Distribution

Endemic to continental slope waters of the Coral Sea off northeastern Australia, from off Townsville to off Rockhampton, QLD.

Features

Head short 17.2-19.6% TL, narrowly parabolic in dorsoventral view; eye small, positioned dorsolaterally, length 3.4-3.9% TL, 1.73-2.03 in snout; labial furrows well-developed, extending well beyond corners of mouth, lower furrow slightly longer than the upper furrow. Vertebrae 140-149, 35-38 monospondylous, 85-93 precaudal.
First dorsal fin slightly smaller than the second dorsal fin. Pelvic fins small, slender, length 8.8-11.3% TL, rear part strongly directed posterodorsally (forming a small lobe, enveloping partly the proximo-lateral margin of clasper), inner margin strongly convex forming a partial apron and connected to clasper dorsomedially near its base, soft tissue connecting pelvic fin insertion weak, not forming a prominent apron overlying ventral surface of tail. Anal-fin base 9.9-10.9% TL, 2.4-6.0 times anal-caudal distance, much longer than second dorsal-fin base; caudal peduncle elongate, anal-caudal space 1.6-4.2% TL. 
Crest of enlarged denticles on anterior dorsal caudal-fin margin extending from above origin of ventral caudal-fin lobe almost to mid-length of dorsal caudal-fin margin; crest of enlarged denticles originating at mid-point of caudal peduncle, extending to elevated part of ventral lobe.

Colour

In preservative: pale brown dorsally, with dark saddles and bars, lighter ventrally; pre-dorsally with about 4 larger saddles; saddles present below and between dorsal fins and extending onto caudal, these are rarely larger than eye diameter; larger saddles are pale edged, separated by narrower, less distinct bars; saddles rarely extending below the lateral midline.

Etymology

The specific name striatus is from the Latin striatus meaning 'striped', in reference to the striped colour pattern of this species.
