Etymology: Apteronotus: Greek, apteros = without wings / (in this cases, fins) + Greek, noton = back (Ref. 45335); acidops: The latinized epithet acidops is compounded by the Greek words akidos meaning "point" and ops meaning "face", referring to the very elongated and pointed head morphology of the species.

ຄີກົ້ນຂອງປາ: 162 - 220. Distinguished from other congeners by the following combination of characters: dorsal snout profile pointed; snout length 46.4 - 63.7 % of head length; oculo-nasal distance 39.2-72.1 % of postocular distance; lateral ethmoid with both dorsal and ventral extremities expanded, strongly oblique in orientation; mouth rictus surpassing vertical through anterior eye margin,
including its skin folds, in all ages; dorsal head profile nearly horizontal from a vertical through anus to posterior extremity of occipital bone; absence of mid-dorsal white or clear stripe on head and body anteriorly; chin brown; upper lip clear to a vertical through anterior nostril; transversal unpigmented bar or bars posteriorly on the body absent; flanks brown, darker
dorsally and pectoral fin hyaline, with chromatophores over rays (Ref. 88927).
Length type refers to length to the end of anal fin, LEA (Ref. 88927).
