Description: Small reed frog; sharp but truncated snout, with small to no anterior protrusion; pedal webbing formula: I (1), II i/e (1– 0.5), III (1–0.5), IV (1–1), V (0.75). Dorsum green with white dorso-lateral stripes (mostly males) or uniformly green with scattered brown spots (mostly females); ventrum transparent. Males with yellow gular disc. Single adult female measured 24.7 mm ( PEM A12438); adult males (n = 7) varied from 16.2–22.8 (19.7) mm (largest male: PEM A12440). Habitat and natural history notes: Found on margins of rivers and in wetlands. Restricted to the western side of the study area, associated with the Cubango River system. Comments: In the most recent revision of the Hyperolius nasutus -complex, 16 species have been recognized (Channing et al. 2013). At least four species are expected to occur in Angola (Channing et al. 2013; Marques et al. 2018 ; Baptista et al. 2019 ), namely H. benguellensis , H. nasutus , H. adspersus , and H. dartevellei . Two clear morphotypes exist based on the general snout shape: sharp ( benguellensis group) and rounded ( nasutus group). Of the sharp snouted form, we distinguished between two morphotypes in southeastern Angola : the ‘shark’-like profile ( H. benguellensis , this species account) and the acutely pointed snout, with a distinct protruding tip ( H . cf. inyangae , see species account below). These identifications were confirmed by comparing 16S rRNA barcodes (W. Conradie, unpub. data) to published sequences ( Channing et al. 2012 ). The remaining material is assigned to the nasutus group (see species account below). However, it must be noted that these little green frogs have been the subject of rigorous taxonomic debate over the years due to their cryptic nature, molecular and morphological similarity, and substantial geographic overlaps (see Channing et al. 2012 for overview). The taxonomic status of Angolan species belonging to these groups needs to be assessed in a broad-scale phylogenetic study.
