Etymology: Istigobius: Greek, istios = sail + Latin, gobius = gudgeon (Ref. 45335).
Eponymy: Charles Francis Spence (1907–1982) was a businessman in Mozambique, the type locality, whom Smith thanked for providing personal assistance. Spence later published: The Portuguese Colony of Moçambique: an Economic Survey (1951). (Ref. 128868), visit book page.
