, 1976). The Chaco (Fig. 2C) is located at the eastern portion of the province and contains 2 districts; the Occidental District, dominated by Schinopsis lorentzii, and the Serrano District, characterized by the quebracho trees (Schinopsis haenkeana) (Morello and Adámoli, 1968; Ragonese and Castiglione, 1970; Cabrera and Willink, 1973; Vervoorst, 1982). The region is mainly a flat plain with elevations generally no higher than 300 m, but reaching 1800 m in the Serrano District. The Occidental District has a marked continental climate, with annual precipitations between 500 and 800 mm. The Chaco has been greatly impacted by uncontrolled livestock and forest exploitation (Morello and Saravia Toledo, 1959). The Yungas (Fig. 2D) occur along the western slopes of the mountains in the eastern portion of the province. There are different opinions with respect to the units or divisions that constitute the Yungas (Meyer, 1963; Brown, 1995; Morales et al., 1995; Prado, 1995), but we follow Cabrera (1976) and Cabrera and Willink (1973). The Yungas is limited to the northeast by the Chaco, and to the west with Prepuna or Puna (Cabrera, 1976). The principal vegetation is cloud-forest, rich in laurels (Lauraceae) and myrtles (Myrtaceae). Above the cloud-forests are deciduous woodlands of Alnus acuminata, forests of Podocarpus parlatorei (pino del cerro), and grasslands (Cabrera and Willink, 1973). The climate is warm and humid; precipitation occurs mainly in summer, and

6 422 University of California Publications in Zoology winters are characterized by occasional frost. Annual precipitation reaches 2500 mm and even more in some places. Differences in latitude, altitude, relief, and exposure result in considerable variation among localities that are relatively close to each other (Cabrera, 1976). MATERIALS AND METHODS The province of Jujuy was extensively sampled from January 1995 through March We personally sampled about 220 of the localities given in Appendix I and captured 806 specimens (529 collected and 277 released) belonging to 61 species in 12 families. Additionally, we have examined specimens at several collections (see below), and loans of specimens were obtained from various museums. Some private collections were also examined. These observations and records were used to supplement information available in the literature. Collection and Preparation of Specimens. Small terrestrial mammals were captured with Sherman, Victor, and Museum Special Traps; the bats were collected with mist nets. Large mammals were recorded by direct observation, observation of tracks, signs of activity, photographic traps, and captures with leg traps. Morphometric data were recorded for all captured specimens (Díaz et al., 1998), as well as weight, sex, reproductive condition, presence and identity of ectoparasites, and molting status. Some specimens were prepared as standard skins, skulls, and skeletons, or preserved in alcohol, and deposited at the Colección Mamíferos Lillo (CML) or Programa de Investigaciones de Biodiversidad Argentina (PIDBA), both located in the Faculty of Natural Sciences and Miguel Lillo Institute, National University of Tucumán, Tucumán, Argentina, and at the Sam Noble Oklahoma Museum of Natural History, as unaccessioned materials labeled as ARG (Catalogue of specimens from Argentina). Specimens examined that have not been accessioned into an Institutional Collection or Museum are indicated with the initials of the collectors as follows: JPJ, Jorge Pablo Jayat; MMD, M. Mónica Díaz, and RMB, Rubén Marcos Barquez. Specimens examined at systematic collections are indicated with the following acronyms: AMNH, American Museum of Natural History, New York, New York, United States; BMNH, British Museum (Natural History), London, England; CM, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, United States; CEM, Colección Elio Massoia, Buenos Aires, Argentina; CML, Colección Mamíferos Lillo, Tucumán, Argentina; CR, Colección Rusconi, Tucumán, Argentina; FMNH, Field Museum of Natural History, Chicago, Illinois, United States; IADIZA, Instituto Argentino de Investigaciones de Zonas Áridas, Mendoza, Argentina; SNOMNH, Sam Noble Oklahoma Museum of Natural History, University of Oklahoma, Norman, Oklahoma, United States; MACN, Museo Argentino de Ciencias Naturales Bernardino Rivadavia, Buenos Aires, Argentina; MCNS, Museo de Ciencias Naturales de Salta, Salta, Argentina; MLP, Museo de La Plata, La Plata, Argentina. Examination of Specimens. A total of 2994 specimens were examined, comprising 180 didelphimorphs, 64 edentates, 695 bats, 4 primates, 100 carnivores, 1 perissodactyl, 37 artiodactyls, 1901 rodents, and 12 lagomorphs. With the purpose of identifying the species, the external morphology and both

