Supraorbital canal, posterior section of infraorbital canal and postorbital canal continuous. Supraorbital sensory canal with 3 paired pores: s1, adjacent to medial margin of anterior nostril; s3, adjacent and just posterior to medial margin of posterior nostril and s6, at transverse line through posterior half of orbit; s6 pore about equidistant from its symmetrical homologous s6 pore than orbit. Infraorbital sensory canal with 2 segments. Anterior infraorbital canal with 2 pores: i1, at transverse line through anterior nostril and i3, at transverse line just anterior to posterior nostril. Posterior infraorbital canal with two pores: i10, adjacent to ventral margin of orbit and i11, posterior to orbit. Postorbital canal with 2 pores: po1, at vertical line above posterior portion of interopercular patch of odontodes, and po2, at vertical line above posterior portion of opercular patch of odontodes. Lateral line of trunk with 2 pores just posterior to head.

). Anterior margin of mesethmoid nearly straight, mesethmoid cornu rod-shaped, tip rounded. Lacrimal oval, its largest length about one third of sesamoid supraorbital length. Sesamoid supraorbital narrow, rod-like, longer than premaxilla largest length. Premaxilla sub-rectangular in dorsal view, slightly tapering laterally. Maxilla boomerang-shaped, slender, slightly shorter than premaxilla, with minute posterior process. Autopalatine sub-rectangular in dorsal view when excluding posterolateral process, its shortest width about half autopalatine length, lateral and medial margins weakly concave. Latero-posterior process of autopalatine triangular, its length about two thirds of autopalatine length excluding anterior cartilage. Metapterygoid subtriangular, deeper than long, with distinctive posterior projection; anterior margin weakly bent, posterior margin slightly sinuous. Quadrate robust, dorsoposterior outgrowth in close proximity to hyomandibular outgrowth. Hyomandibula long, anterior outgrowth with small concavity on dorsal margin. Opercle moderately elongate, opercular odontode patch slender, its depth about half length of dorsal articular facet of hyomandibula; dorsal process of opercle short and blunt. Interopercle long, its longitudinal length about three fourths of hyomandibula longitudinal length. Preopercle compact, without ventral expansion. Parurohyal robust, lateral process relatively elongate, sharply pointed. Parurohyal head well-developed, with minute anterolateral paired process. Middle parurohyal foramen small, its largest length about one fourth of distance between anterior margin of parurohyal and anterior insertion of posterior process. Posterior parurohyal process long, slightly longer than distance between anterior margin of parurohyal and anterior insertion of posterior process. Vertebrae 39 or 40. Ribs 13. Two dorsal hypural plates, corresponding to hypurals 4 + 5 and 3, respectively; single ventral hypural plate corresponding to hypurals 1 and 2 and parhypural.

Dorsum and flank brownish-grey, lighter ventrally, with faint brown stripe along lateral mid-line of trunk, overlapped by great concentration of rounded light brown spots extending over flank and dorsum in more superficial layer of skin. Dorsum light brown with yellowish-grey with mid-dorsal row of small brown spots between nape and dorsal-fin origin. Dorsal and lateral portions of head brownish-grey with brown spots. Ventral surface of head and trunk white. Jaws and barbels brown. Fins hyaline, with faint brown spots on basal portion of unpaired and pectoral fins. Smallest specimen (27.1 mm SL) with flank pale yellow and narrow black stripe along lateral mid-line, which becomes paler and diffuse and overlapped by brown spots in larger specimens.
