Genus Cyclosomus Latreille, 1829

Scolytus Fabricius, 1790:221, in part [junior homonym of Scolytus Geoffroy, 1762] (type species Carabus limbatus Fabricius, 1801, designated by Latreille (1810:426)). Fabricius (1792:180); Bousquet (2012:89). Cyclosomus Latreille, 1829:394 (type species Carabus flexuosus Fabricius, 1775, by monotypy).

Diagnosis. Adults of Cyclosomus can be distinguished from those of Tetragonoderus species in the study area by the following combination of character states: Body size larger, BL = 7.0 mm or more; pronotum (Fig. 13A) very broad, trapezoidal, almost as wide as elytra at humeral angles, distinctly widest at base; elytra broadly rounded apically, elytral color pattern as in Fig. 7A; front tarsomeres 1 to 3 markedly expanded laterally (Figs. 14A, 15A) in both males and females.

Diversity: At present, only five species are recognized in the Asian fauna, and here we record one, a new species, from the study area.
