Distribution in Egypt

provided by Bibliotheca Alexandrina LifeDesk

Nile Valley and Delta. Widespread in the Delta, the Suez Canal zone, Fayoum Depression, and along the entire Nile Valley from Cairo to Aswan. No recent records from the region now inundated by Lake Nasser, although the sp'ecies was reported from that region previously (Marx 1968).The only records outside the general Nile Valley area are two road casualties found in Wadi El Arish, just south of El Arish in North Sinai, on two separate occasions in 1994 and 1996. The species most likely has been acci­dentally introduced with produce or other material originating from the Nile Valley. Similarly a Ptyodactylus hasselquistii population of Nilotic origin was found recently at Zaranik (Baha El Din and Attum 2000).
