Etymology: Gymnelus: Gymnelus, derived from Greek, gymn?los (Latinized Greek) = poor, needy (akin to Greek gymnos for destitute (E. Spencer, pers.comm. 09/13).; diporus: From the Greek word 'diporus', meaning two-pore (Ref. 36338). M.E. Anderson believes this species is probably a synonym of Gymnelus hemifasciatus (Ref. 51665).
