Description: A new species of Pimelodella is described from western Andean tributaries of the Orinoco River basin. The new species differs from all congeners by a unique set of characters that includes long maxillary barbel, surpassing the dorsal lobe of the caudal fin; relatively short adipose fin (32.8-36.4 of SL); 40-42 total vertebrae; posterior margin of pectoral-fin spine with 12-18 retrorse dentations along basal two thirds; laterosensory canal foramina of dentary and preopercle large and externally conspicuous. Colouration: A brown faint and narrow midlateral stripe extending from the pseudotympanum, fading posteriorly along the caudal peduncle, and ending as a spot at the caudal-fin base; and dorsal-fin base darkly pigmented, from spinelet to posteriormost interradial membrane (Cortés-Hernández, M.A., et al 2020). This genus has been in confusion for a good number of years now especially with another close member of the Pimelodidae family, Pimelodus. These notes are the following distinguishing characteristics from the two genus. Pimelodella: Adipose fin long, low with a curved margin. The humeral process is long and spiky. Body usually plain with a dark lateral stripe; rather depressed body. Pimelodus: Adipose fin short, high, with a straight or sloping margin. Humeral process broad, triangular. Body variously patterned, usually quite deep, like Synodontis. Aquarium Care: Treat as you would do with any member of the Pimelodus in that they will be predatory on small fishes in the aquarium and it is also better to keep them in small groups rather than singularly, as this will dilute the aggression. Diet: Will eat any aquarium prepared foods such as tablets, pellets, frozen and live foods. Not fussy eaters. Etymology: The specific name longibarbata: longus, long; barbata, bearded, referring to the long maxillary barbel.
