Description

Arthroleptis variabilis Matschie, 1893 Photo figures 3G–H; 4A–E

TYPE LOCALITY.— “Buea, Barombie, Kamerun”, Cameroon.

DISTRIBUTION.— This species inhabits the lowland rainforest over the Gulf of Guinea region, extending from Nigeria to Gabon, and inward reaching Central African Republic and Democratic Republic of Congo. In Equatorial Guinea, it occurs both in Río Muni and Bioko. Within Río Muni, Arthroleptis variabilis had only been recorded in Monte Alén (De la Riva 1994), while on Bioko it is known from several localities over most part of the island (Bocage 1895a; Boulenger 1900, 1906a; Mertens 1965; Hydeman et al. 2017) (Map 3B).

COMMENTS.— This species has been redescribed by Blackburn et al. (2009). Old highland records from Basilé (2000 m a.s.l) (Bocage 1895a) need confirmation since a newly described congeneric taxon (A. bioko) inhabits the same region at high altitudes. Mraz et al. (2018) reported a case of predation of A. variabilis by an unidentified shrew within a human-mediated trap.
