Can be diagnosed from all of congeners in the Bomberai Peninsula and Birdâs Neck region by the combination of the following characters: dorsal fin with IV to VI-I,14 to 15 rays; anal fin with I,22-25 rays; 34-36 lateral scales; 10-11 transverse scales; 15-17 predorsal scales; 14-18 cheek scales; 15-16 gillrakers; snout length 8.0-9.1% of SL; interorbital width 8.4-9.0% of SL; body depth 28.7-32.8 and width 11.4- 13.5% SL; caudal peduncle length 14.0-16.1 and depth 10.0-11.1% SL; predorsal length 47.3-49.5% of SL; prepelvic length 38.3-40.4% of SL; preanal length 49.6-52.8% of SL; spine length of the first dorsal fin 10.2-12.1% of SL; spine length of the anal fin 9.1-10.4% of SL; dorsal-fin base length 36.8-40.5% of SL; second dorsal-fin base length, 24.3-27.5% of SL; a prominent white margin stripe with a reddish extremity respectively on the second dorsal fin and on the anal fin (Ref. 91054).
Morphology
provided by Fishbase
Dorsal spines (total): 4 - 6; Dorsal soft rays (total): 14 - 15; Analspines: 1; Analsoft rays: 22 - 25
Biology
provided by Fishbase
The type locality, Wermura Creek, emerges from a small cave then flows on about 200 m before disappearing in a subterranean outlet and reappears after 1 km in the mangrove from a large cave and flows to the Arguni Bay. It consists of a crystalline stream, narrow (to about 1 m wide), relatively shallow (up to about 1 m) and flowing in primary forest (Ref. 91054).
