230 Lohaj, R. & Jal`i}, B.: Minosaphaenops croaticus, new species of the cave dwelling Trechinae beetle INTRODUCTION Seven genera of aphaenopsoid Trechinae beetles are known from the territory of the Dinarides: Albanotrechus Casale & Guéorguiev, 1994 with one species from Central Albania; Aphaenopsis G. Müller, 1913 with two species from Central Bosnia Mts Treskavica and Bjela{nica; Scotoplanetes Absolon, 1913 with one species from southern Herzegovina Vjetrenica pe}ina cave near Zavala village and Mrcine pe}ina cave near Grebci village, and from Montenegro new finding from Vodna jama pit on Dragaljsko polje near Umac (G. Dunay & J. Lakota, pers. comm.), Dalmataphaenops Monguzzi, 1993 (Biokovoaphaenopsis Jal`i}, 1993, junior synonym) with one species from Mt. Biokovo in Croatia; Adriaphaenops Noesske, 1928 with seven currently described species from Herzegovina and Montenegro (PRETNER, 1959; PAVI]EVI], 1990, 2001; QUÉINNEC, 2008; QUÉINNEC & PAVI]EVI], 2008; QUÉINNEC, PAVI]EVI] & OLLIVIER, 2008), as well as two monotypical recently described genera Minosaphaenops Quéinnec, 2008 from Mt. Krivo{ije, Montenegro and Derossiella Quéinnec, 2008 from Mt. Mosor, Croatia (JEANNEL, 1928, 1930; CASALE & LANEYRIE, 1982; DROVENIK & PEKS, 1994; MORAVEC et al., 2003; QUÉINNEC, 2008). Genus Minosaphaenops Quéinnec, 2008 with the type species Minosaphaenops ollivieri was described based on five specimens collected in three pits located in the Krivo{ije mountain range in Montenegro. During the biospeleological research of Glogova jama pit near Kuna Konavoska, Snije`nica mountain range, southeastern Croatia, another specimen belonging to this genus was collected by the second author. This new species is described herein. Genus Derossiella Quéinnec, 2008 with the type species Derossiella nonveilleri was described based on a single female, collected in April 1999 in a nameless pit ca. 15 m deep and ca. 500 meters SSE from Bali}eva {pilja (Kraljeva jama), Bali}, Mt. Mosor, Croatia. Because of the newly collected male specimen from Drinov~u{a jama near Kotlenice, Mt. Mosor in August 2007, we were given the opportunity to provide description of this species male for the first time. The description is given here below. MATERIAL AND METHODS The morphological features of the beetles were examined using the stereoscopic microscope Olympus SZ 60. Macrophotos were taken using the stereoscopic microscope LEICA S8 APO with the digital camera NIKON COOLPIX E 4500. Male genitalia were dissected, cleaned and mounted in Euparal on transparent labels under the examined specimens. Drawings of aedeagi were made using the Zeiss transmitted-light microscope and drawing tube. Abbreviations used in the text are as follows: TL: total body length (measured from the anterior margin of clypeus to the apex of elytra) AL: antennal length (measured from the base of antennal scape to the apex of terminal antennal segment) HW: maximum width of head

