Subgenus Amaroschesis Tschitschérine, 1897

Amaroschesis Tschitschérine, 1897a: 28 [as genus]. Type species: Zabrus chinensis Fairmaire, 1886 View in CoL , designated by Andrewes (1938).

Diagnosis. Differing from Trichotichnus s. str. mostly in metepisternum wider (its anterior margin longer than inner margin) and only slightly narrowed posteriorly. Hind wings highly reduced. Elytra with lateral groove flat throughout or, in some species, with elongate convexity along this groove apically.

Composition. This subgenus comprises about 65 described species from China (Gansu, Shaanxi, Hubei, Sichuan, and Yunnan) .

Remarks. Amaroschesis is morphologically similar to the leptopus group of the nominotypical subgenus ( Kataev & Ito, 1999), and perhaps two these subgenera should be combined ( Ito, 2002b).
