Phrynobatrachus cornutus ( Boulenger, 1906)

TYPE LOCALITY.— “Zima” (= Sangmelima), Cameroon .

DISTRIBUTION.— Phrynobatrachus cornutus is distributed from Cameroon to western Republic of Congo, Gabon and Central African Republic. In Equatorial Guinea, it has been recorded from Río Muni at Monte Alén (as Phrynobatrachus sp. of the P. cornutus group; De la Riva 1994) and from Bioko at several localities ( Mertens 1965; Zimkus 2009; Hydeman et al. 2017) ( Map 22C ).

COMMENTS.— There is no deep phylogeographic structure between Bioko and Cameroonian populations, which are part of the same lineage (authors’ unpublished data). The populations reported from Río Muni are morphologically similar to P. mayokoensis (authors’ pers. obs.), but additional studies are needed to confirm its systematic relationships and taxonomic identity.

SPECIMENS EXAMINED.— Six specimens. Forest close to Illadji River, Bioko , 03°19ʹ46.04ʺN, 08°40ʹ26.13ʺE, 14 November 2003 ( MNCN 48885–48887 ) ; Rio Lukuele, on the way from Belebu to Ureka , Bioko , 03°24ʹ25.81ʺN, 08°33ʹ3.23ʺE, 20 November 2003 ( MNCN 48888 ) ; casa Moraka, 9 km west of Ureka, Bioko , 03°15ʹ33.05ʺN, 08°29ʹ11.18ʺE, 24 November 2003 ( MNCN 48889 ) ; path behind church, Bakelele forest, Batete, Bioko , 03°26ʹ37.34ʺN, 08°30ʹ24.76ʺE, 02 December 2003 ( MNCN 48890 ) .
