title: Geographical distribution of the subgenus Helcocyrtomyia, genus Lutzomyia (Diptera: Psychodidae--Phlebotominae).
abstract: The known geographical distribution of species included in the subgenus Helcocyrtomyia Barretto is reviewed. It is suggested that the vexator series of the subgenus originated in the Nearctic Region and extended southwards along the Andes (peruensis series) whereas the oswaldoi series is a South American assemblage originating in Gondowana. It is concluded that Helcocyrtomyia cannot be accepted as a monophyletic group.
