Types

Holotype: ZMH 9373, 119.5mm SL. Paratypes: ZMH 9374, 4 specimens, 60.2-77.0mm SL; BMNH 1982.10.27:1-5, 5 specimens, 65.3-108.7mm SL. 

Distribution

Known only from the type locality: Sistema de La Lucha, Municipio Ocozocoautla, Chiapas, Mexico (entrance c. 5 km southwest of the village of Aguablanca on the eastern shore of the Malpaso Reservoir) (17o03’40”N, 93o53’23”W).

Habitat

The Sistema de La Lucha normally carries a small resurgent stream but floods dramatically at times. The stream rises from a flooded passage and both the outlet and a lake further downstream contain many individuals of R. laluchensis. Water temperature was 18oC in April. There is a rich fauna within the cave. (Details from Weber, Allegrucci and Sbordoni 2003)

Systematics

A member of the Rhamdia laticauda species group (Weber 1996). Probably reproductively isolated from other populations of Rhamdia.

Conservation Status

TLO [NE]

Known only from the type locality and therefore VU D2.

Museum Holdings

As above only.
