Bolivian phlebotomines. II. Psychodopygus yucumensis n.sp., a new man-biting phlebotomine sandfly from subandean region (Diptera, Psychodidae)

Abstract

Psychodopygus yucumensis n. sp., a new species of Phlebotomine sandfly belonging in genus Psychodopygus Mang., is described from specimens collected from human bait, in Beni dept., Bolivia. The male is characteristic of the series panamensis, but the female, closely related to P. carrerai carrerai, can be confused with this species (=cryptic species "). Isozyme characterization can determine any specimen of either species, while morphometric analysis shows statistical differences between the two species.

P. yucumensis is strongly anthropophilic. A Leishmania braziliensis braziliensis stock was isolated from this new species. indicating that it is one of the vectors of mucocutaneous Leishma- niasis in the lowland suhandean area.
