Etymology: Apterichtus: From the Greek απτερόν (apteron), without fins, and ίχθύς (ichtus, more correctly written ichthys; masculine), fish.
Eponymy: M D Klazinga was the Chief Engineer on board the ‘Siboga’, during the expedition (1899– 1900) on which the holotype was collected. Weber describes him as ‘vaillaint’ (brave), but fails to give his full names. (Ref. 128868), visit book page.
