(COLEOPTERA, LEIODIDAE, LEPTODIRINI), A NEW ENDOGEAN BEETLE FROM SERBIA S. B. ĆURČIĆ, S. E. MAKAROV, and B. P. M. ĆURČIĆ Institute of Zoology, Faculty of Biology, University of Belgrade, Belgrade, Serbia Abstract A new species of endogean leptodirine leiodids (Magdelainella studenicae sp. n.) from the valley of the Studenica River, village of Miliće, near Ušće in Southwest Serbia, is diagnosed and described. This new species differs clearly from all other closely related taxa. Magdelainella Jeannel belongs to a phyletic lineage which includes three more genera: Knirschiella Guéorguiev, Kosaniniella S. Ćurčić, Brajković & B. Ćurčić, and Derveniella Pavićević & Perreau. Derveniella is given full generic status in the present paper; its members are known from Southeast Serbia only. Magdelainella noesskei (Apfelbeck), M. winkleri Jeannel, M. bozidarcurcici S. Ćurčić & Brajković, M. mucanjensis S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. milojebrajkovici S. Ćurčić & B. Ćurčić, M. zivojindjordjevici S. Ćurčić, Brajković, B. Ćurčić & Schönmann, and M. nikolateslai S. Ćurčić, Brajković, B. Ćurčić & Schönmann are sharply delimited and represent valid species. The following new combinations are proposed for three species of Magdelainella: Kosaniniella hussoni (Jeannel), comb n., K. nonveilleri (Pavićević & Perreau), comb. n., and K. orientalis (Pavićević & Perreau), comb. n. The Magdelainella-Knirschiella-Kosaniniella-Derveniella complex is probably of Mesogeid age and origin; its species originated during the Alpine Orogeny, which affected vast areas of the Balkan Peninsula, their terra typica. Key words: Coleoptera, Leiodidae, Magdelainella studenicae, new species, revision, endogean fauna, Serbia Udc :591.5(497.11) INTRODUCTION The subterranean and endogean invertebrates of Serbia have been the object of extensive and intensive investigations in the recent past and are well-known for their high specific diversity and exceptional specialization of many taxa (Ćurčić, 2002). However, the leiodid fauna in Serbia is insufficiently known. A great number of endogean and cave taxa from the subfamily Cholevinae were described in the first half of the 20 th century, among which the three species of the genus Magdelainella Jeannel from Serbia M. serbica (Müller), M. winkleri Jeannel, and M. hussoni Jeannel (Müller, 1904; Jeannel, 1924, 1934). M. serbica and M. hussoni were subsequently found in Montenegro (Pavićević and Perreau, 2008). Additional cave-dwellers and endogean species were found only recently M. bozidarcurcici S. Ćurčić & Brajković, M. zivojindjordjevici S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. mucanjensis S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. nikolateslai S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. milojebrajkovici S. Ćurčić & B. Ćurčić, M. nonveilleri Pavićević ć & Perreau, M. orientalis Pavićević ć & Perreau, and M. (Derveniella) stevanovici Pavićević & Perreau (Ćurčić and Brajković, 2002; Ćurčić et al., 2004, 2005; Pavićević ć and Perreau, 2008). Apart from Serbia, this genus contains also two species from Bosnia-Herzegovina, M. kauti (Apfelbeck) and M. noesskei (Apfelbeck) (Apfelbeck, 1907, 1919). Knirschiella Guéorguiev is removed from the genus Magdelainella and is given full generic status (Ćurčić et al., 2004a). Its members are presently known from Albania. A thorough study of a sample of leptodirine beetles from Southwest Serbia has enabled us to establish a new species, Magdelainella studenicae sp. n. The description of this new species is based on the study of the holotype male, paratype male, and paratype female. The type specimens are deposited in the collection of the Centre for Biospeleology, 757