7 Díaz and Barquez: Wild Mammals of Jujuy Province, Argentina 423 external and cranial morphometrics were compared with type specimens or with original descriptions, and with published revisions (e.g., Pearson, 1958; Hershkovitz, 1962; Myers, 1989; Myers et al., 1990; Barquez et al., 1993, 1999; Braun, 1993; Steppan, 1993, 1995). Localities and Maps. A total of 601 localities were recorded (Appendix 1), of which 42 were not located, and about 300 were located with maps of the Instituto Geográfico Militar, the department of the Dirección Provincial de Hidráulica, the Automóvil Club Argentino, and from Keegan and Keegan (1993). We have also used the following maps of the Instituto Geográfico Militar (year of publication): Chart 2363, Tartagal (1957); Chart , La Quiaca (1957); Chart 2563, Monte Quemado (1957); Chart 2566, Salta (1960), all at scale 1:500,000. Some localities were not found with these maps, because literature citations were not precise or there was insufficient data. In the appendix, all localities were ordered alphabetically, with provincial departments indicated between parentheses. Geographic coordinates for localities sampled by us were obtained with Geographic Positioning System (GPS) and those for specimens not collected personally were determined with the help of the references indicated above. The following localities were erroneously reported by E. Budin as coming from the Sierra de Zenta: La Laguna, Sierra de Zenta, 4500 m; Sierra de Zenta, 4000 m; Sierra de Zenta, 4500 m, E de Maimará; and Sierra de Zenta; all with voucher specimens deposited at the BMNH, MACN, CML, and CR. Budin s original notes are deposited at the CML, however, and these, along with information in Budin (1931), allowed us to Figure 3. Campo Laguna (a Type Locality; mentioned either as La Laguna, Cerro Lagunita, Cerro de Lagunita, Cerro de la Lagunita, or Lagunita). This site is located in Sierras de Tilcara, and O. Thomas referred it as to Sierras de Zenta. Photograph taken 16 June 1997 by D. A. Flores.

Photo of Emilio Budin in his campsite at Campo Laguna on February Vicuñas hunted by him can be seen on the ground. confirm the exact location of these localities, which in fact must be located in Sierra de Tilcara. The place is known by the local residents as Lagunita, or Campo Laguna (Figs. 3, 4), as mentioned in some of Thomas publications (e.g., Thomas, 1913). The locality is in the Sierras de Tilcara, in the mountains E of Tilcara, approximately 70 km S to the locality indicated by Thomas, and in a different mountain chain. Consequently, the type locality must be changed to the location given here. BIOGEOGRAPHICAL ANALYSIS To evaluate biogeographic patterns among phytogeographic areas we compared the species, genera, and families shared between these areas using similarity indices. Faunal similarity between phytogeographical areas was estimated with simple presence/ absence data for species, genera, and families, to analyze the degree of interrelation among regions at different taxonomic levels. We applied both Jaccard s Coefficient (J) (Jaccard, 1908; Sneath, 1957) and the Simple Matching Coefficient (S SM ) (Sokal and Michener, 1958). Jaccard s Coefficient was calculated with the formula: J= a/(a+u) where a is the number of shared species and u is the number unshared species between the phytogeographic areas. This metric does not incorporate absences shared by 2 areas. The Simple Matching Coefficient was calculated as: S SM = m/(m+u) = m/n where m corresponds to the sum of the shared presences (e.g., a) and the number of shared absences (species known for the area but not sharing the phytogeographic regions under comparison), and u is the sum of the unshared species. Thus, this metric does consider shared absences in assessing overall similarity. Both indices range from

