Sclerophrys gracilipes (Boulenger, 1899) Photo figure 10E

TYPE LOCALITY.— “ Benito River, French (Congo) (sic)”, Río Muni, Equatorial Guinea .

DISTRIBUTION.— Sclerophrys gracilipes is known from West-Central Africa extending from Nigeria to Democratic Republic of Congo and Republic of Congo. Within Equatorial Guinea it has been recorded in Río Muni by Boulenger (1899a) (Type locality: “Benito River”) and De la Riva (1994), and on Bioko by Mertens (1965) (as Bufo funereus gracilipes) and Hydeman et al. (2017) (Map 12A).

COMMENTS.— The molecular phylogeny provided by Liedtke et al. (2016) suggests that this taxon is not monophyletic; thus, a taxonomic revision is in order. As the type locality is in mainland Equatorial Guinea, the specific epithet would be retained for the populations of the clade inhabiting the region of Río Muni and surroundings. On the other hand, populations from Bioko seem to represent a distinct undescribed taxonomic unit (Liedtke et al. 2016).
