Abstract: Three species of fleas in Ceratophyllidae were studied. They include Syngenopsyllus cacceatus, Macrostylophora euteles and Monopsyllus anisus. The lateral, dorsal and ventral sides oftheir phallosomes were observed with light and scanning electron microscopes. There are a pair of C-sclerite and a pair of iverticulum at the base of aedeagal pouch in S. calceatus. In M. euteles there is a pair of aubergine-shaped sclerite. The apex of the aedeagal crochet is divided into dorsal and ventral lobes. The anterior end of the aedeagal apoderne is different from its specialized posterior end. The paxillus of these three species is in the shape like ox horn and protrudes anteriorly, the taxonomic characteristics in these three species are discussed, his suggested that the penis rods slide between the median and lateral laminae during copulation.
