This species is distinguished from Callogobius sclateri by having a partially united pelvic fins (vs. pelvic fins completely separate even in tiny juveniles of C. sclateri), and with preopercular papillae row (Row 20) continuous with the transverse opercular row (Row 21) (vs. separate) (Ref. 93174).

Description: Elongated and compressed body; longer and projecting lower jaw; numerous raised lines radiating from eye, others cross the cheek, snout, and nuchal region, these probably function as mucus canals; teeth minute on jaws, while none on vomer and palatines; caudal peduncle 2.6 in head; the origin of spinous dorsal slightly behind to a line with axil of ventrals, the longest spine 2 in head; the base of soft dorsal about equal to its longest ray 1.75 in head; anal fin similar to soft dorsal, the base slightly less; rounded and rather long pectorals, its tips under the base of fifth dorsal ray; united ventrals into a flat disk that reaches the anal opening; rounded caudal fin and about 1.1 in head (Ref. 412).
