Keywords: diversity, karst, morphology, taxonomy

Abstract

Eleven new species of Tyrannochthonius from Guangxi Province in southern China are described, including detailed diagnosis and illustrations: T. baiseensis sp. nov. from Dayan Cave (Lingyun County), T. fenghuangensis sp. nov. from Unnamed Cave 3 (Bama Yao Autonomous County), T. laqiuensis sp. nov. from Laqiu Cave (Donglan County), T. longulimembrum sp. nov. from Guangyang Cave (Tiandong County), T. miridentatus sp. nov. from Xi’an Cave (Fengshan County), T. shenlongensis sp. nov. from Shenlong Cave (Huanjiang Maonan Autonomous County), T. xianguensis sp. nov. from Xiangu Cave (Yizhou District), T. xiannvyanensis sp. nov. from Xiannvyan Cave (Yizhou District), T. xiaoi sp. nov. from Unnamed Cave 1 (Xing’an County), T. yilingyanensis sp. nov. from Yilingyan Cave (Wuming District) and T. yui sp. nov. from Unnamed Cave 2 (Yufeng District). An identification key to all known species of Tyrannochthonius from China is also provided.
