Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 10. This species is distinguished by the following characters: absence of pore D; often 15 (15-16) pectoral rays; first dorsal fin spines flex posteriorly only slightly at tips in males, the 6th spine is the longest; males with a large spot medially on first dorsal fin and have blackish caudal peduncle (vs. whitish in females) both jawa with conical teeth in males and only on lower jaw in females (Ref. 39342).
Found in swift, clear mountain stream, above several waterfalls, with rocky and boulder-strewn bottom, together with Stiphodon birdsong, several species of Sicyopterus and S. mystax (Ref. 39342).
