Male genitalia of flesh fly Parasarcophaga (Liosarcophaga) dux (Diptera: Sarcophagidae) revealed by scanning electron microscopy

Abstract

The male genitalia of flesh fly Parasarcophaga (Liosarcophaga) dux (Diptera: Sarcophagidae) was observed using scanning electron microscopy (SEM). The phallus is a short, broad structure that is formed by a tubular base connected to a trumpet-shaped, anteroventrally expanded ventralia. The juxta projects forward from a broad base, which is connected to an upright long structure, the harpes. The juxta is apically bifurcated. The lateral styli bear three small spines curved inward. The pregonite and postgonite are slightly curved upward apically. The cerci are pointed and curved apically. Sensillae were observed on the surfaces of postgonite, surstylus, epandrium, and cerci.
