A large (Males 27–32 mm, females 25–36 mm) forest form from R. D. Congo characterised by a less contrasting pattern than in A. equatorialis and especially by its lack of tibial pattern. Dorsum with minute white spots.
The separation of A. leucostictus from equatorialis, the other large forest species in the area, is not well understood. The two forms are generally allopatric and could be regarded as subspecies, but Laurent has reported the occurrence of both species at Sankuru. Although there is considerable overlapping, the snout in
A. leucostictus is generally shorter relative to the eye, and second toe is shorter relative to tibia.
Ventrum in life greyish or violet, not yellowish as in A. osorioi. The gular disc, however, may be yellowish. The dorsal pattern may have quite contrasting colours, but can also be quite uniform with no visible pattern, according to Laurent. Since contrast in pattern in Afrixalus depends very much on light and humidity, and contrast in preserved specimens on the conditions when they were preserved, one can doubt the validity of this as a diagnostic character for the species.
