Types

Holotype: ZMH 8874, 124.7mm SL, 150.8mm TL. Paratypes: ZMH 8875, 138mm SL, 168mm TL. ZMH 8876 (8 specimens, 78.3 - 135.9mm SL).

Distribution

Known only from the type locality: Grutas de Agua Blanca, Balneario de Agua Blanca, on the road from Villahermosa to Chetumal, 20 km SE of the village of Macuspana, Tabasco, México (17o37’15.5”N, 92o28’22.6”W).

Habitat

The cave stream runs over bare limestone but there are areas of sand and gravel. No food was seen when the type series was collected and it is likely that it arrived with flood events. The fishes were well fed with deposits of adipose tissue. Bat guano may also supply some supplies (Weber and Wilkens 1998). The stygobiootic crab Rodriguezia adani Alvarez and Villalobos 2018 is also found at this site (see Zoobank entry), as are the pseudothelphusid crab Odontothelphusa palenquensis, an undescribed species of Macrobrachium prawn, a Procambarus crayfish and asellid isopods (Alvarez and Villalobos 2018). These animals are likely to be food for R. macuspanensis.

Systematics

A member of the Rhamdia laticauda species group (Weber 1996).
