Siluriformes (Catfishes) >
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); macrostoma: From Greek, makros (big) and stoma (mouth), referring to the large mouth of the species (Ref. 94168). The species name macrostomus (Ref. 58032) is an unjustified emendation, as it is a compound noun and therefore must not agree in gender with the genus name (Ref. 98168).
