Abstract

The capture of a new species of the subgenus Migonemyia Galati, 1995 (Diptera, Psychodidae, Phlebotominae), Migonemyia vaniae sp. nov. in the Ribeira Valley, state of São Paulo, Brazil, together with the other two species: Mg. migonei (França, 1920) and Mg. rabelloi (Galati & Gomes, 1992) lead us to review this subgenus. The new species was described and illustrated. The genitalia of the two other species were also illustrated and some genital characteristics (number of setae on the gonocoxite tuft, ejaculatory ducts and pump and ducts/pump ratio; and number of setae on the tergite VIII of the females) considered important to differentiate the three species, including five populations of Mg. migonei (from Northeastern, Southeastern, and Southern Brazilian regions and of Peru) were submitted to variance analyses. The Mg. migonei population of Northeastern Brazilian region showed distinct smaller values (P< 0.05) than the other Brazilian populations studied as regarding these characteristics. The capture of both sexes of these three species in sympatry confirms the association between the sexes of Mg. rabelloi, recognised as doubtful when this species was originally described. Identification keys for male and female of the three species are presented.
