Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); vanderwaali: Named after the collector of the holotype, Ben van der Waal, in recognition of his donations of fish collections from northern Namibina rivers to the J.L.B. Smith Institute and the Albany Museum (Ref. 26674).
Eponymy: Dr Ben C W Van der Waal was a biologist at the University of Venda for Science and Technology, Thohoyandou, South Africa, which he joined (1986) and was appointed professor (1990). [...] (Ref. 128868), visit book page.
