背棘 (总数) : 0; 背的软条 (总数) : 15 - 16; 臀棘: 0; 臀鳍软条: 15 - 16. A slender and elongate species (Ref. 56139).

Females have a brown body, dorsally darker than ventrally; red dot at the end of scales, fusing to a reticulated pattern on caudal peduncle; unpaired and pelvic fins transparent with interradial red flames, anal and pelvic fins with traces of a small blueish marginal band, pectoral fins transparent with a small whitish marginal band (Ref. 56139).
