Section I: Recognition and Identification of Phlebotomine Sand Flies

Under the 'scope: Is it a male or female?

The external genital features that are commonly used to separate males are the gonopodites (coxite and style), aedeagus (penis), and parameres.

Over the years, sand fly taxonomists have given the characters of the male external genitalia different names. The superior claspers are also known as the gonopodite. The gonopodite is made of the coxite which is also known as the gonocoxite or the unarmed segment of the superior claspers. The gonopodite is also made of the style which is also known as the stylepodite or gonostyle or the second armed segment of the superior claspers. The style has spines, sometimes referred to as setae, on it and the number and arrangement of the spines can be important for species identification. In summary,
