Type locality: “ Demerara ” Guyana (in error), corrected to “ Lagos ”, Nigeria by Boulenger (1894) . Ahaetulla lagoensis Günther, 1872: 26 . Type locality: “ Lagos ”, Nigeria . Philothamnus nitidus (Günther, 1863) : Boulenger 1894: 100 . Philothamnus nitidus loveridgei Laurent, 1960: 40 . Type locality: Itula , Shabunda , Kivu , Democratic Republic of the Congo . Distribution . This species extends from Sierra Leone and Guinea to Congo , and southward to Democratic Republic of the Congo and Angola . In Equatorial Guinea it has been recorded in Bioko at San Carlos de Luba [as P. semivariegatus ( Bocage 1895 a , 1903; Loveridge 1958 )] and in Río Muni at Monte Alén National Park ( Lasso et al. 2002 ). Loveridge (1958) suggested that Bocage’s (1895a) record of P. semivariegatus probably belongs to P. s. nitidus (currently P. nitidus ) ( Map 22B ). Comments. Previous reports on P. semivariegatus in Bioko are herein treated as P. nitidus following Loveridge’s (1958) assumption on the identity of the Biokoan population [“ Fernando Po : San Carlos ( Bocage, 1895a : more probably s. nitidus )” fide Loveridge (1958) : 119]. Philothamnus nitidus is the sister taxon to P. angolensis , and both are nested within the paraphyletic assemblage of P. semivariegatus ( Engelbrecht et al. 2019 ) . Specimens examined. Ten specimens.
