Body with slight convex curve from posterior part of first dorsal fin base to moderately narrow caudal peduncle; narrow but distinct postorbital notch above and behind each eye and faint furrow across nape at rear of interorbital space; rostral process with broad to deep medial notch and nearly straight to slightly curved anterior edge on each rostral lobe to triangular spine of moderate size at apical corner.

Pectoral fins reaching about fourth or fifth anal fin ray, first free pectoral fin ray reaching to between anus and base of third anal fin ray, not or just reaching tip of pelvic fin. 

Size

154 mm SL

Colour

Body above lateral midline and head reddish, lower half of sides and underside of head white; first dorsal fin pink with elongate red spot on the basal half of fin between third and sixth spines; distal portion of second dorsal reddish, white basally; anal fin white; broad red band just distal to middle of caudal fin with broad ventrally tapering pink margin and transverse red band basally; pelvic fins white; inner surface of pectoral fin dark greenish brown with large black patch covering ventral third to half of fin from base to distal margin except for fine red margin dorsally and distally and broad red margin ventrally, prominent white spots scattered over all but red areas on fin, rays on outer surface white with membranes matching inner surface on upper two thirds of fin, pink ventrally and on free rays.

An occasional bycatch species in trawl fisheries.

Remarks


Similar Species

This species has previously been mistaken for Lepidotrigla punctipectoralis in northern Australia and south east Asia.

Etymology

The specific name spiloptera is from the Greek spilotos (= spotted) and pteron (= wing) in reference to the distinctive white spots spread across the inner surface of the wing-like pectoral fin.
