Short description Morphology | Morphometrics

Dorsal spines (total): 46 - 48; Anal spines: 2; Anal soft rays: 30; Vertebrae: 52 - 54. This species is distinguished by having the following characters: DXLVI-XLVIII; A II,28-30; membrane extremely incised, rays elongate; 11 pectoral-fin rays, including 3 ventralmost rays free from others and the longest ray 36.5-40.2% SL; pelvic fin rays elongate, membrane well-incised, and rays unbranched; 2 mandibular pores; 1 or 2 large black blotches on pectoral fin; black ocellus on caudal fin (Ref. 84251).

The specimens have well-developed ovaries containing ca. 1.5 mm diameter eggs, suggesting the spawning of the species occurs in autumn (Ref. 84251).
