Auchenoglanididae (Flatnose catfishes)
Etymology: Notoglanidium: Greek, noton = back + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish; diminutive (Ref. 45335); akiri: Named in honour of P.J. Akiri, collector of the type specimens (Ref. 94168).
Eponymy: Pamela Jeanne Akiri (b: 1944) is an American biologist who moved to Nigeria with her husband and worked at Rivers State University of Science and Technology, Port Harcourt, Nigeria. She collected the catfish holotype. (Ref. 128868), visit book page.
