Các tia vây lưng cứng (tổng cộng) : 7; Các vây lưng mềm (tổng cộng) : 10; Tia cứng vây hậu môn: 1; Tia mềm vây hậu môn: 10; Động vật có xương sống: 26. This species is distinguished by the following characters: D VI-I,10, no elongated dorsal-fin spine, the longest 1.0-1.3 in HL; A I,10; pectoral-fin rays 17-18 (usually17); lateral scale series 78-84; entirely with cycloid scales, none on cheek, opercle, predorsal, and pectoral-fin base; gill opening extending to about the level of posterior edge of preopercle; caudal fin rounded, about equal to head length or 3.2-3.6 in SL; pattern of cephalic sensory-canal pores consisting of B’, C, D, E, F, G, H’, M’, N and O’ pores; gill rakers poorly developed, 2 + 4-6. Colouration: when alive, overall whitish with midlateral row of 4 large, ovate, brown spots, 5 or 6 diagonal yellow-orange bands on first dorsal fin, a brown stripe along middle of second dorsal fin; anal fin with several yellow-orange stripes; pelvic fins bluish with yellow fin rays (Ref. 31301).
Cross section: compressed.
Collected from relatively flat sandy bottoms exposed to periodic strong tidal currents in 15-24 m depth with temperature ranging from 20 to 28 °C across the year. Most individuals observed appeared to be solitary, while about 20% of burrows encountered had a pair of shrimpgobies guarding the entrance. Observations during peak tidal currents showed that nearly all shrimpgoby burrows were completely covered by shifting sands; only during slack tides would the alpheid shrimp reopen the burrow entrances. Many other species of shrimpgoby were commonly observed within 1 or 2 m of burrows of the new species, including Amblyeleotris diagonalis, A. novaecaledoniae, A. ogasawarensis, A. rubrimarginata, A. steinitzi, A. wheeleri, Ctenogobiops mitodes, C. pomastictus, and Stonogobiops xanthorhinica (Ref. 131301).
