Diagnosis

Can be diagnosed from all its congeners from Bomberai Peninsula and Bird’s Neck region by the combination of the following characters: dorsal fin with IV to V-I,12 -15 rays; anal fin with I,21-23 rays ; 36-39 lateral scales; 10-11 transverse scales; 18-20 predorsal scales; 13-16 cheek scales; 17-18 gillrakers; head length 23.7-25.2% of standard length; snout length 7.6-8.7% of SL; interorbital width 7.9-8.8% of SL; eye diameter, 8.0-9.0% of SL; body width 10.0-11.2% of SL; predorsal length 50.6-54.5% of SL; prepelvic length 36.3-39.2% of SL; preanal length 47.0-49.1% of SL; caudal peduncle length 16.3-19.0 and depth 8.6-10.0% of SL; pectoral fin length 15.2-17.4% of SL and pelvic fin 11.0-13.7% of SL; anal fin height 6.8-9.9% of SL; spine length on the anal fin 7.1-8.5% of SL; dorsal-fin base length 30.8-35.7% of SL and second dorsal-fin base length 20.4-23.5% of SL (Ref. 91054).
