Description

provided by AmphibiaWeb articles
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.This account was taken from "Treefrogs of Africa" by Arne Schiøtz with kind permission from Edition Chimaira (http://www.chimaira.de/) publishers, Frankfurt am Main.

Afrixalus leucostictus

provided by wikipedia EN

Afrixalus leucostictus is a species of frog in the family Hyperoliidae.[1][2][3][4] It is endemic to eastern and central Democratic Republic of the Congo.[1][2] Its relationship with Afrixalus equatorialis is not fully understood.[1][3][4] Common names Makese banana frog and speckled spiny reed frog have been proposed for it.[2]

Description

Adult males measure 27–32 mm (1.1–1.3 in) and adult females 25–36 mm (1.0–1.4 in) in snout–vent length. The snout is relatively short. The dorsal pattern varies from nearly absent to quite contrasting, but less so than in A. equatorialis (notice that the contrast is known to vary with light and humidity). The ventrum is greyish or violet; the gular disc might be yellowish. The tibia lack pattern.[3][4]

Habitat and conservation

Afrixalus leucostictus inhabits in dense forests at elevations of 750–1,000 m (2,460–3,280 ft) above sea level. It is associated with stagnant pools, its presumed breeding habitat.[1]

A. leucostictus is a poorly known but widely distributed species. It is not threatened overall, although local populations probably suffer from habitat loss caused by agricultural encroachment, expanding human settlements, and wood extraction. It is present at least in the Virunga National Park.
