Fins - D1 - VII, filamentous in adult males- first spine; D2 - 11(10-12); pectoral 18(16-19); anal - 10(9-10); pelvic I,5 all branched, 4th ray longest; disk complete
Head - Maxilla extending to posterior of eye; anterior nostril very short tube; posterior nostril a raised rim or less.
Papillae - A transverse pattern with three vertical rows anterior to row b; row 5i/6i attached to the anterior of row b; no vertcial rows extending below the level of row d
Color - In life this species has two characteristic round, orange areas on each side seperated from each other by the black ") (" mentioned in the original description and by a whitish area that the black marks enclose. (B&R)
Preserved color - banded but not strikingly so. There are eight equally spaced dark bands between the origin of the second dorsal fin and the caudal base. The bands are nearly vertical and are narrower than the interspaces. A dark basicaudal bar is present. Anterior to the second dorsal fin the bands apparently are restricted to the dorsum and upper sides. One crosses the dorsum between the dorsal fins, 3 are under the spinous dorsal fin and 3 are represented by saddles on the predorsum, the anteriormost an open, caudally driected 'V' behind the orbit. The preopercular margin is crossed by a dark band. A dark blotch extends posteroventrally from the hind corner of the eye. A dark bar extends ventrally from the eye and crosses the lips. A dark mid-rostral band extends from the snout tip across both lips in the holotype. A dark spot is at each anterior nostril but the nasal tube itself is pale with scattered melanophores. The head markings are similar in general to those of G. saucra but not so bold. The most characteristic feature of pigmentation lies in the peritoneum which is generally dusky with 3 dark bars, all visible externally. Two are close together on the mid-side with a pale area between. The third is internal to the axil of the pectoral fin. (R&B 64)
