English Names

Somali Grassland Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 105).

Smallest Grass Frog (Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 191).


Known only from two localities (the holotyep from 2000–3000 m for the holotype and 3800 m for the second specimen) in the Arussi Mountains of the Ethiopian highlands east of the Rift.


Holotype originally in syntypic series of Ptychadena neumanni according to Borkin, 1985, In Frost (ed.), Amph. Species World: 473. Largen, 2001, Tropical Zool., 14: 339–340, commented on distribution and difficulty in identification. See account and map for Ethiopia by Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 191, for this species that had not been collected since 1900. Böhme and Rödder, 2011, North-west. J. Zool., 7: 322–324, reported an additional specimen from the Arussi Mountains but did not report on when it was collected or by whom, which leaves big questions about the fate of this species and how long it has been since last seen (DRF). The authors also discussed a possible unnamed species in Bale National Park, Ethiopia.
