Abstract

Two highly modified new species of cave-adapted trechine beetles are described from Guizhou Province and Guangxi Zhuang Autonomous Region: Sinaphaenops (Sinaphaenops) chengguangyuani n. sp. (Guizhou: Longli: cave Shuijing Dong), belonging to the banshanicus species group of the genus Sinaphaenops Uéno & Wang, 1991; Giraffaphaenops brevicephalus n. sp. (Guangxi: Leye: cave Dalongguan Dong), being the third species of the genus Giraffaphaenops Deuve, 2002, with a shorter but broader head than its congeners. Keys to identify the species of the banshanicus species group and the genus Giraffaphaenops are provided respectively.
