Transliterated from the Greek tympanon, meaning drum, and pleura, meaning side or rib (pleuron), nouns in apposition, in reference to the pseudotympanum.
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.
