Figure 21A–B

Dendrophis flavigularis Hallowell, 1852: 205 . Type locality: “ Gabon ” [Loveridge (1944) corrected the type locality to Gabon, originally given as “ Liberia, Western Africa”].

Thrasops flavigularis (Hallowell, 1852): Hallowell 1857: 67.

Hapsidophrys niger Günther, 1872: 25 . Type locality: “Gaboon”.

Thrasops pustulatus Buchholz & Peters, 1875 in Peters (1875): 199. Type locality: “Cameruns; Mungo”.

Distribution. It extends from Nigeria to the Democratic Republic of the Congo, south to northern Angola. In Equatorial Guinea it has been recorded both in Bioko at Moka (Boulenger 1906; Loveridge 1944; Capocaccia 1961a; Mertens 1964a) and in Río Muni at Cabo San Juan (Boulenger 1905) and Monte Alén National Park (Lasso et al. 2002) (Map 23C).

Comments. The record of Dispholidus typus of Pérez del Val (2001) labelled as MNCN 19977, is a misidentification with a juvenile of T. flavigularis (Figure 21B). Because no confirmed records of D. typus exist in Equatorial Guinea, we remove it from the reptile species list of the country.
