The specific diversity of Chinese cave fauna of the ground beetle tribe Trechini is further enriched. Eight new genera and species of trechine beetles are reported from limestone caves in southern China karsts: Youtrechus zijunae n. gen., n. sp. (Xianning, southeastern Hubei Province), Wumengius fengi n. gen., n. sp. (Liupanshui, western Guizhou Province), Chenotrechus parvulus n. gen., n. sp. (Laibin, central Guangxi Zhuang Autonomous Region), Sinaphaenopoides zhaoyiae n. gen., n. sp. (Chenzhou, southern Hunan Province), Ecotrechus ruruiae n. gen., n. sp. Hurites yunxianicus n. gen., n. sp. (Shaoyang, central Hunan Province), Pangaphaenops seraphicus n. gen., n. sp. (Bama, northwestern Guangxi Zhuang Autonomous Region) and Zunotrechus zhaojieyui n. gen., n. sp. (Zunyi, northern Guizhou Province). All the above genera are monospecific. Generic diagnosis of each new genus, with discussions on its possible phylogenetic position within the tribe Trechini, and description of the type species are provided. The following new species of cavernicolous trechines are described: Dongodytes (Dongodytodes) pingjingae sp. n. (Hechi, northern Guangxi Zhuang Autonomous Region), Dongodytes (s. str.) mingruoae n. sp. (Du'an, Hechi, northern Guangxi Zhuang Autonomous Region), Deuveaphaenops (Furongius) huangheae n. sp. (Daozhen, Zunyi, northern Guizhou Province), Shilinotrechus zhangfani n. sp. (Mile, Honghe Hani & Yi Autonomous Prefecture, southeastern Yunnan Province), Guizhaphaenops (s. str.) wanghaoi n. sp. (Qinglong, Qianxinan Buyi & Miao Autonomous Prefecture, southwestern Guizhou Province), and Graciliblemus gui n. sp. (Liping, Qiandongnan Miao & Dong Autonomous Prefecture, southeastern Guizhou Province). Further generic characteristics of the genus Graciliblemus Deuve & Tian, 2016 are added. A distribution map for all above new taxa is given.
中国洞穴步甲族Trechini的物种多样性进一步丰富。在中国南方喀斯特地区的石灰岩洞穴中报道了8个新的Trechini属和物种：紫娟尤特步甲Youtrechus zijunae n. gen., n. sp.（湖北省东南部咸宁市）、冯氏乌蒙步甲Wumengius fengi n. gen., n. sp.（贵州省西部六盘水市）、微小陈氏步甲Chenotrechus parvulus n. gen., n. sp.（广西壮族自治区中部来宾市）、赵氏中华拟暗步甲Sinaphaenopoides zhaoyiae n. gen., n. sp.（湖南省南部郴州市）、如如伊氏艾克步甲Ecotrechus ruruiae n. gen., n. sp.、郧县胡氏步甲Hurites yunxianicus n. gen., n. sp.（湖南省中部邵阳市）、神圣庞氏暗步甲Pangaphaenops seraphicus n. gen., n. sp.（广西壮族自治区西北部巴马县）和赵杰宇氏遵步甲Zunotrechus zhaojieyui n. gen., n. sp.（贵州省北部遵义市）。上述所有属均为单种属。提供了每个新属的属征，讨论了其在Trechini族中可能的系统发育位置，并描述了模式种。描述了以下洞穴Trechini新物种：平靖东洞步甲（东洞步甲亚属）Dongodytes (Dongodytodes) pingjingae sp. n.（广西壮族自治区北部河池市）、明若东洞步甲（东洞步甲指名亚属）Dongodytes (s. str.) mingruoae n. sp.（广西壮族自治区北部河池市都安县）、黄河德氏拟暗步甲（芙蓉拟暗步甲亚属）Deuveaphaenops (Furongius) huangheae n. sp.（贵州省北部遵义市道真县）、张帆石林步甲Shilinotrechus zhangfani n. sp.（云南省东南部红河哈尼族彝族自治州弥勒市）、王浩贵州拟暗步甲（贵州拟暗步甲指名亚属）Guizhaphaenops (s. str.) wanghaoi n. sp.（贵州省西南部黔西南布依族苗族自治州晴隆县）和贵州纤步甲Graciliblemus gui n. sp.（贵州省东南部黔东南苗族侗族自治州黎平县）。补充了2016年Deuve和Tian建立的纤步甲属Graciliblemus的更多属征。给出了所有上述新分类单元的分布图。
