Leptopelis occidentalis Schiøtz, 1967
EOL Text
A rather large forest-dwelling Leptopelis (males 38-43 mm, females 71 mm) from West Africa. Phase A green, uniform or with minute white spots. Phase B, dorsum brown with a darker n-shaped pattern, in some cases as a triangle with the apex pointing forward.Among the West African forms L. occidentalis is larger and better-webbed than L. hyloides (and the doubtful L. bequaerti), smaller and less webbed than L. macrotis.
This form is similar to the Cameronese L. boulengeri, and may be related. It differs in its pattern, L. boulengeri having a pointed dark apex in most specimens, occidentalis rarely so, and by its very different voice. A few specimens have been collected in western Nigeria. It cannot be decided whether they belong to this species or to boulengeri.

This species occurs in Liberia, southern Côte d’Ivoire and central Ghana. It possibly ranges as far east as Nigeria and its western limits in Liberia are unknown. There are records from western Nigeria, but it is unclear if it is this species (M.-O. Rödel pers. comm. June 2012). It is found from approximately sea level to 200 m asl. It is quite well surveyed and the range is well documented; it is therefore unlikely to occur in other areas (M.-O. Rödel pers. comm. June 2012). It is known from numerous sites. Although its range covers a large area (ca 146,698 km2), its area of occupancy (AOO) based on a 4 km2 cell is estimated to be 176 km2 (J. Penner pers. comm. September 2013).

A forest species, frequently heard and apparently widely distributed in West Africa, but difficult to collect. The species is known from Liberia to Ghana, possibly to Nigeria.

Quite often a small number of males could be heard calling together rather high up in bushes and trees. Several were heard calling from large clumps of bamboo. The voice is a rather soft "düt" with a very peculiar acoustical quality. The sonogram shows a voice with a large number of harmonics about 300 cps. apart.

Its natural habitats are subtropical or tropical moist lowland forests, rivers, and intermittent freshwater marshes. It is threatened by habitat loss.
