Trisinus Raffray, 1894 View in CoL

Chinese common name: 幻Ɵà甲¤

Trisinus Raffray, 1894b: 265 View in CoL . Type species: Trisinus cratocerus Raffray, 1894b: 265 View in CoL (designated by Lucas 1920: 657).

= Batrisoplisus Raffray, 1908: 180. Type species: Batrisus antennatus Weise, 1877: 97 (monotypy). Synonymized by Yin et al. 2012c: 62.

Trisinus was synonymized with Batrisoplisus by Yin et al. (2012c), and is currently defined by the presence of an oblique inner pair of carinae on tergite 1 (IV), and the unique form of the aedeagus. The males of most described species have characteristically modified antennae, but the new species described here possesses a modified tergite 2 (V).

The genus is represented by 26 species distributed in Japan (21 spp., including the Ryukyu Islands ), China (3 spp. in Yunnan), Singapore (1 sp.), and Indonesia (1 sp. in Sumatra) ( Newton 2018). The first species from Tibet is described here .
