A new leptodirine leiodid beetle species, Pholeuonopsis (Pholeuonopsis) sljivovicensis sp. n., from a cave in western Serbia is described and diagnosed. The views of both male and female genitalia ...and other taxonomically important characters are imaged. The new species is clearly distinct from the closest relatives. It probably belongs to an old phyletic lineage of Mesogeid origin, like other known Pholeuonopsis taxa from the western part of the Balkan Peninsula. The new species is both an endemic and a relict inhabiting solely western Serbia. Morphological comparisons among the Serbian Pholeuonopsis species are provided, together with a key to the species. The genus Serbopholeuonopsis B. Ćurčić & Boškova, 2002 is regarded as a junior synonym of the genus Pholeuonopsis Apfelbeck, 1901.
Two new species of Anthroherpon belonging to the "ganglbaueri" species group are described from northern Montenegro: Anthroherpon sinjajevina n. sp. and Anthroherpon cecai n. sp. Based on ...morphological investigations of other species of this group, we elevate A. udrzali Giachino & Vailati from subspecies to species rank, and suggest the synonymy of A. brckoensis Giachino & Guéorguiev with A ganglbaueri alticola Knirsch. An identification key of the ganglbaueri species group (sensu Guéorguiev, 1990) is given and the distributions of species and subspecies are mapped and discussed.
In this paper we describe T. pallisei sp. n., a new representative of the genus Troglocharinus Reitter, 1908 (Coleoptera, Leiodidae, Leptodirini), a strictly subterranean genus restricted to the ...Eastern Pyrenees and some coastal areas in Catalonia. All known specimens of T. pallisei sp. n. were collected in a cave next to the town of La Riba, in the province of Tarragona (Spain), situated between the distribution areas of the species of the T. orcinus complex and T. espanoli Jeannel, 1930. It can be separated from the other members of the T. orcinus complex by the presence of penicillus in the apex of the parameres of the aedeagus and from T. espanoli by the presence of a mesoventral keel; it also differs from both by its long and erect pubescence. A Bayesian molecular phylogeny including representatives of the main lineages within the genus Troglocharinus, based on ca. 5211 Kb of 5 mitochondrial and 4 nuclear genes, placed T. pallisei sp. n. as sister to T. orcinus Jeannel, 1910, and both sister to T. espanoli, in perfect agreement with their geographic distributions and the inferred geographic expansion of the genus to the south, with an estimated divergence of ca. 1.3 Ma. In agreement with the results of a previous phylogenetic study, the subgenus Antrocharidius Jeannel, 1910 is synonymised with Troglocharinus (syn.n.).
Karyotypes are shown for Leiodes calcarata (Erichson, 1845), Catops coracinus Kellner, 1846, Cantabrogeus luquei (Salgado, 1993), Espanoliella luquei Salgado & Fresneda, 2005, Fresnedaella lucius ...Salgado, Labrada & Luque, 2011, Notidocharis uhagoni (Sharp 1872), Quaestus (Quaesticulus) pasensis Salgado, Labrada & Luque, 2010, all of which are shown to have a diploid number of 20 autosomes plus Xy (♂) or XX (♀) sex chromosomes, as well as an as yet undescribed triploid species of the genus Cantabrogeus Salgado, 2000. These results are contrasted with published information, all on Leptodirini, which lists 10 species as having diploid numbers of 22 + Xy or XX. It is shown that the higher chromosome number (n = 11 + X or y) previously reported refers exclusively to the more derived Leptodirini ("infraflagellates") whereas the lower number (n = 10 + X or y) refers to the less derived surface-dwelling forms and the less derived Leptodirini ("supraflagellates").
Se describe una nueva especie del género Bathysciola Jeannel, 1910 –Bathysciola fadriquei n. sp.– perteneciente al grupo schiodtei; ésta ha sido hallada en medio subterráneo profundo, en dos cuevas ...situadas en Sierra de Bernera, macizo del Bisaurín, Pirineo de Huesca, Aragón, España. Los caracteres diferenciales se encuentran básicamente en las estructuras genitales: la nueva especie se caracteriza por presentar en el complejo faneroide del saco interno del edeago unas faneras apicales muy grandes, triangulares, fuertemente esclerotizadas, con un lóbulo exterior asociado. Se discute la posición taxonómica. Se completa el estudio con ilustraciones de las estructuras que permiten su diferenciación, clave de identificación y datos de distribución.
Eskualdunella delespierrei Coiffait, 1950 : the key for a biogeographic enigma (Coleoptera, Leiodidae). The study of the only known specimen of Eskualdunella delespierrei Coiffait, 1950, allowed us ...to discover that this enigmatic beetle belongs to a well-known genus of Leptodirini from French Alps, the genus Cytodromus Abeille de Perrin, 1876. We present here a comparative study of the type of Eskualdunella delespierrei and an exemplar of Cytodromus dapsoides (Abeille de Perrin, 1875), and we establish the synonymy of the two genera and the two species : Cytodromus Abeille de Perrin, 1876 = Eskualdunella Coiffait, 1950, n. syn. and Cytodromus dapsoides (Abeille de Perrin, 1875) = Eskualdunella delespierrei Coiffait, 1950, n. syn. Troglobiomorphic – pholeuonoid – species of north-pyrenean Leptodirini (genera Perriniella Jeannel, 1910, Antrocharis Abeille de Perrin, 1876, Gesciella Giachino & Guéorguiev, 1989, Troglophyes Abeille de Perrin, 1894, and Trocharanis Reitter, 1885) are then only known eastern to Garonne valley.
L'étude du seul exemplaire connu d'Eskualdunella delespierrei Coiffait, 1950, nous a permis de mettre en évidence que cet insecte énigmatique appartient en fait à un genre bien connu de Leptodirini des Alpes françaises, le genre Cytodromus Abeille de Perrin, 1876. Nous présentons une étude comparative de l'holotype d'Eskualdunella delespierrei et d'un exemplaire de Cytodromus dapsoides (Abeille de Perrin, 1875), et établissons la synonymie des deux genres et des deux espèces : Cytodromus Abeille de Perrin, 1876 = Eskualdunella Coiffait, 1950, n. syn. et Cytodromus dapsoides (Abeille de Perrin, 1875) = Eskualdunella delespierrei Coiffait, 1950, n. syn. Les formes déliées – pholeuonoides – de Leptodirini nord-pyrénéens (genres Perriniella Jeannel, 1910, Antrocharis Abeille de Perrin, 1876, Gesciella Giachino & Guéorguiev, 1989, Troglophyes Abeille de Perrin, 1894, et Trocharanis Reitter, 1885) ne sont donc pour l'heure connues qu''à l'est de la vallée de la Garonne.
