Chaves de identificação | Morfologia | Morfometria
This species is distinguished from its congeners in the Birds Head region by the following characters: D IV-VI+I, 13-14; A I, 23-26; 37-40 lateral scales; 10 transverse scales; 19-21 anterior scales; 17-18 cheek scales; 19 gillrakers on first arch; short head length, 24.1-25.2% of SL; thin interorbital width, 7.8-8.2% of SL; long predorsal length, 50.2-51.8% of SL; long pelvic fin length, 19.6-20.4% of SL; long spine length on first dorsal fin, 13.1-15.3% of SL; moderately elongate second dorsal fin spine, 12.4-15.7% of SL; elongate anal fin spine, 10.1-11.3% of SL; short dorsal fin base, 33.4-36.5% of SL; short 2nd dorsal fin base, 20.2-22.6% of SL; dorsal fin base protruding vertically behind anal origin, between 1st and 3rd anal soft ray; absence of stripes on dorsal fins margin (Ref. 103156).
Collected from the type locality, a river which flows through secondary rainforest over gravel and sandy bottom. The habitat has turbid water and no aquatic vegetation. Maximum length based on type specimen, to be replaced with a better reference (Ref. 103156).
