Dorsal spines (total): 0; Dorsal soft rays (total): 11; Anal spines: 0; Anal soft rays: 8; Vertebrae: 43. Diagnosis: elongate, small species, body depth 6.4-8.0 times in SL; body width 8.2-10.0 times in SL; head rather short, 4.9-5.5 times in SL, about twice as long as broad . Head smooth, round in front, flat below . Eye laterodorsal , about 4.1-5 times in HL, 0.9-1.3 times in interorbital distance and 1.6-2.1 times in snout length , its horizontal diameter slightly less than interorbital distance; snout length equal to postorbital distance; interorbital distance about equal to mouth width; jaws without teeth, but with horny edges to jaws . Mouth straight, tadpole-like; gill openings form a slit above pectoral fins . Dorsal fin origin very slightly anterior to pelvic fin origin, slightly posterior to midpoint of SL , nearer to origin of caudal fin than to snout .
