All Fishes Data Sheet
Scientific Name	**Tympanopleura brevis** (Steindachner, 1881)
Common Name	Slopehead Catfish
Type Locality	Amazon River at Coary and Hyavary, Brazil.
Synonym(s)	Ageneiosus brevis, Tympanopleura alta
Etymology	Transliterated from the Greek tympanon, meaning drum, and pleura, meaning side or rib (pleuron), nouns in apposition, in reference to the pseudotympanum. The specific epithet is the Latin brevis, meaning short, perhaps in reference to the shorter head of this species in contrast to Ageneiosus inermis which was also described in the same paper. However, T. brevis is also a short bodied fish (i.e. TL), especially in relation to A. inermis; perhaps the name was used in that regard. Either way it is ambiguous.
