A large Afrixalus (Males 28–34 mm, females 32–35 mm) from bushland in Cameroun and easternmost Nigeria. Pattern in dark brown and silverish similar to that of A. nigeriensis but with the dark middorsal band never cut straight off anteriorly and with light dorsolateral bands only sometimes confluent middorsally. Tibia with two light spots.
This species has previously been regarded as a subspecies of A. osorioi, but is nowadays regarded as a full species.
According to Amiet (1975), populations from Mt. Manengouba, Cameroun differ from the widespread populations on the plains. The form from Mt. Manengouba is smaller, the head narrower and the dark dorsal pattern reduced to a short ”exclamation mark”, or the dorsum is completely white. This population may deserve subspecific recognition or it may be regarded as an aberrant population, as is sometimes found in other Afrixalus.
The tadpole of A. paradorsalis has not been described.
The voice of A. paradorsalis is quite different from the voices of the other large Afrixalus. It consists of two, sometimes three clicks, rather than the long series in the other members of the genus.