9 Díaz and Barquez: Wild Mammals of Jujuy Province, Argentina (minimum similarity) to 1 (maximum similarity). Phytogeographic regions were grouped using the unweighted pair-group arithmetic averaging cluster algorithm (UPGMA) based on similarity values, and expressed in a dendrogram. Cophenetic correlation coefficients between the resultant phenogram and the original similarity matrix estimate the degree to which the relationships suggested by clustering are representative of the actual relation among elements in the original similarity matrix (Sokal and Rohlf, 1962). Generally the values oscillated between 0.6 and 0.9, the values greater than 0.8 indicate a good representation of the matrix of similarity for the dendrogram (Sneath and Sokal, 1973). A consensus between S SM and J was performed to indicate the relationships common to both analyses. Phenetic analyses were performed using NTSYS-pc (Rohlf, 1993). SPECIES ACCOUNTS In this section we report on all species known to occur in Jujuy Province, based either on published literature (with confirmed identity) or our observations. Accounts include scientific name, author, literature citation, and broader distribution in Argentina. Taxonomic arrangement follows Wilson and Reeder (1993) and McKenna and Bell (1997) with some exceptions indicated under comments for each species. The distribution in Jujuy is based on the Specimens Examined and Additional Records; the latter includes records from the literature, interviews with local residents, and personal observations. Unless noted otherwise all specimen localities are from Jujuy Province. Under the Comments section we summarize available information about natural history and taxonomy, incorporating unpublished data obtained during this study, especially pertaining to reproduction, molting, habitat preferences, and feeding habits, among others.

Díaz, personal observation); Río Blanco (Yepes, 1944). Comments.--Records of this species in Jujuy correspond to the Yungas, Chaco, and Prepuna. Several specimens were collected alongside roads. Although Didelphis albiventris is more common in rural regions, 1 specimen was captured in a pristine dense forest at Las Capillas. Heinonen and Bosso (1994) reported this species from Mesada de las Colmenas, Abra de Cañas and from Duraznillar, 2 localities that are included in Cerro Calilegua as mentioned by Olrog (1979). We have recorded a female with developed mammae in February and young specimens in March and July. Genus Cryptonanus Recently described by Voss et al. (2005), this genus was included in northwestern Argentina, in the provinces of Jujuy and Salta, by Flores et al. (2000, as Gracilinanus). It is apparently uncommon or difficult to capture, and records are scarce. Flores et al. (2000) cited 1 species for Jujuy, Cryptonanus chacoensis (as Gracilinanus agilis chacoensis) and Díaz et al. (2002) described Cryptonanus ignitus (as Gracilinanus ignitus). Cryptonanus chacoensis (Tate, 1931) Agile Gracile Mouse Opossum Marmosa agilis chacoensis Tate, American Museum Novitates 493:10. Distribution in Argentina.--This species is found in Corrientes, Chaco, Formosa, Misiones, Entre Ríos, Buenos Aires, Jujuy, and Salta provinces (Massoia and Fornes, 1972; Contreras, 1982, 1984; Flores et al., 2000; Voss et al., 2005). Specimens Examined (3).--Ingenio La Esperanza, 1 (CEM 4691); Santa Bárbara, 2 (AMNH , ). Comments.--This species was previously considered as a subspecies of Gracilinanus agilis, which is now restricted to Brazil, Peru, and probably Paraguay. The records from Jujuy correspond to the Yungas and Chaco.

11 Díaz and Barquez: Wild Mammals of Jujuy Province, Argentina 427 Distribution in Argentina.--Known only from the type locality in Yuto, Jujuy Province. Specimens Examined (1).--Yuto, 1 (AMNH , holotype). Comments.--Nothing is known about the natural history of this species. It was described based on a single specimen deposited at AMNH, collected by F. Contino in 1962, when the province of Jujuy was less disturbed by agricultural development. The holotype is the only specimen known for this species.

Deterville, Paris, 24:19. Distribution in Argentina.--It is found Jujuy, Salta, Formosa, Chaco, Tucumán, Misiones, Corrientes, Entre Ríos, Córdoba, Santa Fe, Buenos Aires, La Pampa, and Mendoza provinces (Flores, 2003). Specimens Examined (4).--Abra de Cañas, El Monolito, 1 (CML 1759); El Duraznal, Santa Bárbara, 1800 m, 2 (CML 1596, 1597); Jujuy, 1 (MACN no number). Additional Records.--Abra de Cañas, 1700 m (Olrog, 1976); Aguas Negras, 600 m (Heinonen and Bosso, 1994); Arroyo Sauzalito (R. M. Barquez, personal observation); Cerro Calilegua (Olrog, 1979); Cerro Santa Bárbara, 1800 m (Olrog, 1976); Parque Nacional Calilegua (Heinonen Fortabat and Chébez, 1997). Comments.--Cabrera (1958) considered 2 subspecies to be present in Argentina, L. c. crassicaudata and L. c. paranalis; the former occurs in Misiones and Formosa provinces, and the latter in Corrientes, Santa Fe, Buenos Aires, west to La Rioja and San Juan provinces. He did not mentioned specimens from northwestern Argentina, in spite of having records being reported since the beginning of the 19th century. According to Massoia (1973) the specimens cited from northwestern Argentina may be not assigned with certainty to any of the known argentine subspecies, but he indicated that they were more similar to L. c. crassicaudata. This taxon is in need of a detailed revision to determine if the different geographical populations should be recognized as subspecies or species; the populations from northwestern Argentina are smaller and darker than those from southern and eastern Argentina (D. A. Flores, personal communication 1995). Heinonen and Bosso (1994) attributed the localities Abra de Cañas and Mesada de las Colmenas to Olrog (1979); however, although Abra de Cañas was noted by Olrog in 1976, Mesada de las Colmenas is not indicated by him in any of his publications. The record by Olrog (1976) for Cerro Santa Bárbara probably corresponds to specimens at the CML from El Duraznal. Records of L. crassicaudata are scarce in Jujuy Province and

