Relevant Information:	Dorsal spines (total): 0; Dorsal soft rays (total): 11; Anal spines: 0; Anal soft rays: 9 - 11; Vertebrae: 37. Flexible, unbranched first ray and ten branched rays on its dorsal fin; dorsal fin situated relatively far posteriorly; pterygiophore of anterior dorsal fin ray articulating with neural spine of tenth vertebra; blade like neural spines of vertebrae five through nine extend dorsally, diverging at their dorsal ends to form a double row of ossifications just ventral to skin between supraoccipital and dorsal fin origin; a slender supraneural at posterior end of this v-shaped predorsal trough has attached muscles extending anteriorly between bifid neural spines to supraoccipital; maxillary barbel very long , reaching posteriorly beyond anal fin base. Distal portions of dorsal, adipose and anal fins, and most part of caudal fin almost unpigmented. Remarks: There are currently nine species in this genus which are poorly known and documented. Type species is Cetopsorhamdia nasus Eigenmann & Fisher, 1916. The genus Cetopsorhamdia is documented as having the frontal fontanel small and far removed from the long parietal fontanal. The first dorsal and pectoral rays are not spinous. Bottom lobe of the caudal fin is longer and the adipose fin is three times as long as high, and its base is longer than that of the anal fin. Small to midsized genus (3-12cm). The larger species are most likely predatory of smaller fish in the aquarium as per their close relatives of the Pimelodidae family. Remarks: Evers & Seidel (2005) captured this species as a bycatch when collecting Oxyropis sp. in the central and lower portions of the Rio Tapajos in Brazil.
