Additional material (4 tadpole lots): SAIAB 209127 (1 tadpole), SAIAB 209107 (2 tadpoles), swamp near Cuanavale River lake camp, -13.10750° 18.86089°, 1,386 m asl; SAIAB 209108 (22 tadpoles), pool in wetland on road edge west of Munhango, -12.17806° 18.24306°, 1,381 m asl; SAIAB 209089 (4 tadpoles), Calua lagoon, -12.73599° 18.39394°, 1,448 m asl. Description: Large sized Kassina; tympanum visible; elliptical vertical pupils; large inner metatarsal tubercle; subarticular tubercle well-developed. Dorsum very dark olive-brown, with scattered large darker brown yellow-edged irregular shaped spots; ventrum yellow, but in some individuals has black-edged white/yellow spots. In females, the cloaca sides are swollen. In males, the gular flap is dark and the glands behind eye/head are enlarged. Adult females (n = 2) varied from 51.9–53.3 (52.6) mm (largest female: PEM A14096); adult males (n = 7) varied from 38.4–52.9 (43.7) mm (largest male: PEM A12781). Tadpoles can get very large (up to 135 mm total length); LTRF 1/2(1), with strong jaw sheaths. Habitat and natural history notes: In the evenings, males call from the margins of source lakes and flooded areas while clinging to vegetation, and quickly submerge themselves when disturbed. Comments: These new records and other records from Uíge Province, which are the northwesternmost records (Ernst et al. 2020), represent the first adult K. kuvangensis for Angola since the original species description (Monard 1937). The new localities recorded here lie between the species type locality in Angola (Kuvango, Monard 1937) and western Zambia (Poynton and Broadley 1987, 1991; Channing 2001).
