Relationships of phlebotomine sand flies (Diptera)

The status of phlebotomine sand flies in relationship to the family Psychodidae (Diptera) is reviewed. It is concluded that sand flies should be given familial recognition as Phlebotomidae, divided into subfamilies Phlebotominae and Bruchomyiinae. A comparison is made between the evolution of Psychodidae and Phlebotomidae, and it is concluded that the two families represent contrasting evolutionary experiments at an early stage of the diversification of Diptera.
