Rhamdia is a genus of three-barbeled catfishes found in Mexico, Central and South America. These catfishes are nocturnal, opportunistic carnivores, found in a wide range of freshwater habitats. ^[1] This genus includes a number of troglobitic members, encompassing a number of taxa, including R. enfurnada, R. guasarensis, R. laluchensis, R. laticauda, R. macuspanensis, R. quelen, R. reddelli and R. zongolicensis. ^{[1] [2]} In a few of these only some of their populations are troglobitic. ^{[1] [2]}
