Sclerophrys tuberosa (Günther, 1858) Photo figures 11C–E

TYPE LOCALITY.— “ Fernando Po ”, Bioko , Equatorial Guinea.

DISTRIBUTION.— It occupies the tropical forest of the Gulf of Guinea region from Cameroon to Gabon, Congo and Democratic Republic of Congo. In Equatorial Guinea, this species occurs both on Bioko and in Río Muni. Within Bioko it has been recorded from several localities ( Mertens 1965; Boulenger 1900), while it is only known from two localities in the continental region of Río Muni ( Boulenger 1903; De la Riva 1994) ( Map 13A ).

COMMENTS.— Populations from Río Muni appear morphologically different from those on Bioko and in Cameroon. Phylogenetic relationships within the genus were studied by Liedtke et al. (2016) based on molecular data.

SPECIMENS EXAMINED.— Twelve specimens. Nvom (Aconibe-Asoc), 08 May 1987 ( EBD 25026 ) ; Acocnseng (Km 10 Aconibe-Asoc), 30 May 1987 ( EBD 25027 ) ; UPM camp-Riaco river, Caldera de Luba , Bioko, 03°20ʹ46.54ʺN, 08°29ʹ48.20ʺE, 14 December 2005 ( MNCN 46709– 46710 , 46712 ), 13 December 2005 ( MNCN 46711 ) ; Moaba , Bioko, 03°14ʹ01.41ʺN, 08°37ʹ19.64ʺE, 21 November 2003 ( MNCN 48870 ) ; top of trail into Caldera de Luba , Bioko, 3°20ʹ5.02ʺN, 8°29ʹ14.33ʺE, 26 November 2003 ( MNCN 48871–48873 ) ; surroundongs of BBPP camp, 03°20ʹ47.32ʺN, 08°29ʹ48.44ʺE, 26 and 27 November 2003 ( MNCN 48874–48875 , respectively) .
