Family:  Engraulidae (Anchovies), subfamily: Coiliinae
Max. size:  12 cm SL (male/unsexed)
Environment:  pelagic-neritic; brackish; marine; depth range - 13 m
Distribution:  Western Central Pacific: Gulf of Papua (off Port Romily; in mouths of rivers flowing into the Gulf; Arafura Sea, but no indication if Australian or Irian Jaya coast).
Diagnosis:  Dorsal spines (total): 0-0; Dorsal soft rays (total): 3-4; Anal spines: 0-0; Anal soft rays: 51-57. Belly with 5 or 6 pre-pectoral needle-like scutes, none behind, and a series of membrane-like post -pelvic scutes more or less concealed by the scales. Maxilla short, tip blunt; first supra-maxilla large, elongate, more than twice length of second. Pectoral fins wing-like; pelvic fins small; dorsal fin minute, the second unbranched fin ray elongated. A distinct dark blotch behind gill opening.
Biology:  Presumed to be estuarine, but perhaps ascends rivers or migrates into coastal waters. The minute teeth and rather numerous gillrakers suggest a diet of small planktonic animals. The species is probably uncommon as there seems to be only four preserved specimens.
IUCN Red List Status: Data deficient (DD); Date assessed: 17 July 2017 Ref. (130435)
