Diagnostic characters. This species belongs to the group III of Megaselia ( Borgmeier 1962) . It is easily distinguished from other group III species by its thickened costal vein and lacking vein r2 +3.

Distribution. Southern Brazil.

Updated distribution for Brazil. Rio Grande do Sul and Santa Catarina.
