Section I: Recognition and Identification of Phlebotomine Sand Flies
Using abdominal tergites for ID
In Phlebotomus, hairs (setae) on the posterior margins of abdominal tergites 2-6 are erect, and their sockets are as large and round as on abdominal tergite 1.
In Sergentomyia, generally, hairs (setae) on the posterior margins of abdominal tergites 2-6 are recumbent. Their sockets are much smaller than on abdominal tergite 1 and they are tear shaped. However, a few Sergentomyia species have erect hairs on abdominal tergites 2-6.
