The molecular results place the new species within Phrynobatrachus. Morphologically this genus is distinguished from the similar looking and often syntopic Arthroleptis and juvenile Ptychadena by the presence of a tarsal tubercle (absent in Arthroleptis and Ptychadena); presence or absence of webbing (always absent in Arthroleptis); lack of a black spot in the tympanal region (present in Arthroleptis); lack of a median dorsal skin raphe (present in Arthroleptis); and the lack of parallel dorsal ridges (present in Ptychadena). The new species is a small frog (<25 mm) with a short, pointed snout and warty skin; warts most prominent on back; snout-vent length (SVL) of adult males 17.2–20.3 mm, adult females measure 22.5–23.4 mm; mean index head width/SVL is 0.3 (0.3–0.4; N = 17); eyelid tubercles absent; tympanum present but indistinct; fingers without webbing; rudimentary pedal webbing; tips of fingers not or slightly enlarged; toes distinctly enlarged to discs; small inner metatarsal tubercle present, larger than outer metatarsal tubercle; distinct tarsal tubercle; males with a subgular vocal disc, extending to anterior chest, dusted in black or covered with dark black blotches; males with large white ...
