Pterolebias hoignei n. sp. is similar to but differs from P. zonatus Myers in color pattern, male fin development and several morphometric and meristic characters. P. zonatus occurs in open sunlit habitats and is widespread in the Orinoco basin of Venezuela and Colombia. P. hoignei is known only from shaded pools in a small area in Estado Cojedes, Orinoco basin, Venezuela. The two species occur within a few km of each other but have not been taken together. There is no evidence of hybridization or gene exchange.
