Identification Both Tympanopleura and Ageneiosus do not have obvious, permanent barbles. The two genera can be externally distinguished in that Tympanopleura has a prominent pseudotympanum consisting of an area on the side of the body devoid of epaxial musculature where the gas bladder contacts the internal coelomic wall; are shorter, blunter headed without greatly elongated jaws; and have a smaller adult body size.

This species is commonly misidentified as A. vittatus. A. sp. (3) has a much more flattened head (A. vittatus' head looks more rounded like A. magoi). A. sp. (3) lacks the typical mottled colouration of A. vittatus (similarity in pattern is said to be superficial) and A. sp. (3) lacks the two very prominent caudal fin spots (one on each lobe) of A. vittatus.
Sexing Like all Auchenipterids, males have a genital papilla. Moreover, sexually active males get an enlarged and slightly curved dorsal spine and thickened barbels, that are used to clasp the female. After the breeding season, the dorsal spine and the barbels grow back to their normal sizes.
General Remarks One of the smaller ageneiosids.
