Distribution. It occurs both in the eastern Mediterranean and in African regions south of the Sahara Desert. In the Mediterranean it ranges along the eastern coastal areas, from Turkey to Israel, whereas in Africa it extends from West Africa to East Africa, southwards to the north of Namibia and northwards to Egypt (Nile River). In Equatorial Guinea it has been recorded from Río Muni at Monte Mitra in Monte Alén National Park (Gonwouo & Nsang 2005) and also it is expected to be found close to the Cameroonian border (Campo River) (Rhodin et al. 2017) (Map 3B).
Comments. The current known record of this species is based on a single specimen from Monte Mitra (Gonwouo & Nsang 2005).
Specimens examined. No specimens of this species were found in the examined collections.
