Family:  Gobiidae (Gobies), subfamily: Gobiinae
Max. size:  3 cm SL (male/unsexed)
Environment:  reef-associated; depth range - 150 m
Distribution:  Western Pacific: definitely known from Indonesia. Occurrence in Australia, the Philippines, Palau, and Japan (and other countries not mentioned) need further confirmation through genetic data..
Diagnosis:  Dorsal spines (total): 6-7; Dorsal soft rays (total): 9-9; Anal spines: 1-1; Anal soft rays: 8-8. This species is distinguished from its congeners by the following set of characters: cephalic sensory-pore system pattern IV of Lachner & Karnella (1983); i.e. the PITO and IT pores are lacking and the AITO pore is enlarged); dorsal/anal-fin formula 9/8, unbranched pectoral-fin rays; genital papilla of male non-fimbriate; usually pectoral-fin base with a few chromatophores restricted to an area across from the top few fin rays, but more pigmentation on the rest of the base can be present; when preserved ventral half of body with a slightly dusky stripe, wider than eye diameter at middle of anal fin, with a dark semi-circular spot at the caudal-fin base. When alive: ventral half of body red with a narrow white line above it running the length of the body; eye with a narrow white line running across it above the pupil, a short white line behind the eye, and a small white spot under the eye (Ref. 95677).
Biology:  Lives among branching and encrusting corals (Ref. 9210) in lagoon reefs at depths of 10 or more (Ref. 37816, 48637). Forms groups among branches of Acropora coral (Ref 90102).
