Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 5; Anal soft rays: 10; Vertebrae: 34. Diagnosed from congeners by having the following unique characters: color of dorsal surface of body, back and upper sides dark-brown sometimes with depigmented area around adipose fin; cranial fontanel with two narrow openings, anterior one between mesethmoid and frontal and posterior one limited to frontal; and fontanel apertures are separated from each other through an orbitosphenoid suture beneath frontal. Can be also separated from its congeners by possessing the following combination of characteristics: nasal ossified as tube, with narrow lateral flange not sutured to mesethmoid; pectoral fin I,4; caudal-fin lobes are the same length in both adult females and males; and smaller adult size, less than 5.0 cm SL (Ref. 79512).
The type locality is characterized by fast flowing water over huge boulders. Found in large pool and backwater area with a substrate of sand, gravel and rubble over bedrock (Ref. 79512).
