Scleromystax is a genus of fish in the family Callichthyidae endemic to small tributaries from several coastal river basins draining the southern and southeastern regions in Brazil.[1] Most of the species of Scleromystax are highly sexually dimorphic; males have developed odontodes inserted in fleshy papillae on the preopercular-opercular region and the dorsal and pectoral fins are 23 times as long as those of females.[1] S. salmacis is an exception, as its sexually dimorphic features are subtle and non-remarkable.
