<paragraph id="F206F8D85AE5D81A650173EB9D747106" pageNumber="5">Description. Morphometric data as in Table 1. Head and abdominal region moderately broad and strongly depressed. Dorsal profile rising gently from tip of snout to origin of dorsal fin, then almost horizontal or sloping very gently ventrally to end of caudal peduncle. Ventral profile horizontal to anal-fin base, then sloping very gently dorsally to end of caudal peduncle. Caudal peduncle short, moderately deep and compressed. Anus and urogenital openings located approximately midway between posteriormost extent of pelvic fin and base of first anal-fin ray element. Skin smooth. Lateral line complete and midlateral. Vertebrae 24+17=41 (2), 25+16=41 (1), 25+17=42 (1) or 26+16=42 (1) (26+16 in holotype).</paragraph>

Gill openings moderate, extending from posttemporal region to base of third or fourth pectoral-fin element. Branchiostegal rays 4 (3) or 5 (2) (4 in holotype). Head covered with thick skin.

Maxillary barbel with thin flap of skin fringing posterior margin and pointed tip; ventral surface with numerous plicae. Barbel extending just beyond base of first pectoral-fin element. Nasal barbel with small flap of thin skin fringing posterior margin and extending to middle of orbit. Inner mandibularbarbel origin close to midline, extending to midway between lower lip margin and first pectoral-fin element.
