Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335); petersi: The species name petersi is given in honour of the German herpetologist Wilhelm C.H. Peters who had carried out a major fish survey of the lower Zambezi region, and discovered many of the endemics and other widespread species during his 'Naturwissenschaftliche Reise nach Mossambique 1842-1848' (Ref. 91771).
Eponymy: Wilhelm Karl Hartwig Peters (1815–1883) was a German zoologist and traveller who made some very important collections in Mozambique. [...] (Ref. 128868), visit book page.
