Ptychadena cf. grandisonae Laurent, 1954

Grandison’s Ridged Frog

Material: PEM A11525 (53b).

Comment: A grass frog ( Fig. 9c ) collected on the edge of the upper Longa Riv- er floodplain is tentatively assigned to P. grandisonae . This species has been described from northern Angola (Muita, Laurent 1954) and reported elsewhere in Angola ( Laurent 1964; Poynton and Haacke 1993; Ruas 1996). Although members of the genus Ptychadena are notoriously difficult to identify in museum collections, recent work has shown that species on a regional scale can be distinguished by quantitative morphometrics ( Dehling and Sinsch 2013).
