First record of flesh fly Sarcophaga (Liosarcophaga) aegyptica (Diptera: Sarcophagidae) from India

Abstract

Accurate identification of insect specimens is an essential requirement in forensic entomology. This study aimed to collect adult sarcophagid flies and to identify them based on the male genitalic characters. Its the first report of Sarcophaga (Liosarcophaga) aegyptica from India. The fly has collected, from pig carcasses placed in indoor, outdoor, and aquatic environments during bloated & advanced decay stages of decomposition. The carcasses have placed for decomposition during winter (2015) and spring (2017) seasons in the rural area of Punjab (India). S. (L.) aegyptica belongs to subgenus Liosarcophaga of Superfamily Sarcophagidae, and Salem first reported it from Egypt in 1935. S. (L.) aegyptica is a subtropical thermophilous species that has a wide distribution in the Eastern Hemisphere. The species is infrequent and generally attracted to meat and feces. Their larvae feed and develop on vertebrates carcasses. The species show peculiarity from other species of this genus by the structure of inner forceps of genitalia, which is straight and slightly widened at the subterminal end. Another disparity is in the process of the apical plate of paraphallus, which is pointed at the end. This family has great importance in the field of forensic entomology as they visited immediately on carcasses after Calliphoridae. The fly is of medical importance as these flies are responsible for causing myiasis in humans and animals; hence, they are of medical importance and useful in the estimation of post mortem interval (PMI).