Nat. Croat. Vol. 18(2), 2009 233 the level of anterior supraorbital setae divergent and evanescent. Dorsal part of the head covered with short pubescence, anteriorly denser than posteriorly, genae sparsely pubescent. Head with two pairs of supraorbital setae, anterior pair in front of the middle part of head, near furrows, posterior pair at hind part of head near neck, eyes absent. Mandibles long and slender, acutely pointed, right mandible without visible retinaculum. Antennae relatively long and slender, 3.58 mm long, lengths of antennal segments (from scape to terminal segment): 0.25, 0.25, 0.4, 0.33, 0.4, 0.37, 0.35, 0.33, 0.28, 0.3, 0.32 mm. Pronotum narrow, elongate, subparallel, index PL/PW 1.61, slightly narrower than the head, propleura visible from dorsal view. Anterior angles of pronotum protruding, acute, posterior angles obtuse. Lateral groove deep, with a single pair of anterior setae on basal sixth, posterior pair of setae absent. Pronotum dorsally sparsely pubescent, setae short, suberect, median line inconspicuous. Elytra subovate elongate, its maximum width at the apical third, index EL/EW 1.64. Basal part strongly narrowed, pedunculate, scutellum small, single pair of basal scutellar setiferous pores present. Elytral striae invisible. Elytral chetotaxy as follows: four macrochetae present in putative stria 3, two microchetae located before macrocheta 1, two microchetae between macrochetae 1 2, interspace between macrochetae 2 3 devoid of microcheta, two microchetae located between macrochetae 3 4, preapical seta short and thin. Six microchetae present in putative stria 2. Abdominal sternites glabrous, pubescence absent, with a single pair of thick and short setae. Legs relatively short, slender, densely pubescent. First two tarsomeres protarsi distinctly dilated and protracted at their internal margins. Tarsal claws very long and slender, without traces of denticulation on their internal sides. Aedeagus (Fig. 4) 0.61 mm long, elongate, slender, basal part of medial lobe wider, narrowed towards apex. Apical part regularly narrow, apex obtuse, without a thickened tip. Parameres slender, length of parameres about half of the length of aedeagus, left paramera with one 1 long seta, right paramera with two setae. Female unknown. Etymology. Topotypic, referring to the country of origin, Croatia. Discussion. Genus Minosaphaenops Quéinnec, 2008 is morphologically similar to the genus Adriaphaenops Noesske, 1938, from which it differs by the following combination of characters: (1) elytra more or less glabrous (as opposed to completely pubescent in Adriaphaenops), (2) 3 rd elytral interval with 4 dorsal setae and one preapical seta (as 1 Note: Although left paramera of this newly described species bears a single seta and right paramera bears two setae, it is improbable that the missing seta of the left paramera was broken off or lost during the manipulation of the genitalia. The reason we believe this is the fact that there is no second setal pore present on the left paramere. Because only a single specimen is available, it is difficult to determine whether this represents an individual variation or a pattern. Furthermore, all three known males of Minosaphaenops ollivieri Quéinnec, 2008 have their parameres with two apical setae, but number of setae of parameres in Scotoplanetes Absolon, 1913 and Dalmataphaenops Monguzzi, 1993 varies between 4 5; Aphaenopsis G. Müller, 1913 presents 5 6 setae, respectively.

Derosiella nonveilleri Quéinnec, 2008. Scale 0.2 mm opposed to 2 dorsal setae and one preapical seta), (3) mentum without a median tooth (as opposed to mentum with simple median tooth). Type species of the genus, Minosaphaenops ollivieri was collected in three different pits (depth: 60 280 m) located in the Krivo{ije mountain range, south-eastern Montenegro: Ericova jama pit (holotype and a single paratype, both male), Maglena jama pit (a single paratype, female) and Jasenovska jama pit (two paratypes, both female). Localities on Mt. Krivo{ije are ca 25 km distant from Glogova jama pit. Minosaphaenops croaticus sp. nov. is strikingly similar to the type species of the genus, Minosaphaenops ollivieri Quéinnec, 2008. However, these two species can be easily separated using the following key: 1(2) Elytra wider, index EL/EW = 1.66, with maximum width in apical third. Head wider, index HL/HW = 1.64. Apical part of aedeagus regularly narrow, apex obtuse, without thickened tip. Smaller species, 5.1 mm. SE Croatia, Snije`nica mountain range... Minosaphaenops croaticus sp. nov.

Nat. Croat. Vol. 18(2), 2009 235 2(1) Elytra narrower, index EL/EW = 1.86 1.94, with maximum width in the middle. Head narrower, index HL/HW = 1.8 1.87. Apex of aedeagus with thickened tip. Larger species, 5.50 5.65 mm. Montenegro, Krivo{ije mountain range...... Minosaphaenops ollivieri Quéinnec, 2008 Topographic location and ecology: Glogova jama pit (UTM: BN81, Figs. 6, 7) is situated on an isolated karstic plateau of Snije`nica, above Konavle polje field, in the south-eastern part of Croatia. Cavernous abyss-shaped entrance is located above village of Kuna Konavoska in a beech forest at the elevation of about 950 m a.s.l. The pit was speleologicaly examined up to 146 m of its depth; there is light up to the depth of ca 100 m. Under the entrance of the vertical shaft and in deeper parts of the pit there are fields and mounds covered with soil alluvium and organic debris. Deepest parts of the pit are formed mainly by fissures, seasonally with numerous water streams. Red-billed chough (Pyrrhocorax pyrrhocorax Linné, 1758) nests here and brings plant seeds into the pit. Type specimen was found walking free on a wet drapery in a sideway tunnel at depth of about 115 m (see scheme of the pit). Temperatures measured on August 20th, 2005: Air: 3.7 C Water: 3.4 C Fig. 6.

