Abstract
Eleven new species of the Tachinus nepalensis Ullrich group of the subgenus Tachinoderus Motschulsky are described from China, Vietnam and Laos: T. asperius Chang, Li & Yin, sp. nov. (Yunnan), T. biangulatus Chang, Li, Yin & Schülke, sp. nov. (Shaanxi, Sichuan), T. bimorphus Chang, Li, Yin & Schülke, sp. nov. (Yunnan, Xizang), T. breviculus Chang, Li, Yin & Schülke, sp. nov. (Sichuan, Yunnan), T. chengzhifeii Chang, Li, Yin & Schülke, sp. nov. (Shaanxi, Zhejiang, Hubei, Fujian, Guangxi, Chongqing, Sichuan, Yunnan, Vietnam: Sa Pa), T. granosus Chang, Li, Yin & Schülke, sp. nov. (Shaanxi, Gansu, Sichuan), T. maculosus Chang, Li, Yin & Schülke, sp. nov. (Yunnan), T. meniscus Chang, Li, Yin & Schülke, sp. nov. (Hunan, Guangdong, Guangxi, Yunnan), T. qian Chang, Li & Yin, sp. nov. (Guizhou), T. songxiaobini Chang, Li & Yin, sp. nov. (Yunnan), and T. yunnanensis Chang, Li, Yin & Schülke, sp. nov. (Yunnan; Laos: Phongsaly). Main characters distinguishing species are the shapes of the terminal tergites and sternites of both sexes, and morphological differences in the aedeagi. New collecting data for eight known species: T. beckeri Ullrich, T. grandicollis (Bernhauer), T. laosensis Katayama & Li, T. naomii Li, T. nigriceps Sharp, T. pseudobirmanus Schülke, T. sugayai Schülke and T. yushanensis Campbell are given. Tachinus laosensis Katayama & Li is recorded from China for the first time. An identification key to and distributional maps of the Chinese species of the T. nepalensis group are provided.
