New data on taxonomy and distribution of several species of ground beetles of the nominotypical subgenus of Trichotichnus Morawitz, 1863 occuring in Yunnan (China) and adjacent areas are provided. Fourteen species are currently recorded from Yunnan. The following new taxa are described: T. (s. str.) angustitarsis sp. n. (western Yunnan, and North West Laos), T. (s. str.) subrobustus sp. n. (northwestern Yunnan), T. (s. str.) schmidti sp. n. (northwestern Yunnan and Nepal), T. (s. str.) fedorenkoi sp. n. (North Vietnam), T. (s. str.) hamulipenis sp. n., with two subspecies: the nominotypical one (northwestern Yunnan) and T. (s. str.) h. nepalensis ssp. n. (Nepal), T. (s. str.) miwai continentalis ssp. n. (southern Sichuan, Yunnan, and North Vietnam), and T. (s. str.) kavanaughi sp. n. (northwesternmost Yunnan). Six species are re-described, with new distributional data. The following species are recorded for the first time: T. (s. str.) doiinthanonensis for China and Vietnam, T. (s. str.) subangulatus for China, and T. (s. str.) fukuharai for the Chinese provinces of Shaanxi and Yunnan. Keys to species similar to T. noctuabundus (the noctuabundus species group) and to Trichotichnus (s. str.) species known from Yunnan are given respectively. Additional justification for the synonymy of T. (s. str.) ellipticus Ito, 2014 [=T. (s. str.) anthracinus Landin, 1955] and T. (s. str.) baehri Ito, 1997 [= T. (s. str.) cyrtops (Tschitschrine, 1906)] is also provided.
提供了关于 occur 在云南（中国）和邻近地区的 nominotypical 亚属 Trichotichnus Morawitz, 1863 的几种地面甲虫的分类和分布的新数据。目前记录了云南的 14 种物种。以下是新描述的分类单元：T. (s. str.) angustitarsis sp. n.（滇西和老挝西北部）、T. (s. str.) subrobustus sp. n.（滇西北）、T. (s. str.) schmidti sp. n.（滇西北和尼泊尔）、T. (s. str.) fedorenkoi sp. n.（越南北部）、T. (s. str.) hamulipenis sp. n.，有两个亚种：指名亚种（滇西北）和 T. (s. str.) h. nepalensis ssp. n.（尼泊尔）、T. (s. str.) miwai continentalis ssp. n.（四川南部、云南和越南北部）和 T. (s. str.) kavanaughi sp. n.（滇西北最西部）。六种物种被重新描述，并提供了新的分布数据。以下物种首次被记录：T. (s. str.) doiinthanonensis 为中国和越南，T. (s. str.) subangulatus 为中国，T. (s. str.) fukuharai 为中国陕西和云南。分别给出了类似于 T. noctuabundus（noctuabundus 物种组）和已知来自云南的 Trichotichnus（s. str.）物种的相似物种的关键。还提供了 T. (s. str.) ellipticus Ito, 2014 [=T. (s. str.) anthracinus Landin, 1955] 和 T. (s. str.) baehri Ito, 1997 [= T. (s. str.) cyrtops (Tschitschrine, 1906)] 同义词的额外理由。