236 Lohaj, R. & Jal`i}, B.: Minosaphaenops croaticus, new species of the cave dwelling Trechinae beetle Fig. 7. Topographical scheme of Glogova jama pit. Because of its position and morphology, Glogova jama is a unique pit refugium with hypogean fauna of Coleoptera, containing species that occur in neighbouring Montenegro and Bosnia & Herzegovina. Four taxa found here represent new genera and species for the fauna of Croatia, two of them Minosaphaenops croaticus sp. nov. and Blattochaeta marianii kusijanovici Polak & Jal`i}, 2009 ssp. nov. are even new for science. Coleopteran fauna found in Glogova jama pit: Carabidae, Trechinae: Minosaphaenops croaticus sp. nov.: new genus and species for the fauna of Croatia.

The shape of the median lobe of aedeagus and three setae on apical parts of parameres are unique feature found only in aphaenopsoid Trechinae of the Dinaric chain. Genera Adriaphaenops Noesske 1928 and Minosaphaenops have their median lobe slender and curved, apically narrowed, with two setae on each paramere (except for the holotype of Minosaphaenops croaticus sp. nov. with one seta on left paramere, see above). Genera Aphaenopsis G. Müller, 1913 and Scotoplanetes Absolon, 1913 have their median lobe more robust, with long apex and 4-5 apical setae in Scotoplanetes and 5 6 in Aphaenopsis. Genus Dalmataphaenops Monguzzi, 1993 has a very long and slender median lobe with 4 5 apical setae on each paramere. Shape of the median lobe of aedeagus in Derossiella Quéinnec is very similar to that of the Anatolian genera Kosswigia Jeannel, 1947 and Sbordoniella Vigna Taglianti, 1980 of the Neotrechus phyletic lineage, which have four setae on parameras. Notes. CHRISTIANSEN (1992: 463) presented common morphological troglomorphic characteristics, including specialisation of sensory organs (touch chemoreceptors, hygroreceptors, thermoreceptors, pressure receptors), elongation of appendages and foot modifications, pseudophysogastry, eyes reduction, pigment and wings reduction and increased egg volume. QUÉINNEC (2008: 170) in the chapter concerning the evolutionary trends of cave adapted species, shows that the so-called hyper-specialized Trechini present wide variability of external morphology in troglobiont genera occuring in the Dinaric chain. The following taxa were included in his study: Adriaphaenops Noesske, 1928, Minosaphaenops Quéinnec, 2008, Aphaenopsis G. Müller, 1913, Scotoplanetes Absolon, 1913, Dalmataphaenops Monguzzi, 1993, Derossiella Quéinnec and the peculiar genus Croatotrechus Casale & Jal`i}, 1999. The observed peculiarities included: body size, length of appendices (legs, antennae), pubescence of body, number and position of elytral setae, length and shape of frontal furrows and mandibles etc. The author observed that the so-called troglomorphic characters of this group are not readily defined, and there are no constant specific morphological features concerning the adaptability to the underground environment. Male genitalia, especially the shape of the median lobe, shape and number of setae on parameres in this group are likewise variable. Topographic location and ecology: Drinov~u{a jama pit (UTM: HJ32, Figs. 8, 9) is located in the well-developed karst area on the north slopes of Mosor mountain range near Bradari}a staje, above Tuki}i village at the altitude of about 740 m. Pit is 95 m deep, rift-shaped, fully vertical, with speleothems in the form of draperies situated in its western part. Bottom of the pit is covered by soil deposits, karst rocks and organic debris flooded from outer surface, with numerous seedlings
