This species is known only from the northern Rift Valley of Ethiopia, at 700-1,585 m asl, where it has been recorded from two localities: Lake Langano, and the Awash National Park. Its distribution is not typical of an endemic species to Ethiopia, and M. Largen (pers. comm.) considers that it might be found to occur in Eritrea and Somalia. However, M. Tandy (pers. comm.) thinks that it might be more restricted, and that the two known populations might belong to different species (in which case their ranges should not be joined, contrary to what has been done in attempts to map their distribution for this assessment).
Habitat and Ecology
It is associated with permanent water in arid savannah and semi-desert country. It has been found in and around small lakes, stream-fed pools, irrigation ditches, and large freshwater (non-alkaline) lakes, in a general landscape ranging from a sub-desert steppe of volcanic rubble, xerophilous grasses and thorn scrub, to heavily grazed Acacia savannah. It breeds by larval development in permanent lakes and pools.
This species was found to be reasonably numerous at both the type locality (Lake Langano) and in the Awash National Park during the 1970s. There has been little recent survey work within its range.
The main threats to this species are environmental degradation and water pollution, resulting from urban expansion and human settlement, agricultural encroachment, and increasing numbers of domestic livestock. However, this species might well benefit from irrigation schemes on the Awash River, which could increase the availability of suitable habitat.
The only protected area in which it is currently known to occur is Awash National Park. Research is needed on its taxonomy, distribution and population status.
It is possible that this name covers two species (Tandy pers. comm.).
