Distribution

Offshore reefs of north Western Australia, Ashmore Reef in the Timor Sea, and the Great Barrier Reef to One Tree Island, Queensland, and reefs in the Coral Sea. Elsewhere, the species is widespread in the Indo-West Pacific, from the Red Sea and Western Indian Ocean to Taiwan, southern Japan and Fiji.
Shares burrows with alpheid shrimps of the genus Alpheus on sand and rubble areas adjacent to the reef.

Features

Dorsal fin VI + I, 11-12; Anal fin I, 11; Pectoral fin 18-19; Lateral scale rows 51-56.
Body elongate, compressed, head slightly compressed; jaws extending posteriorly to below middle of eye; gill opening reaching anteriorly to below posterior margin of eye.
Scales ctenoid posteriorly, cycloid anteriorly; head, breast and pectoral-fin base naked. Sensory canals and pores present on head; cheek with reduced longitudinal pattern of sensory papillae; a pair of sensory papillae just behind chin.
Pelvic fins united medially, frenum present; elongate dorsal-fin spines absent. 

Colour

About 4 irregular horizontal rows of dark brown dotted and/or dashed lines along the  body (dashed midlateral line most distinct); two parallel oblique orange dashed-lines on cheek; pectoral fin with a bright white streak.

Etymology

The specific name crocineus is from the Latincrocum (= saffron spice), in reference to the orange-yellow colour of this species as depicted in the illustration of the holotype.
