species in having 5–6 developed rakers on anterior gill arch and no spines on frontal plate and ethmoid. Also the following combination of characters is diagnostic: Skin thin and transparent; numerous neuromasts below translucent head skin arranged in five distinct clusters; scales absent; three developed rakers on anterior gill arch 3–4 times length of gill filaments; palatines with one row of teeth; antero-ventrally directed spine on lower angle of preoperculum; prolonged pectoral peduncle; precaudal vertebrae 16 and total vertebrae 54; fin rays in dorsal 91, anal 64 and pectoral 14.

B shows a conspicuous thickening of the frontal at the location where spines would be expected, indicating that larger specimens might in fact have small frontal spines. Also a broad hump is indicated on the snout at the position where a (cartilaginous) spine might be expected. Anterior nostril placed close to upper lip; posterior nostril moderately large with anterior flap, placed close to eye. Head pores: 2 supraorbital pores near tip of snout, 1 anterior infraorbital pore below and in front of eye, 1 anterior mandibular pore at tip of jaw. Head skin thin, tight. Total of 17–18 diamond-shaped, light-colored neuromasts visible below transparent skin arranged in five clusters: 4 infraorbital along upper lip and curving around eye, 2 pairs between eyes, one of them slightly in front of eyes, 6 supraorbital along line above opercle and behind eyes, 2–3 mandibular along jaw, 3 on the lower preopercle. Head with dusky background pigmentation chiefly around neuromasts. Upper jaw ends well behind eye; posterior end of maxilla vertically expanded. Opercular spine pointed but flat, subdermal, not reaching hind margin of opercle. Small, subdermal anterior-ventrally pointed spine at lower angle of preoperculum.
