Sandfly (Diptera, Psychodidae, Phlebotominae) fauna of South-Western Pakistan. 1. Diagnostic morphology of Phlebotomus papatasi (Scopoli), Ph. bergeroti (Parrot) and Ph. salehi (Mesghali)

A survey was conducted to study the morphology of the sandfly fauna in South-Western Pakistan (Balochistan). During the revision of different genera of sandflies the specimens of Phlebotomus papatasi (Scopoli) (N = 720), Ph. bergeroti Parrot (N = 30) and Ph. salehi Mesghali (N = 70) were encountered in various localities. These localities appear to be new records of the subgenus in the literature to date. Ph. bergeroti is reported for the first time from Pakistan and Ph. salehi from Balochistan as well. Characters of these three Pakistanese Phlebotomus are compared with the published data of these species from other countries. Keys for the identification of Pakistanese Phlebotomus are also constructed. Two female Ph. papatasi collected from indoors out of 132 female flies (1.5%) were found positive with flagellate infection in pharynx and midgut. The possible vectorial role of these flies is also discussed. Further surveys are necessary in parts of the country that have not been systematically surveyed.