2 758 S. ĆURČIĆ et al. Institute of Zoology, Faculty of Biology, University of Belgrade, Serbia (CBIZ ). Since the present knowledge imposes the necessity of a critical revision of some Magdelainella, we propose new status and new combination for some taxa considered herein in this paper. MATERIALS AND METHODS The leiodid beetles were fixed on paper lebels and then analyzed as dry specimens. Genital structures were removed from insect bodies and fixed on microscope slides in a medium composed of Canada balsam and xylol. The specimens obtained were analyzed in detail in laboratories of the Institute of Zoology, Faculty of Biology, University of Belgrade. Carl Zeiss-Stemi 2000 and Carl Zeiss-Ergaval binocular stereomicroscopes were used in this study, together with a special monitor and accessories for drawing. RESULTS AND DISCUSSION LEIODIDAE FLEMING, 1821 MAGDELAINELLA JEANNEL, 1924 Remarks. The following Magdelainella species are considered as good: Magdelainella noesskei (Apfelbeck), M. winkleri Jeannel, M. bozidarcurcici S. Ćurčić & Brajković, M. mucanjensis S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. milojebrajkovici S. Ćurčić & B. Ćurčić, M. zivojindjordjevici S. Ćurčić, Brajković, B. Ćurčić & Schönmann, and M. nikolateslai S. Ćurčić, Brajković, B. Ćurčić & Schönmann. Pavićević and Perreau (2008) treated first five aforementioned species as synonyms of Magdelainella serbica (Müller), and two last mentioned as synonyms of M. hussoni Jeannel. We deny such superficial opinion of these two authors; actually, this paper lacks a serious scientific analysis and the authors did not analyze any of the type specimens of each of the mentioned species. All descriptions and diagnoses by Pavićević and Perreau (2008) are redundant and insufficient and many valid comparative data are completely missing. MAGDELAINELLA STUDENICAE, NEW SPECIES (Figs. 1-8) Etymology. After the valley of the Studenica River, its terra typica. Material examined. Holotype male from the valley of the Studenica River, from under rocks and leaflitter, village of Miliće, near Ušće, Southwest Serbia, collected by B. Ćurčić and D. Stojanović, 20 August 2006; paratype male and paratype female, from under stones, same locality, collected by S. Ćurčić, S. Makarov, and D. Stojanović, 8-9 September Diagnosis. Magdelainella studenicae sp. n. is phenetically close to the following species from Serbia: M. serbica (Müller), M. winkleri Jeannel, M. bozidarcurcici S. Ćurčić & Brajković, M. zivojindjordjevici S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. mucanjensis S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. nikolateslai S. Ćurčić, Brajković, B. Ćurčić & Schönmann, and M. milojebrajkovici S. Ćurčić & B. Ćurčić. From M. serbica, the new species clearly differs by the presence/absence of eyes (absent vs. present), length of last antennomere (shorter than the two precedent antennomeres taken together vs. as long as the two precedent antennomeres taken together), form of elytra (not narrowed backwards vs. somewhat narrowed backwards), form of mesosternal carina (almost right-angled vs. obtuseangled), form of median lobe (dragged apically vs. obtuse apically), features of inner sac (without any gutter-like structures vs. with an inverse Y-formed gutter-like structure), form of aedeagus in lateral view (median lobe more curved apically and more convex dorsally, parameres narrower vs. median lobe less curved apically and less convex dorsally, parameres wider), form of gonostylus (somewhat rounded proximally vs. not rounded proximally), and form of spermatheca (angulosely curved, with a large apical lobe vs. roundly curved, with a small apical lobe). From M. winkleri, the new species is clearly distinct by the form of the body (more parallel vs. more oval), presence/absence of eyes (absent vs.

