Neofundulus is distinguished from the remaining genera of Rivulidae family by having the following synapomorphies: fourth pectoral radial not expanded ventrally, a subasal longitudinal white-yellowish stripe on the anal fin in males, transverse black bars on caudal fin of females, and black spots on pectoral fin of males (Costa 19986) Neofundulus splendidus presents very narrow yellow lines on the pectoral fins, instead of black spots present on the other Neofundulus species, thus an autapomorphy of this species.
