Hyperolius cinereus Monard, 1937

Ashy Reed Frog ( Fig. 13 ; Map 12 )

Material (12 specimens, 1 tadpole lot): PEM A12442– 4, INBAC (no numbers x 2), Cuchi River gorge, -14.59000° 16.90758°, 1,375 m asl; PEM A12664, PEM A12670, Cubango River, campsite 1 below rapids, west of Fundo village, -13.04790° 16.37806°, 1,565 m asl; PEM A13787–9, INBAC: WC-520, Dam/ Hydroplant on Cuquema River, -12.42556° 16.81856°, 1,640 m asl; PEM A14128 (10 tadpoles), old Kuvango Hydroplant Site, wetland to east, -14.38755° 16.30166°, 1,438 m asl; INBAC: WC-5169, Cubango River source site, -12.66256° 16.09324°, 1,771 m asl. Description: Medium sized reed frog. No sexual dichromatism observed; both sexes with lime green to olive dorsum; protruding yellow eyes; red inner thighs; ventrum yellow. Males with yellow gular disc. Adult females (n = 3) varied from 20.3–29.1 (25.0) mm (largest female PEM A13789); adult males (n = 9) varied from 19.1– 22.8 (21.6) mm (largest male: PEM A12443). Habitat and natural history notes: Only recorded from the western side of the study area, where it was associated with the Cubango and Cuito rivers. Comments: Widely recorded from the interior highlands of Angola ( Conradie et al. 2013). The map in Marques et al. (2018) incorrectly plotted records from southern Cuando Cubango Province. The southeasternmost Angolan record of this species is close to the town of Menongue ( Conradie et al. 2013).