12 428 University of California Publications in Zoology all are from the Yungas. A specimen has been observed attacking individuals of Didelphis albiventris in the water while swimming (D. A. Flores, personal communication). Genus Micoureus Micoureus constantiae (Thomas, 1904) Pale-bellied Woolly Mouse Opossum Marmosa constantiae Thomas, Proceedings of the Zoological Society of London, 2:243. Distribution in Argentina.--Northwestern Argentina, in Jujuy, Salta, and Tucumán provinces (Cabrera, 1958; Olrog and Lucero, 1981; Mares et al., 1989; Redford and Eisenberg, 1992; Flores and Díaz, 2002). Specimens Examined (8).--Aguas Negras, 5 (2 CML 2921, 5688; 3 MACN 19425, 19426, 19427); Caimancito, 1 (MACN 30297); Calilegua, 1 (CEM 4886); Río San Francisco, altura de Yuto, 500 m, 1 (BMNH holotype of Marmosa budini). Additional Records.--Aguas Negras, Camping, Parque Nacional Calilegua (M. M. Díaz, personal observation); Mesada de las Colmenas, 1150 m (Heinonen and Bosso, 1994). Comments.--Aguas Negras is the correct locality for the specimen at the CML, cited by Heinonen and Bosso (1994) for Caimancito. All records of Jujuy are from a National Park (Parque Nacional Calilegua) in the Yungas. In specimens collected at Aguas Negras, Camping, Parque Nacional Calilegua, we have observed an aggressive behavior, and a great ability to climb the trees. At the same locality a female captured in June had mammae pigmented strongly ochraceous. The subspecies from Jujuy is M. c. budini (Thomas, 1919), whose type locality is in the province. Genus Thylamys Four species of Thylamys are known from Jujuy: T. cinderella, T. sponsorius, T. pallidior, and Thylamys sp. According to Palma (1994, 1995) and Palma and Yates (1998) the specimens cited as T. elegans from Argentina are T. venustus whereas T. elegans is restricted to Chile. According to Flores et al. (2000), not all the specimens from northwestern Argentina correspond to T. venustus. When specimens from northwestern Argentina were compared, we found characters that allow the recognition of the subspecies described by Thomas for this region, Marmosa elegans sponsoria, from Jujuy and M. e. cinderella, from Tucumán. Cabrera (1958) considered these 2 subspecies as synonyms, and Gardner (1993) included them within T. elegans. Tate (1933), in spite of showing sympatry between T. cinderella and T. sponsorius, considered the 2 taxa as subspecies of T. venustus. However, in his list of specimens examined, some individuals were listed for both taxa. For example, he cited León, and Carmencito (=Caimancito) for T. venusta cinderella and also for T. v. sponsorius, but in both cases referenced the same specimen (Flores et al., 2000). Two groups, differing in cranial characters, body size, and a tendency to inhabit different habitats, can be recognized. Based on this information, T. sponsorius and T.

13 Díaz and Barquez: Wild Mammals of Jujuy Province, Argentina 429 cinderella are considered to be valid species (Flores et al., 2000). It is possible that these 2 taxa can live in sympatry in some places because some collecting localities are in close proximity. Actual records of T. pusillus for Jujuy Province were not found. Currently the records in the literature (Olrog and Lucero, 1981; Honacki et al., 1982; Redford and Eisenberg, 1992) correspond to T. pallidior, which is the typical form of the Puna and is considered by some authors as a subspecies of T. pusillus (Cabrera, 1958; Olrog, 1979). Thylamys pusillus inhabits the Chaco, which is a small and extremely disturbed area in Jujuy Province.

