<paragraph id="17314E72A18E6EF72C9CDB53B269DFC4" pageNumber="5">A robust, deep-bodied species (BD 35.4-42.2% SL, 40.0-42.2% in specimens over 50 mm SL). The four largest specimens are males (91.2, 79.2, 53.7, 49.5 mm SL) with minimal development of the testes; the remainder are immatures of indeterminate sex. Currently we have limited information on sexual dichromatism in the species. First ray of pelvic fin is the longest in the fin and is produced in large males reaching to, or overlapping the anal fin spines. Caudal fin is rounded.</paragraph>

<paragraph id="35351CF9167530B8910F354B03C4B28C" pageNumber="5">Osteology and dentition. Infraorbital series (Fig. 2a) first infraorbital (commonly termed the lachrymal) is plate-like and followed by four tubular elements. There is a small gap between the fourth and fifth infraorbitals. Infraorbital 1 has four openings of the laterosensory system. Twenty five vertebrae, of which 13 are precaudal and 12 caudal. Premaxilla and dentary with 1-3 rows of small, acutely pointed, unicuspid teeth. Outer row teeth are slightly larger than those of inner rows. Lower pharyngeal bone is narrowly triangular, with numerous, slender, shouldered unicuspid teeth on lateral parts of the bone and larger asymmetric bicuspid teeth in the central field.</paragraph>

<paragraph id="12F36D2DE605E4127367191F205F966F" pageNumber="5">Gill rakers on first gill arch. Lower limb with 9-12 tuberculate gill rakers, 5-6 elongate gill rakers on the epibranchial. No microbranchiospines are present. A well-developed hanging pad is present on roof of the pharynx.</paragraph>

<paragraph id="26D606971821C535B7758612521FAFF6" pageNumber="6">Squamation. Cycloid, 2-3 rows of scales on the cheek, 3-4 horizontal rows on the opercle. Naked dark spot on the outer edge of opercle. Chest scales are smaller than scales on flanks.</paragraph>

<paragraph id="B4D64D46F8627CCDE9CD2E84F18BB134" pageNumber="6">Upper lateral line separated from dorsal-fin base at its highest point (8th pored scale) by 2 scales, at last pored scale by ½-1 scales. No overlap between the end of upper lateral line and lower lateral line. Caudal fin scaled basally for about one third of its length; other fins are unscaled.</paragraph>

<paragraph id="5713A18C6021CD03E17EAA77D5D98472" pageNumber="6">Coloration. Living specimens: Base body coloration is pale bronze brown with a dark spot on outer edge of opercle, no other body markings are evident. Dorsal, anal and caudal fin membranes with numerous rows of dark maculae (MLJS, pers. field obs.).</paragraph>

<paragraph id="CB873569EE900972FF6AA33F2A468F92" lastPageNumber="7" pageNumber="6">Preserved specimens (Fig. 1): Coloration of the head and body is pale to dark brown and darker dorsally than ventrally. A midlateral stripe is variously developed, passing from the eye through the opercular spot onto the anterior third of the body. The midlateral stripe is interrupted from mid-body to the caudal peduncle, and does not extend over the caudal fin. Four-5 vertical bars are variously developed from the dorsum to somewhat below the midlateral stripe. The unpaired fins are dusky grey to brownish. The soft-dorsal, soft-anal and caudal fin membranes have numerous rows of dark maculae.</paragraph>
