Revision of genus Pericalus from China, with descriptions of four new species (Carabidae, Lebiini, Pericalina)

Abstract

Nine taxa of the genus Pericalus Macleay from China are revised, with four new species described: Pericalus gibbosus sp. n. (type locality: Putao, Myanmar; one paratype from Mêdog, Xizang), Pericalus elegans sp. n. (type locality: Mêdog, Xizang), Pericalus acutidens sp. n. (type locality: Longchuan, Yunnan), and Pericalus obscuratus sp. n. (type locality: Fanjingshan, Guizhou). Four taxa are newly recorded from China: Pericalus ornatus ornatus Schmidt-Göbel (Yunnan, Hainan), P. obtusipennis Fedorenko (Yunnan), P. amplus Andrewes (Yunnan), and P. dux Andrewes (Yunnan). Pericalus formosanus Dupuis is newly ranked as a subspecies of P. ornatus Schmidt-Göbel. An improved key to world species of the subgenus Pericalus is provided, along with distribution maps and images of habitus and male and female genitalia for all Chinese species.
