Material (1 specimen): PEM A14829, camp at side tributary (Luandai River) of the Luanguinga River, -13.70885° 21.26234°, 1,116 m asl. Description: Medium sized Ptychadena ; elongated body; longitudinal dorsal ridges present; long toes; reduced webbing, with up to three phalanges of longest toe free of webbing. Dorsum brown to beige with black and brown spots; black facial mask, from snout through eye to forearm; broad light vertebral band present; thin light line on dorsal tibia; back of thighs with light and dark bands; ventrum light yellow. Only adult male measured 37.7 mm ( PEM A14829). Habitat and natural history notes: Found in grassland alongside a large river during the day. Comments: Identification was based on the key provided by Poynton and Broadley (1985b). Only a few records of this species exist for central and eastern Angola ( Marques et al. 2018). Re-examination of material recorded by Conradie et al. (2016) of Ptychadena guibei also conform to this species.
