''Nosferatu'' is a genus of cichlid fishes endemic to the Rio Panuco Basin and the tributaries of the adjacent Tamiahua Lagoon (to the South) and San Andrés Lagoon (to the North)〔 in the states of Veracruz, Hidalgo, San Luis Potosí, Tamaulipas and Querétaro, Mexico. The genus is characterized by a prolongation in the size of the symphysial pair of teeth relative to that of the other teeth in the outer row of the upper jaw (nosferatuform teeth); breeding pigmentation that consists of darkening of ventral area extending over nostrils, opercular series, and pectoral fins; depressed dorsal fin rarely expands beyond anterior third of caudal fin; and an elongated, elastic, smooth caecum adhered to a saccular stomach. All species in ''Nosferatu'' had previously belonged to its sister genus ''Herichthys''.〔〔Kullander, S.O. (2003): Check List of the Freshwater Fishes of South and Central America.
