Distribution. This species extends from Gambia to Uganda, and southward to northern Angola. In Equatorial Guinea it has been recorded in Bioko (Boulenger 1894) at San Carlos and Natividad (Hacienda Natividad) (Bocage 1895 a, 1903; Mertens 1964a) and in Río Muni at Cabo San Juan (Boulenger 1905) and Monte Alén National Park (Lasso et al. 2002), including Monte Mitra (Gonwouo & Nsang 2005) (Map 21A).
Comments. One of the commonest snake species in Río Muni. The specimens erroneously recorded by Martínez y Sáez (1886) and Pérez del Val (2001) as H. lineatus (MNCN 20286–20289 and MNCN 20290–20293) are herein regarded as H. smaragdina .