From M. nikolateslai, the new species is clearly distinct by the body size (2.37 mm vs mm), body color (brownish vs. yellow-brownish), presence/ absence of eyes (absent vs. present), length/width ratios of some antennomeres (III: 1.75 vs. 2.00; VII: 1.29 vs. 1.20; XI: 1.67 vs. 1.50), length of antennomere III (slightly longer than demi-antennomere II vs. as long as demi-antennomere II), form of antennomere XI (with minute anterior depressions vs. without any anterior depressions), width/length ratio of pronotum (2.09 vs. 1.75), maximum width of elytra (just before their fore fifth vs. at the level of their anterior quarter), form of gonostylus (more elongated, gradually narrowing apically vs. less elongated, sharply narrowing apically), and form of spermatheca (almost straight vs. roundly curved). From its close congener, M. milojebrajkovici, M. studenicae sp. n. is easily distinguished by the different body size (2.46 mm vs mm), body color (brownish vs. yellow-brownish), presence/ absence of eyes (absent vs. present), antennal length (not reaching the level of the pronotum base vs. reaching the level of the pronotum base), length of antennomere III (almost twice as long as wide, shorter than demi-antennomere II vs. twice as long as wide, as long as demi-antennomere II), shape of anterior pronotal angles (obtuse vs. prominent), maximum width of pronotum (at the level of its third fourth vs. at the level of its fourth fifth), form of pronotal base medially (protruding backwards vs. straight), apex of median lobe (roundly pointed vs. blunt), form of tegmen (rounded vs. more elongated), length of parameres (not reaching the level of the median lobe apex vs. reaching the level of the median lobe apex), form of parameral apex (convex exteriorly vs. flattened exteriorly), and features of inner sac (without a gutter-like structure, with two simple teeth vs. with an inverse Y-formed gutter-like structure, with two bifid teeth).

As presented in the paper of Pavićević and Perreau (2008). Distribution. The genus Derveniella is presently known only from endogean localities on Mts. Svrljiške Planine and Mt. Suva Planina, as well as from the vicinity of Dimitrovgrad in the southeastern part of Serbia. Remarks. The genus Derveniella probably belongs to a separate phyletic lineage which originated during the Paleogene. The endemic differentiation of Derveniella and its related genera (Magdelainella, Knirschiella, and Kosaniniella) in the central part of the Balkan Peninsula was facilitated by the great Alpine Orogeny, paleoclimatic events, and subsequent evolution of the underground karstic relief which yielded many new epigean hypogean niches suitable for preserving this old and autochthonous fauna. Thus, the genus Derveniella represents an endemic and relict taxon inhabiting Serbia and the Balkan Peninsula. KOSANINIELLA S. ĆURČIĆ, BRAJKOVIĆ & B.

Description and diagnosis. As presented in the paper of Jeannel (1934). Distribution. This species is presently known both from caves and endogean localities on Pešter plateau (Southwestern Serbia), as well as from a single cave in Northeastern Montenegro. Remarks. After analyzing some new, previously not used morphological features of M. hussoni (shape of parameral apex, form of parameres laterally, position of parameral setae, structure of teeth from the inner sac, shape of spermatheca), we concluded that this species actually belongs in the genus Kosaniniella S. Ćurčić, Brajković & B. Ćurčić. This species is not present on Mts. Javor, Stari Vlah, Murtenica, and Goč, as Pavićević and Perreau (2008) stated. The mentioned paper comprises superfluous descriptions of two new Magdelainella species, their diagnoses missing, and the manuscript is overloaded with technical mistakes and misunderstandings. We stay at the opinion that Magdelainella nikolateslai S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. zivojindjordjevici S. Ćurčić, Brajković, B. Ćurčić & Schönmann, and Kosaniniella javorensis S. Ćurčić, Brajković & B. Ćurčić are good, well-recognizable

8 764 S. ĆURČIĆ et al. species belonging to two separate genera (Ćurčić et al., 2004, 2004a). They are not the synonyms of Magdelainella hussoni, like Pavićević and Perreau (2008) erroneously stated.

