Hapsidophrys lineatus Fischer, 1856 . Type locality: “ Elmina , Ghana ”.

Gastropyxis orientalis Werner, 1909: 55 . Type locality: “ Deutsch-Ostafrika ”, German East Africa (= Burundi, Rwanda, and Tanzania) .

Distribution. This species extends from Sierra Leona to Uganda, southward to northern Angola. In Equatorial Guinea it has been recorded in Bioko ( Bocage 1895 a, 1903; Drewes et al. 1999) at Ureca ( Mertens 1964a), and in Río Muni at Monte Alén National Park ( Lasso et al. 2002), including Monte Mitra ( Gonwouo & Nsang 2005). There is a record from iNaturalist at Moka, Bioko (03°20′00.04″N, 08°40′20.08″E) ( Map 20C ).

Comments. Martínez y Sáez (1886) and Pérez del Val (2001) recorded H. lineatus based on a misidentification of the specimens MNCN 20286–20289 and MNCN 20290–20293, which are herein reidentified as H. smaragdina . As a result, the first record of H. lineatus for Río Muni corresponds to Lasso et al. (2002). Mertens (1964) reported a case of predation over a juvenile of Amnirana albolabris (Hallowell, 1856) ( Anura : Ranidae ) from Ureca, Bioko.
