Diagnosis

Species in the genus Dipsomyia are distinguished from those in Ragas and Zanclotus by the lack of stout setae on postgena and the fore trochanter. The lack of pubescence on the eyes, the setose laterotergite and the isolated prosternum separates the species of Dipsomyia from Hydropeza .

Type species

Dipsomyia spinifera Bezzi, 1909 .