Comments.--Records are known mainly from the Chacoan vegetation. Some localities are in Yungas or transitional forests, but always near the Chaco or arid areas, where they may be found in sympatry with T. sponsorius (Flores et al., 2000). On a specimen label at the BMNH ( ), E. Budin wrote that rodents in his traps were eaten by this marsupial. According to information on the original label, the holotype was captured by hand (BMNH ). A lactating female with open vagina was captured in February. Juveniles were collected in February and May, and subadults in May, July, August, September, and October.

Additional Records.--Casabindo (Tate, 1933); Casabindo, m (Thomas, 1919b, as Marmosa elegans pallidior); Humahuaca (Thomas, 1919a, as Marmosa elegans pallidior). Comments.--All records of this species correspond to the High Andean, Puna, and Prepuna regions. At 9 km NW Bárcena, this species was collected with T. sponsorius, a species known only from the Yungas and Chaco provinces. Bárcena is in an ecotone between Prepuna and Yungas. Offspring were recorded in February and April, juveniles in February and March, and subadults in April and May. A lactating female was captured in December, with 9 abdominal mammae, 8 forming a circle around a central one, and as is typical for this genus the hair around the mammae was pigmented. Specimens with incrassate tails were recorded in February, March, and December. Molting specimens were observed in February and March. The specimen from Mina Pan de Azúcar is represented by a toothrow found in feces. Thylamys sp. Specimens Examined (1).--Cerro Calilegua, El Duraznillo, 3000 m, 1 (CML 1718). Comments.--The specimen cited by Heinonen and Bosso (1994) as Thylamys elegans is deposited at the CML and the same as that cited by Olrog (1979) as M. pusilla pallidior. This specimen was examined at CML and does not correspond with any of the known species from northwestern Argentina (Flores et al., 2000), so it is here treated as

15 Díaz and Barquez: Wild Mammals of Jujuy Province, Argentina 431 Thylamys sp. The record is from a region of alder (Alnus) forests with some specimens of queñoa trees (Polylepis), according to Olrog (1979) and Heinonen and Bosso (1994). Additional specimens from the area are needed to confirm the identity of this species. Thylamys sponsorius (Thomas, 1921) Fat-tailed Mouse Opossum Marmosa elegans sponsoria Thomas, Annals and Magazine of Natural History, ser. 9, 7:186. Distribution in Argentina.--In Argentina this species was only known for the province of Jujuy, but recently was reported from Salta and Tucumán provinces (Flores et al., 2000).

Comments.--All localities for this species in Jujuy Province correspond to the Yungas, except for a few that are in the Prepuna and Chaco. This distribution indicates a preference for humid and dense vegetation, contrasting with T. cinderella, which prefers dry and disturbed areas in the Chaco, as well as transitional and Yungas forest. The type specimen was captured in Yungas inside of a hole in a cedar tree (Cedrela sp.); other specimens were collected in trees or fallen logs at the localities Arroyo Yuto, Sunchal, and Higuerilla. Specimens at CML cited by Olrog (1979) as Marmosa elegans cinderella from Cerro Calilegua are here reidentified as Thylamys sponsorius; the precise locality is Abra de Cañas, El Monolito. The locality Near Vala (cited by Tate, 1933) for Marmosa venustus sponsoria, is indicated in the original specimen label as Mountains W of Yala and the correct name of the locality indicated by this author as Carmencito is Caimancito. Tate

16 432 University of California Publications in Zoology (1933) included M. v. cinderella and M. v. sponsoria in Caimancito, 400 m; however, this was based on the error of assigning the same specimen (BMNH ) to 2 different subspecies at 1 locality. A pregnant female and a lactating female were collected in December. Subadults were captured in May, July, and August. Specimens with incrassated tails have been recorded in June and July.

Specimens Examined (1).-- Jujuy, 1 (FMNH 21672). Comments.--Although Chébez (1994) stated that there are no well-documented records to confirm the presence of this species in Argentina, we examined a specimen from Jujuy at FMNH. Additionally, Redford and Eisenberg (1992) mentioned this species from Misiones, Formosa, and Chaco provinces, and reported 2 individuals from Jujuy, at the Zoo in Buenos Aires. The record at the FMNH corresponds to a tanned skin of a specimen captured during the Argentine Commission Panama Pacific Exposition in During our field trips, this species was not observed by us and was not reported by rural residents.

