Widespread in tropical and subtropical South America, including NE Argentina, Bolivia, Brazil, Paraguay, and Venezuela ( Anzoátegui, Apure, Aragua, Delta Amacuro, Falcón, Guárico, Portuguesa, Sucre, Zulia). Records for Central America and the Caribbean need confirmation. Previously recorded from Venezuela (Apure) by Oliva (2002).

Remarks.

The apex of the median lobe is a fine membranous dome, which may be considerably deformed in dry-mounted specimens. See discussion of Berosus megaphallus sp. n.
