Ptychadena neumanni (Ahl, 1924)

Class: Amphibia > Order: Anura > Family: Ptychadenidae > Genus: Ptychadena > Species: Ptychadena neumanni

Rana neumanni Ahl, 1924, Mitt. Zool. Mus. Berlin, 11: 4. Syntypes: 35 syntypes noted in original publication; apparently including ZMB 26879 (3 specimens), and MCZ 22331-32 (according to Barbour and Loveridge, 1946, Bull. Mus. Comp. Zool., 96: 184). Restricted to ZMB 26879 (3 specimens) by inference of restricted type locality and action of Largen, 2001, Tropical Zool., 14: 340. Type locality: "Didda", "Somaliland", "Gadat (Gofa)", and "Ufa"; restricted to "Gadat (Gofa), Sud Ethiopia" by Perret, 1980, Monit. Zool. Ital., N.S., Suppl., 13: 157. Largen, 2001, Tropical Zool., 14: 340 noted that ZMB 26877 and 26878A-T are referrable to Ptychadena nana.

English Names

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

Neumann's Grass Frog (Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 189).

Distribution

Ethiopian Plateau, 820-3800 m elevation. See comment below regarding the ranges of the various unnamed lineages within this complex. 

Comment

See comment under Ptychadena nana. Largen, 2001, Tropical Zool., 14: 338–339, discussed distribution and the difficulty in separating Ptychadena erlangeri and Ptychadena neumanni by external morphology alone. See discussion by Largen, 2001, Tropical Zool., 14: 340–342. See account, photograph, and map for Ethiopia by Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 188–190, who suggested that this name represents a complex of species of which Ptychadena largeni is only questionably separated. Freilich, Tollis, and Boissinot, 2014, Mol. Phylogenet. Evol., 71: 157–169, presented molecular evidence that nominal Ptychadena neumanni is composed of at least five species, two of which (sp. 2 and 3) form the sister taxon of Ptychadena erlangeri, one of which is the sister taxon of that group (sp. 4), another that is the sister taxon of that inclusive group (sp. 1), and a fifth (sp. 5) that is the sister taxon of Ptychadena cooperi. This overall complex surrounds Ptychadena nana phylogenetically as well. Geographically they are known definitively from: 1: moist evergreen forests of the southwest to the grasslands in the vicinity of Addis Ababa; 2: widely distributed on both side of the Great Rift and limited to grasslands; 3: Bale Mountains; 4: southern part of the Eastern Highlands; 5: western highlands, north of the Blue Nile Valley.