Type localities. 540 m a. s. l., Mt. Bukulja, Central Serbia; village of Tresije, Mt. Kosmaj, Central Serbia; village of Donja Šatornja, Mt. Rudnik, Central Serbia; village of Gruža, near Kragujevac, Central Serbia; Pećina u Brezacima Cave, village of Brezaci, 690 m a. s. l., Rajac, Mt. Suvobor, Western Serbia. Description and diagnosis. As presented by Pavićević and Perreau (2008), but lacking numerous data on morphology and morphometric ratios and linear measurements of the species mentioned. Distribution. This species is presently known mainly from endogean localities from the mountains (Bukulja, Kosmaj, and Rudnik) and lower areas of the Šumadija Region. Remarks. Shape of parameral apex (narrowed), form of parameres in lateral view (slightly sigmoid), position of parameral setae (one inner seta borne below two other setae), structure of teeth from the inner sac (two pairs of subequal teeth), and shape of spermatheca (with two spherical close-set lobes) indicate that this form actually belongs in the genus Kosaniniella. Both the original description and diagnosis should be enriched with numerous additional data since they lack basic information about essential morphological features of the taxon in question. KOSANINIELLA ORIENTALIS (PAVIĆEVIĆ & PERREAU, 2008), COMB. N. Old combination. Magdelainella (s. str.) orientalis: Pavićević & Perreau, Adv. Stud. Fauna Balkan Penins., 2008, 192. Type locality. Village of Ceremošnja, 600 m a. s. l., Mt. Homoljske Planine, Eastern Serbia. Description and diagnosis. A short description of this species is presented in the paper of Pavićević and Perreau (2008) (two sentences only), but its diagnosis is completely lacking. The authors presented a single drawing of the aedeagus of this species, but its habitus and important female morphological structures are completely missing. Numerous data on morphology and morphometric ratios and linear measurements of the species considered should be provided because the mentioned authors just simply omitted these in full. Distribution. This species is currently known from an endogean locality on Mt. Homoljske Planine in the eastern part of Serbia. Remarks. Shape of parameral apex (narrowed), form of parameres in lateral view (slightly sigmoid), position of parameral setae (one inner seta borne below two other setae), and structure of the teeth from the inner sac (two pairs of subequal teeth) indicate that this form actually belongs in the genus Kosaniniella. Both the original description and diagnosis should be further enriched with numerous missing data since they lack any information about main features of this taxon.

(COLEOPTERA, LEIODIDAE, LEPTODIRINI), НОВОГ ЕНДОГЕЈСКОГ ТВРДОКРИЛЦА ИЗ СРБИЈЕ С. Б. ЋУРЧИЋ, С. Е. MAКАРОВ и Б. П. M. ЋУРЧИЋ Институт за зоологију, Биолошки факултет, Универзитет у Београду, Београд, Србија Нова врста ендогејских лептодирина лејодида (Magdelainella studenicae sp. n.) из долине реке Студенице, село Милиће, близу Ушћа у југозападној Србији је дијагностификована и описана. Ова нова врста се јасно разликује од свих својих сродника на основу већег броја корелативних особина. Magdelainella Jeannel припада засебној филетичкој линији која укључује и следећа три рода: Knirschiella Guéorguiev, Kosaniniella S. Ćurčić, Brajković & B. Ćurčić и Derveniella Pavićević ć & Perreau. Derveniella је уздигнута на ниво рода у овој студији; припадници овог рода су за сада познати само из југоисточне Србије. Magdelainella noesskei (Apfelbeck), M. winkleri Jeannel, M. bozidarcurcici S. Ćurčić & Brajković, M. mucanjensis S. Ćurčić, Brajković, B. Ćurčić & Schönmann, M. milojebrajkovici S. Ćurčić & B. Ćurčić, M. zivojindjordjevici S. Ćurčić, Brajković, B. Ćurčić & Schönmann и M. nikolateslai S. Ćurčić, Brajković, B. Ćurčić & Schönmann представљају валидне врсте. Предложене су нове комбинације за три врсте које су припадале роду Magdelainella: Kosaniniella hussoni (Jeannel), comb n., K. nonveilleri (Pavićević & Perreau), comb. n. и K. orientalis (Pavićević & Perreau), comb. n. Комплекс Magdelainella-Knirschiella- Kosaniniella - Derveniella је вероватно мезогеидне старости и порекла. Алпска орогенеза је деловала на простране области Балканског полуострва, где су се населиле врсте које припадају споменутом комплексу родова.
