Bassus Fabricius, 1804 s.s.

Hemiogaster Enderlein 1920, syn. n. The type species, Hemiogaster subrasa Enderlein, 1920, from Sumatra is a new combination in Bassus Fabricius.

Notes.

Used in the strict sense for the species with simple tarsal claws, as was proposed by Sharkey et al. (2009), excluding the species now in Camptothlipsis Enderlein, Lytopylus Foerster and Therophilus Wesmael. The Vietnamese species have the basal half of the second metasomal tergite ivory and the hind tibia black with a pale basal ring (Figs 11, 16, 26). The type species of the genus Hemiogaster Enderlein, 1920, has been examined and proved to belong to Bassus Fabricius s.s. as currently used (Sharkey et al. 2009).
