Morphology | Morphometrics
(total): 4 - 5;
soft rays: 20 - 24. Differs from other species of the genus Melanotaenia in the Bomberai Peninsula and Bird’s Neck region by the combination of the following characters: dorsal rays IV to V-I,12 to 16; anal rays I,20-24; lateral scales 34-37; transverse scales 10-11; predorsal scales 16-18; cheek scales 14-20; gillrakers 17-18; a short snout length, 8.3-9.1% of SL; a thin interorbital width, 8.3-9.0% of SL; a small eye diameter, 6.6-7.2% of SL; a thin body width, 11.0-13.0% of SL; a short and thin caudal peduncle (its length, 14.1-16.1 and depth, 10.0-10.8% of SL); a moderately long predorsal length, 36.8-39.7% of SL; a long preanal length, 49.7-52.9% of SL (Ref. 91054).
The type locality, Jasu Creek in Egerwara village, is a stream characterized by less than 5 m width. Habitats in the vicinity of the type locality include shallow and slow flowing water over sandy substrate in secondary forest and cocoa plantations (Ref. 91054).
