Genus Hydropeza Sinclair, 1999

Figs 3 , 7B, 7 E–F, 9 C

Diagnosis

The species in the genus Hydropeza resemble those of Dipsomyia by lacking the stout setae on the postgena, and the fore trochanter that is present in species in the genera Ragas and Zanclotus . Species in Hydropeza are distinguished from those in Dipsomyia by having pubescent eyes, a bare laterotergite, and a prosternum that is fused with the proepisternum and forming a precoxal bridge.

Type species

Trichopeza longipennae (Miller, 1923) .
