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, even though reported as locally abundant in the IUCN Red List account from 2013. 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. The authors also discussed a possible unnamed species in Bale National Park, Ethiopia, which seems to be have been considered by the IUCN Red List as Ptychadena nana
