Species Description: Plath M, Herrmann H-W, Bohme W 2006 New frog species of the genus Phrynobatrachus (Anura:Phrynobatrachidae) from Mt. Nlonako, Cameroon. J Herpetol 40:486-495
Coloration: Head is dark brown to black; dorsum, outer upper arms (and lower arms in females), and outer side of legs are olive green-brown; ventrum and inner legs are beige to yellowish white. Distinguishing characteristics include spotted white lips and a distinct white band between the eyes, in various forms (solid, dashed, linear, triangular). White spots also cover forelegs and flanks. Tibia decorated by one to two medium size bars or large spots.
Males differ from females in that the white spots from the lips continue to the tympanum and in darker coloration of the tympanum, forearms, back of neck, and throat. In contrast, females have black spots on the green-brown forearms and are lighter in coloration on the ventrum, gular region, and forelegs.

Arthroleptis nlonakoensis was originally placed in the genus Phrynobatrachus. However in 2008, Fretey reviewed morphological differences in the two genus and placed the species within Arthroleptis. This was further supported by Zimkus and Larson (2009) based on direct measurements of A. nlonakoensis specimens.
