Cornutrypeta Han et Wang, 1993

Cornutrypeta Han et Wang, 1993: 169 . Type species: Trypeta superciliata Frey, 1935, by original designation.

Diagnosis. Cornutrypeta is a sexually dimorphic genus. The generic diagnosis is only available for males, with the females being almost impossible to separate from those in the closely related genus Trypeta Meigen. Males differ from other Oriental and Palaearctic Trypetinae genera by the following combination of characters: (1) 3-5 frontal setae with at least 2 anterior ones greatly enlarged among remaining normal setae; (2) frons enlarged to accommodate the extensive elaboration of the anterior frontal setae; (3) glans with median granulate sclerite large, apicodorsal rod usually present (Han et al., 1993).

The larvae of Cornutrypeta spinifrons (Shroeder) have been reported from Europe to mine the leaves of Solidago vergaurea and Aster sp. ( Asteraceae) (White, 1988; Han et al., 1993). This is the only biological information available for the genus.

With the addition of 2 new species described below, 14 species of this genus are recorded from the Palaearctic and Oriental regions, 12 of which occur in China.
