Abstract

The Pterostichus pulcher species group of the subgenus Orientostichus Sciaky & Allegro is defined for P. pulcher Sciaky & Allegro and six new allied species. All seven species of this group are revised on morphological characters. Six new species are described from south of Sichuan province, China: P. pemphissp. nov. (type locality: Shuihaizi, Puge county, 27.33°N, 102.45°E), P. orbicollissp. nov. (Longzhoushan, Huili county, 26.79°N, 102.20°E), P. leosp. nov. (Shizishan, Jinyang county, 27.88°N, 103.23°E), P. liyuanisp. nov. (Luojishan, Puge county, 27.58°N, 102.39°E), P. condylussp. nov. (Yele, Mianning county, 28.96°N, 102.16°E), P. jialinisp. nov. (Jiamashi, Huidong county, 26.81°N, 102.68°E). Tritrichis chinensis Jedlička, syn. nov., a species previously misplaced in the subgenus Orientostichus, is excluded from the genus Pterostichus and confirmed to be a junior synonym of Synuchus nitidus reticulatus Lindroth, 1956.
