Section I: Recognition and Identification of Phlebotomine Sand Flies

If a Phlebotomus female, what species might it be?

The Pharynx

The pharynx is an internal structure of the head. It is a posterior continuation of the cibarium and consists of two plates, one dorsal and one ventral. Usually it is bottle or lamp-glass shaped. The base of the pharynx may have spicules, scales, teeth, toothed lines or may be unarmed. Together, all these spicules and teeth are called the pharyngeal armature.
