Eurycheilichthys pantherinus is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armoured catfishes, and the subfamily Hypoptopomatinae, the cascudinhos.[2] This catfish occurs in the upper and middle Uruguay River basin in Brazil and Argentina.[3][4] It inhabits shady, fast-flowing, shallow water, ranging from approximately 200–500 m (660–1,640 ft) in elevation. The substratum is predominantly stones, with little or no macrophytes.[5] This species grows to a standard length of 4.2 centimetres (1.7 in).[6] This species was forst formally described as Eurycheilus pantherinus in 1992 by Roberto Esser dos Reis and Scott A. Schaefer with its type locality given as a creek which is a tributary of the Rio Dos Touros, at approximately 28°42'S, 50°10'W in Rio Grande do Sul.[2] When Reis and Schaefer described this species they placed it in the new monospecific genus Eurycheilus. However, Eurycheilus was preoccupied by a fossil genus of cephalopods, and therefore was replaced by Eurycheilichthys in 1993.[7] E. pamtherinus is the type species of Eurycheilichthys by monotypy.[8]
