Country

México

Types

Holotype: ZMH 8249 92mm SL. Paratypes: ZMH 8250, 3 specimens 65-85mm SL.

Distribution

Known only from the type locality: Cueva del Ostoc, Sierra de Zongolica, Veracruz, México (18oN, 97oW). This cave is also known as Cueva de El Túnel and under this name was described by Robertson (1983) and Mosier (1984) both of whom mentioned the fishes, the former also providing a photograph.

Habitat

There is little published information. Wilkens (1993a) reports that there was no other animal life in the pools in the cave and that the type specimens were undernourished. This may suggest that the food supply is episodic, perhaps related to flood events. Robertson (1983) provides a survey.

Systematics

Silfvergrip (1986) does not accept that this species is diagnosable from Rhamdia laticauda and places it within that species.