Comments.--According to Wetzel (1985) this species might be a highland subspecies of C. vellerosus, although material is lacking to confirm this conclusion (Chébez, 1994). This species is found only in the Andean grasslands and shrubs (Redford and Eisenberg, 1992; Anderson, 1997). The specimens cited by Crespo (1944) as C. v. vellerosus, based on distribution, were reidentified by us and are here considered to be C. nationi, because of the size and shape of the cephalic shield. Chaetophractus vellerosus (Gray, 1865) Screaming Hairy Armadillo Dasypus vellerosus Gray, Proceedings of the Zoological Society of London, 376. Distribution in Argentina.--In Argentina this species is distributed from Jujuy south to Mendoza, San Luis, La Pampa, and Buenos Aires (Vizcaíno et al., in press). Specimens Examined (28).--Chanchillos, 2 (MACN 42.99, 42.98); Jujuy, 20 (MACN , , , , 32.43, 32.44, 32.78, , , , , , , , , , , , , ); Perico, 2 (MACN , ); San Antonio, 2 (MACN , ); Vinalito, Yuto, 1 (CML 398); Yuto, 1 (AMNH ).

Deterville, Paris, 24:28. Distribution in Argentina.--This species is distributed in the provinces of Corrientes,

18 434 University of California Publications in Zoology Chaco, Formosa, and Jujuy, southward to Mendoza and Río Negro; it likely occurs in Misiones as well (Cabrera, 1958; Wetzel and Mondolfi, 1979). Specimens Examined (2).-- Jujuy, 2 (MACN , ). Comments.--Only 2 specimens of this species were examined for the province of Jujuy, both without specific locality, collected by Dr. S. Mazza in Dasypus novemcinctus Linnaeus, 1758 Nine-banded Armadillo Dasypus novemcinctus Linnaeus, Systema Naturae per regna tria naturae, secundum classis, ordines, genera, species cum characteribus, differentiis, synonymis, locis. Tenth edition. Laurentii Salvii, Stockholm, 1:51. Distribution in Argentina.--Previously, this species was known from Misiones, Formosa, Chaco, eastern Salta, and Santiago del Estero provinces (Cabrera, 1958; Wetzel, 1985). It is here included in the fauna of Jujuy Province (Díaz and Barquez, 1999). Specimens Examined (1).-- Jujuy, 1 (MACN ). Comments.--The specimen examined, representing the first record of the species for the province (Díaz and Barquez, 1999), was collected by A. Fiora in Dasypus yepesi Vizcaíno, 1995 Yepes Armadillo Dasypus yepesi Vizcaíno, Mastozoología Neotropical, 2(1):5-13 Distribution in Argentina.--Salta and Jujuy provinces (Vizcaíno, 1995). Specimens Examined (1).--Abra de Cañas, El Monolito, 1700 m, 1 (CML 1809). Additional Records.--Abra de Cañas, 1700 m (Olrog, 1976, as D. mazzai), Cerro Calilegua (Olrog, 1979, as D. mazzai); El Alto, Río Caulario, 1200 m; El Caulario, Río Caulario, 940 m; Finca La Mauricia, 5-10 km al E de Caimancito, 500 m; Finca La Realidad, Río San Francisco, 5 km al E de Caimancito, 440 m (Vizcaíno, 1995). Comments.--Vizcaíno (1995) agreed with Hamlett (1939) and Wetzel and Mondolfi (1979) that the holotype of D. mazzai corresponds to D. novemcinctus, while the paratype corresponds to D. yepesi. Consequently, all of the specimens of D. mazzai in systematic collections require re-examination. Olrog (1976, 1979) reported D. mazzai in 2 localities of Jujuy, which probably correspond to a single specimen deposited at the CML (1809), and here re-identified as D. yepesi. Moreover, the armadillo from Palpalá that was cited as D. mazzai by Yepes (1933b) could correspond to any of the species actually cited for the province. All records correspond to the Yungas.

Comments.--Heinonen and Bosso (1994) have included this species in Abra de Cañas under the argument that this was a locality indicated by Olrog (1979) for this species; however, Olrog only reported E. sexcinctus for the locality San Francisco. This species is found in dry savannas; according to local residents, it is a good predator and may eat small vertebrates.
