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). A very troglomorphic species of Procambarus (Crustacea: Decapoda: Cambaridae), Procambarus adani Álvarez, Torres and Villalobos 2021, is also found in this cave suggesting that it has been isolated from surface to cave geneflow for a long time.
Systematics
A member of the Rhamdia laticauda species group (Weber 1996). Probably reproductively isolated from other populations of Rhamdia.
Arroyave and De La Cruz-Fernandez (2021) studied all four Mexican troglobitic Rhamdia (R. reddelli, R. zongolicensis, R. macuspanensis and R. laluchensis) with both genetics and morphology. They discovered that all four species are probably populations of the epigean Rhamdia laticauda but they refrained from making nomenclatural decisions, and thus placing all four as troglobitic populations of R. laticauda, until further data become available. The four species thus retain their current names for the timebeing (August 2021).
