Morphological description (GBIF)(Mô tả hình thái (GBIF))

Description. Dorsal-fin rays XIII, 19; anal-fin rays II, 19; pectoral-fin rays 14; pelvic-fin rays I, 4; segment caudal-fin rays 6 + 5 (branched 5 + 4); vertebrae 12 + 24; no nuchal cirri; supraorbital cirri 1 (both side distally divided into four branches); nasal cirri 3 (4 in left side); lateral line tubes 28 (both side). Morphometrics are presented in Table 1. The body is elongate, slightly compressed posteriorly, and deepest at the base of the pectoral fin. The snout is slightly elevated, and the dorsal profile from the anterior margin of the eye to the snout is nearly vertical, then gently rising toward the nape before gradually descending to the caudal peduncle. The ventral profile is slightly convex from the lower jaw tip to the origin of the pelvic fin, then nearly straight and parallel to the body axis toward the anus, followed by a slight rise along the anal-fin base and becoming nearly straight again prior to the caudal peduncle. The anus is located slightly anterior to the mid-body. The head is rounded and widest at the mid-cheek region. The eye is moderately sized and positioned anterodorsally. The nuchal cirri occur in two separated clusters, divided at the mid-nape. The cephalic sensory pore system is complex. The posterior portion of the dorsal-fin rays is separated from the fin base, and the posteriormost fin membrane does not attach to the caudal peduncle. The anal-fin base extends from directly below the 13 th dorsal-fin spine to a point directly below the posterior end of the dorsal-fin base; the posteriormost anal-fin ray is split from the base. The caudal fin is arcuate. The pectoral-fin origin is located below the first dorsal-fin spine, and the ventralmost pectoral-fin base aligns below the second dorsal-fin spine; the longest ray extends anterior to the anus, and the posterior margin is rounded. The pelvic-fin origin lies anterior to the vertical line passing through the nuchal cirri, and the fin length reaches to the base of the fourth dors
