Review of the monotypic genus Idiopyrgota Aczel (Diptera, Pyrgotidae)

Aczel established the genus Idiopyrgota to place a single species, I. setiventris, based on an analysis of eight females from Mato Grosso do Sul, Brazil. The species is redescribed on the basis of new available material from the type locality as well as one female specimen from Jujuy, Argentina ( this is the first record of this species in this area). Adult anatomical structures are described and illustrated in detail, including information of the previously unknown male and female spermathecae. This study provides better grounds for the recognition of the taxon.
