They are also distinguished from all their congeners by a strongly depressed head and deeply forked caudal fin with very long, lanceolate lobes, strongly asymmetric, upper lobe longest (vs. moderately depressed head and caudal fins with triangular lobes that are subequal, with upper lobe slightly longer).

Orbit not free, eyes dorsal, not visible from ventral view. Lips with large, fleshy rictal lobes, upper lip overhangs mouth, inner margin slightly plicate. Maxillary barbels reaching to midway along pectoral fin, nasal barbels reaching to two-thirds of distance to rear of head, outer mandibular barbels reaching to beyond pectoral-fin base, inner mandibular barbels reaching to posterior edge of branchiostegal membrane. Body terete, with little lateral compression; body in shape of elongate cone, widest just behind pectoral fins. Dorsal profile rising evenly but not steeply from tip of snout to origin of dorsal fin, then gently sloping posteroventrally from that point to end of caudal peduncle. Ventral profile horizontal to origin of anal fin, then sloping posterodorsally to end of caudal peduncle. Dorsal origin nearer tip of snout than end of caudal peduncle. Dorsal spine stout, without serrations on posterior edge. Depressed dorsal fin not reaching adipose fin. Pectoral spine stout, with minute denticulations along nearly of all anterior edge and with 11-14 large serrae on posterior edge (Fig. 3a). Anal origin slightly posterior tovertical through adipose fin origin. Caudal fin forked; upper and lower lobes lanceolate, upper lobe about twice as long as lower, with upper simple principal ray very elongate.</paragraph>

<paragraph id="CB750010F23B9EFD4B51B04BD9F8F107" pageNumber="5">Colouration in alcohol. Dorsal and lateral surfaces of head, body, and middle rays of both lobes of caudal fin medium purplish brown; ventral surfaces of head and body cream but underside of head with scattered melanophores. Area around openings of sensory canals on dorsal surface of head of most specimens pale. Distinct, cream midlateral stripe running along lateral line; midlateral stripe begins at edge of opercle as series of isolated, aligned white spots, spot interspaces decrease rapidly posterioriorly, interspaces coalesce shortly behind dorsal-fin origin to become thin, solid white line, white line ends before caudal fin rays in most specimens; white lateral stripe crossed by vertical rows of small white spots in many specimens, each spot pale area surrounding secondary sense organ or papilla. Dorsal fin with faint, transverse, purplish brown brand across middle one-third; interradial membranes hyaline. Pectoral fin cream coloured, but with leading edge darkly pigmented. Pelvic fin cream coloured. Anal fin cream coloured in most specimens, but in one male specimen anal fin with pigmentation pattern as that of dorsal fin. Adipose fin medium purplish brown, with distal margins cream coloured. Dorsal and ventral edges of caudal fin with broad, cream-coloured band, dorsal band of caudal starting at beginning of procurrent rays, ventral band continuous with cream coloured ventor; middle caudal fin rays cream coloured from base to tips, cream coloured area around base of middle caudal fin rays spot-like, converging with midlateral stripe in some males.</paragraph>

The epithet, meaning narrow line, is proposed in reference to the thin white line along the lateral line of the new species and is to be treated as a noun in apposition.</paragraph>
