A review of the aphaenopsian ground beetle genus Uenotrechus Deuve et Tian, 1999 (Coleoptera: Carabidae: Trechinae) Author Wei, Guofu Author Chen, Jujian Author Tian, Mingyi text Zootaxa 2017 4282 2 361 373 journal article 28748 10.11646/zootaxa.4282.2.9 41d9ff23-1bbd-426a-94dd-af487da76059 1175-5326 818748 EA9F4C08-5B46-45EF-8DBE-A66F7C6DBDCC Uenotrechus liboensis Deuve et Tian, 1999 ( Figures 2 , 3 , 5a–d) Deuve et al. , 1999 : 133 ( Type locality: Cave Jinshi Dong, erroneously written as “Shuijiang Dong” in the original description) Material examined. 1 male ( SCAU ), the holotype , labeled “ Jinshi Dong , 15 m below the entrance, Sanchahe , Libo , Guizhou , 108°4'10" E / 25°17'47" N , 580 m , IX-1997 , Jingcheng Ran leg.” ; 1 males and 1 female ( SCAU ), 1 male ( MNHN ), labeled “ Chang Dong , Baidan , Mulun National Nature Reserve (also the Huanjiang World Natural Heritage Site of Southern China Karsts), Huanjiang Maonan Autonomous County , Guangxi Zhuang Autonomous Region, 107°58’47.20″ E / 25°09’15.60″ N , VIII-26-2011 , Youbang Li leg., CHIgx11-LYB14” ; 1 male ( SCAU ), labeled “ Cave Gui Dong II , Mulun National Nature Reserve , Huanjiang County , Guangxi , 107°98’27.33″ E / 25°14’65.89″ N, V-18-2007 , Franck Brehier leg.”. Diagnosis. Large and eyeless trechine beetles, dark to yellowish brown, fore body darker; antennae and legs long; head expanded laterally, mentum 4-setose, mentum tooth bifid at tip; lateral margins of pronotum not sinuate before hind angles which are bluntly rectangular, base evidently arcuate forwardly; median lobe of aedeagus thin and slender, with a apical notch which is faintly reflexed ( Figs. 6 a–d). Habitus as in Fig. 3 . Variability. Individuals from Cave Chang Dong are darker, slenderer and having longer antennae than those from caves Jinshi Dong and Gui Dong II. Considering the similarity of male genitalia (Figs. 5a–d), we presume that they are identical. Notes on the type locality. When Uéno & Ran (2001) re-described U. liboensis Deuve et Tian, 1999 , they pointed out that the type locality of this interesting species is probably Cave Bimang Dong instead of Cave Shuijiang Dong cited in the original description ( Deuve et al. 1999 ). According to collecting label, the type locality of U. liboensis is actually Cave Jinshi Dong in the eastern part of Maolan nature reserve, other than either Bimang Dong in the western part, or Shuijiang Dong in the north. However, Uéno & Ran’s species is probably another species, according to their illustration ( Uéno & Ran 2001, p. 14, Figs. 2–3 ), other than U. liboensis because the male genital characters of the individuals collected from caves Pusa Dong (and Dazhu Dong) are so different from those of the holotype specimen. To confirm this it is necessary to visit and collect more material in both above caves which are in central part of Maolan nature reserve and inaccessible. Distribution. China ( Guizhou and Guangxi ) ( Fig. 2 ). Known so far from the bordering karstic areas of Maolan (Libo County) and Mulun (Huanjiang County), both are the World Natural Heritage Sites of Southern China Karsts.
