Diagnosis

Diagnosis: Predorsal scales and a bony interorbital about pupil diameter in width. Second dorsal spine elongated. Fifth pelvic fin ray branched dichotomously once and 55-80% of the fourth. Scales on cheek absent; one or two cycloid scales on the upper opercle; usually two rows of scales anterior to the pelvic fin base. Snout and lower half of the caudal peduncle with a slight sprinkling of melanophores. A broad, rounded, median ridge present on the snout and anterior interorbital region. Unique to the genus, a large, bilateral, open nasal pit, instead of the usual nasal sac with anterior and posterior openings (Ref. 55345); characterized further by semi-translucent pinkish, abdomen and most of head reddish pink, merging with tapered pink stripe to middle caudal fin base; midline of snout with blue-white spot; internal white stripe above vertebral column; longitudinal scale series 23-25; predorsal scales 6-8 (Ref. 90102).
