An annotated list of the genus Chlaenius Bonelli, 1810 (Coleoptera: Carabidae) of Xinjiang Uygur Autonomous Region of China

An annotated list of 14 species of the genus Chlaenius Bonelli, 1810 of the Xinjiang Uygur Autonomous Region of China and adjacent regions is given. Five taxa are newly recorded from China: Ch. (Chlaeniellus) melampus Ménétriés, 1849, Ch. (Ch.) tenui-limbatus Ballion, 1871, Ch. (Achlaenius) tristis tristis (Schaller, 1783), Ch. (Trichochlaenius) steveni (Quensel, 1806), and Ch. (Epomis) circumscriptus (Duft-schmid, 1812). One species, Ch. (s. str.) pallipes (Gebler, 1823), is excluded from the faunal list of Xinjiang, and one species, Ch. (Ch.) nigricornis (Fabricius, 1787), is presumably included in the list. Ch. (Ch.) chrysothorax Krynitzky, 1832 is considered as distinct species, not as subspecies of Ch. kindermanni Chaudoir, 1856. A new synonymy is established: Chlaenius chrysothorax Krynitzky, 1832 = Chlaenius chloodes Andrewes, 1935, syn. n. Chlaenius tristis is trans¬ferred to the subgenus Achlaenius Mandl, 1992 from the subgenus Chlaeniellus Reitter, 1908 on the base of structure of the apical gonocoxite. The re-description of the poorly known Ch. (Chlaeniellus) semenowi Tschitschérine, 1896 is given; its type locality is clarified. The similarity of Ch. (Trichochlaenius) steveni with Ch. (Eochlaenius) suvorovi (Semenov, 1912) is shown based on the structure of the apical gonocoxite. A key to species of the genus Chlaenius from Xinjiang is compiled.
