New Cavernicolous Trechine Beetles From Eastern Guizhou Province, China (Coleoptera: Carabidae: Trechinae)

Abstract

 Two new species of cavernicolous trechine beetles falling into a new proposed genus Jiulongotrechus n. gen. and a new proposed subgenus Qiandongaphaenops n. subgen. respectively, are described and illustrated from eastern Guizhou Province, southwestern China. Jiulongotrechus pubescens n. gen., n. sp. is recorded from the cave Jiulong Dong in Tongren City. This new genus is not related to any known trechines occurring in eastern Guizhou such as Qianotrechus Uéno, 2000, Qianaphaenops Uéno, 2000, and Shenaphaenops Uéno, 1999, but somewhat close to Superbotrechus Deuve and Tian, 2009 from western Hubei Province, or Yunotrechus Tian and Huang, 2014 from southern Yunnan Province. Qianaphaenops (Qiandongaphaenops) variabilis n. subgen., n sp. from cave Wanfuchangcheng Dong in Cengong County is set up within the known genus Qianaphaenops Uéno, 2000.
