''Leptodirus hochenwartii'', or ''L. hohenwarti'',〔The name is a source of some confusion; the beetle was originally named ''Leptodirus Hochenwartii'', but the specific name is linguistically incorrect, and there are several spelling variants of the name of the person it was named after. Many sources therefore write it as ''hohenwarti''.〕 is a cave beetle in the family Leiodidae and the only species in the genus ''Leptodirus''. It is a true troglobite, adapted to the life underground and unable to survive outside. Its distinguishing features are slender thorax, elongated legs and antennae, the absence of pigment in the integument, and completely reduced eyes. But perhaps the most striking feature are the domed elytrae which cover the abdomen completely and give it a round (so-called "physogastric") appearance. It lives predominantly in large caves where the temperature does not exceed 12 °C.〔Vrezec A. et al. (2007) (Monitoring populacij izbranih ciljnih vrst hroščev (končno poročilo) ) (Monitoring of selected populations of target beetle species). Natura 2000 report. 〕 Its ecology is largely unknown, but the specimens were seen feeding on carcasses of different cave animals and other organic material. Even less is known about its life history; the only study done so far determined that it reproduces and grows slowly. Females lay a small number of relatively large eggs which take a long time to develop. The number of larval instars is reduced to only one, and the larvae do not feed before moulting.〔Deleurance-Glaucon S. (1963). "Resherches sur les Coleopteres trolobites de la sousfamille des Bathysciinae". ''Ann. Sci. Natur. Zool.'' 12(5): 1-172, as quoted in Vrezec et al. (2007).〕 ==Taxonomy and range== ''L. hochenwartii'' is endemic to western Dinaric Alps. Six subspecies are currently recognized:〔 * ''L. hochenwartii hochenwartii'' Schmidt, 1832 * ''L. hochenwartii reticulatus'' J. Müller, 1906 * ''L. hochenwartii schmidti'' (Motschoulsky, 1856) * ''L. hochenwartii croaticus'' Pretner, 1955 * ''L. hochenwartii velebiticus'' Pretner, 1970 * ''L. hochenwartii pretneri'' Müller, 1926 Of those, three are found in Slovenia, and the others are found in Croatia.〔Polak S.

Accessed 2007-11-20. 〕 The southernmost known location is Velebit range in Croatia where subspecies ''L. h. velebiticus'' was described, and subspecies ''L. h. reticulatus'' was originally found in Grota Noe near Trieste (Italy).〔 The exact status of several subspecies and forms is problematic to determine because specimens can differ significantly in physical characteristics even within the same population. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leptodirus hochenwartii」の詳細全文を読む スポンサード リンク
