Material examined of Protidricerus palliventralis new synonym. Holotype. ♂, China, Fujian Sangang, 24. VIII. 1986, Jiashen Wang, CAUN 200330.

Distribution. China: Zhejiang, Fujian, Guangxi, Sichuan, Guizhou, Tibet; India, Burma, Pakistan.

Remark. McLachlan (1891) published a new species, Idricerus elwesii , based on a female from Indien: Assam. Weele (1908) moved it to his new genus Protidricerus and redescribed this species. But he didn’t examine the male specimen of P. elwesii . The original description of P. palliventralis is based on a male collected from Fujian, China. We examined 42 specimens (21♀, 21♂) collected from six provinces of China including Tibet. We determined that all male specimens were P. palliventralis , whereas all female specimens were P. elwesii . We therefore deduce that P. palliventralis is a junior synonym of P. e l w e s i i.
