Sclerophrys latifrons ( Boulenger, 1900) Photo figure 10F

TYPE LOCALITY.— “ Benito River ”, Río Muni, Equatorial Guinea .

DISTRIBUTION.— It inhabits dense and high tropical forests over the Gulf of Guinea region from Cameroon to Gabon and Congo, extending to the Democratic Republic of Congo. In Equatorial Guinea S. latifrons has been recorded in Río Muni (where the type locality is: “Benito River”) ( Boulenger 1900; De la Riva 1994) and on Bioko ( Boulenger 1906a) ( Map 12B ).

COMMENTS.— The record of Bioko is doubtful. Despite the efforts to sample amphibians from Bioko, S. latifrons has not been recorded from the island since Boulenger (1906a). This species has been included in a recent molecular phylogeny ( Liedtke et al. 2016). However, the phylogeographic structure across most of its range, including the Equatorial Guinean populations, remains unknown. The record identified as “ Bufo maculatus ” from Monte Mitra at Monte Alén National Park (Gonwouo and Nsang 2005) likely belongs to S. latifrons .

SPECIMENS EXAMINED.— Eight specimens. Miboman, Bata-Movo (Km 27), 24 June 1984 ( EBD 18601 ); Miboman-Movo-Bata (Km 27), 05 October 1984 ( EBD 18253 ); Guinea Ecuatorial ,

without precise locality (four specimens, three of them with the label EBD 27844 , 27839 , 27846 ); Miboman, 01 September 1984 ( EBD 18283–18284 ) .
