Short description Morfología | Morfometría

Radios blandos dorsales (total): 84-91; Radios blandos anales: 63 - 69; Vértebra: 50 - 52. This species is distinguished from its congeners by the following combination of characters: Vertebrae 12-13+37-39=50-52, dorsal fin rays 84-91, anal fin rays 63-69, pectoral fin rays 17-18, caudal fin rays 10; head profile above eye strongly depressed, scales on occiput, eyes present (0.9-1.0 % SL); palatine teeth absent; color uniformly light brown, long gill-rakers 3, pale (Ref. 57878).

Found in an anchialine cave which is connected to the sea via a submerged passage which opens into a tidal saltwater creek. The upper about 14 m in the cave consists of freshwater (22 °C), separated from a lower, slightly warmer (23-25 °C), salty layer by a distinct halocline. The holotype was taken in a depth of 12 m, which must then most likely to be freshwater; some where collected from one or two inland sink holes (Ref. 57878).
