Description: Medium sized Ptychadena ; elongated body; longitudinal dorsal ridges present; rostrum protruding well beyond lower jaw and forming a very pointed and elongated keratinized protrusion; long toes; reduced webbing, with up to four phalanges of longest toe free of webbing. Dorsum colorful; red infusions on the flanks; black facial mask, from snout through eye to forearm; broad light vertebral band present; thin light line on dorsal tibia; top of thighs with light and dark bands; ventrum immaculate, with black spots on chest in some specimens; black spot in front of arm that connects with lower jaw; lower jaw with spots; back of thighs with irregular longitudinal black and yellow stripes. Adult females (n = 19) varied from 24.6–39.9 (34.8) mm (largest female: PEM A12755); adult males (n = 14) varied from 25.3–31.5 (27.9) mm (largest male: PEM A14894). Habitat and natural history notes: Found in the flooded margins of rivers and lakes. Comments: Originally described from Dala, in north-eastern Angola ( Laurent 1964). It is only known from northeastern Angola ( Laurent 1964; Marques et al. 2018), western Zambia ( Channing 2001), and southwestern DRC ( Channing and Rödel 2019). This is the southernmost record for this species, and a new species record for southeastern Angola and the Okavango River basin.
