Summary:
A pale olive to dusky or brown shrimpgoby with three broad darker irregular bars on the body extending onto the fin bases, a bar on the gill cover extending onto the nape, oblique blue spots or streaks on the head, small blue spots on the pectoral-fin base, bright blue spots covering the pelvic fin, rows of bright blue stripes on the anal fin, and bright blue membranes on the lower half of the caudal fin. 
This species is very similar to (and may be conspecific with) Cryptocentrus fasciatus (Hoese 2015).

More Info


Distribution

Endemic to Queensland, from the Low Isles to Fraser Island. Inhabits inshore sandy/silty areas.

Features

Holotype: Dorsal fin VI + I, 10; Anal fin I, 9; Pectoral fin 18; Caudal fin 14 branched rays; Scale rows (to hypural) 71; Transverse scales 29.
Head (29 mm.) 3.1 in SL, depth (19) 4.8 in SL, breadth of body (12) 7.6 in SL; eye diameter less than snout length. Ocular tentacle absent; maxilla reaching to below eye; teeth in villiform bands on jaws and palate, a few front teeth in upper jaw very slightly enlarged; nostrils small, posterior rounded, near eye; anterior nostril valved, nearer upper lip. Head-pores inconspicuous; head naked except on nape; a few vertical rows of minute papillae arising above upper operculum, one row crossing nape to join the opposite row, other rows in fold on each side of chin; a transverse v-shaped fossa across nape behind eyes. 
Scales small, cycloid. Third and fourth dorsal spines elongate; pelvic fins united, nearly reaching anus, 10th ray longest; caudal fin rounded, nearly as long as head, with fourteen branched rays, the lowermost short. (From Whitley 1956)

Colour

A pale olive to pale yellowish-brown or brown shrimpgoby with three broad darker irregular bars on the body (bars sometimes divided on the back and extending onto the fin bases), a bar on the gill cover extending onto the nape, and a dark patch on the rear of the caudal peduncle. Head covered in oblique blue spots or streaks, pectoral fin base and basal part of fin with small blue spots, pelvic fin pale dusky to dark brown and covered in bright blue spots, anal fin dusky to dark brown with about five rows of blue stripes, and lower part of caudal fin with bright bluish membranes. 

Similar Species

Apart from these images, the Bluelined Shrimpgoby is known only from the holotype from Palm Island, Queensland. It is very similar to and may be identical with Cryptocentrus fasciatus (Hoese 2015)

Etymology

The specific name bulbiceps presumably refers to the bulbous cheeks of this species which were described by Whitley as "bulging".
