Description: Cetopsis baudoensis can be distinguished from all of its congeners by the combination of the presence of an eye, the conical teeth on the vomer and dentary, the rounded posterior nares which is distinctly separated from the contralateral nares by a distance greater than the width of the posterior nares, the wide mouth with its width equal to one-half of HL, the absence of a dark humeral spot, the absence of a posteriorly-rounded, variably-developed, bilobed patch of dark pigmentation at the base of the caudal fin, the absence of a band of dark pigmentation along the distal portions of the anal fin, the possession of small dark spots on the lateral and dorsal surfaces of the body, the absence of eye-size or larger spots on the body, the possession of 9, rarely 10, pectoral-fin rays, 18 to 20 preanal vertebrae, 14 to 16 precaudal vertebrae, 33 to 35 caudal vertebrae, 47 to 49 caudal vertebrae, 20 to 22 branched anal-fin rays, and 23 to 27 total anal-fin rays. Habitat: It lives on highly turbid, white water rivers over clay bottoms with logs in the main riverbanks and clay and leaves in the lower parts of creeks. Specimens were collected at depths of 2m or less and at elevation of less than 50m asl (Vari et al. 2005). Remarks: Cetopsis baudoensis has a very restricted range; its extent of occurrence is less than 270 km². The single location where it occurs is affected by deforestation, but it is not certain whether this impact is leading to a continuing decline in habitat quality. Hence, the species is listed as Near Threatened, as it almost qualifies for listing as Endangered under criterion B1ab(iii) (IUCN 2016).
