Genus Cetopsis Spix & Agassiz

Cetopsis Spix & Agassiz, 1829: 8 , 11 [type-species: Silurus coecutiens Lichtenstein, 1819 , by subsequent designation by Bleeker, 1862b].

Hemicetopsis Bleeker, 1862a: 403 [type-species: Cetopsis candiru Spix & Agassiz, 1829 , by original designation].

Pseudocetopsis Bleeker, 1862a: 403 [type species: Cetopsis gobioides Kner, 1857 , by original designation].

Bathycetopsis Lundberg & Rapp Py-Daniel, 1994: 382 [type species: Bathycetopsis oliveirai Lundberg & Rapp Py- Daniel,1994, by original designation].

Diagnosis. The combination of the absence of a spinelet associated with the dorsal fin, the absence of spines on the dorsal and pectoral fins, and the possession of a single row of teeth on the vomer distinguishes Cetopsis from the other genera in the Cetopsinae .

Remarks. The concept of Cetopsis utilized in this paper is considerably more encompassing than was the concept of the genus that was utilized in recent publications under which Cetopsis included only a single species, C. coecutiens (see “Systematic Overview” above).
