Description: Medium sized reed frog; rounded snout; reduced webbing; ventrum granular. Three different color forms were observed, i.e., plain light to dark green, brown, and bright red; thin dorsolateral white stripe present; small white specks on dorsal side of legs; toes and webbing red. Tadpoles with ventrum spotted and ventral blotches remain present in juveniles but fade in adults. Adult females (n = 11) varied from 16.7–21.9 (19.6) mm (largest female: PEM A12549); adult males (n = 52) varied from 14.8–21.1 (18.7) mm (largest male: PEM A12592). Habitat and natural history notes: Found at the margins of large rivers and source lakes within dense emergent wetland vegetation. Sympatric with other species of Hyperolius , mostly H. nasutus and H. parallelus . Comments: Initially we assigned these specimens to H. bocagei (NGOWP 2017) , however it is generally regarded as a larger species that is associated with the viridiflavus group (see Schiøtz 1999). This new material differs in size (smaller) and webbing (less webbing) from H. bocagei ( Schiøtz 1999) . Phylogenetic work is currently underway to determine its taxonomic status.
