Descrição breve
Morfologia | Morfometria
Espinhos dorsais (total): 7; Raios dorsais moles (total): 7; Espinhos anais 1; Raios anais moles: 7; Vértebras: 27. This species is distinguished by the following characters: D VI + I,7; A I,7; all segmented dorsal- and anal-fin rays are unbranched; pectoral-fin rays 15, all rays unbranched except the middle 2-4; posterior longitudinal scales 8-12, mainly restricted to caudal peduncle; no scales on anterior body; body depth at pelvic-fin origin 15.1-15.7% SL; depth at anal-fin origin 12.9-13.2% SL; with cephalic sensory-canal pores; live colour of female mainly translucent with faint markings, including 5, progressively shorter, orange-brown, dash-like marks overlying vertebral column, about 10-12 narrow orange bars on the back between level of pectoral-fin base and caudal-fin base, and 5-6 widely-spaced, brown-to-orange spots on lower side between middle of abdomen and caudal-fin base; male colour unknown (Ref. 116128).
Inhabits area of extensive gradual slopes of clean white sand (in 30-35 m depth). Collected from sites located in channel passes from the outer reef to extensive inner lagoons, and were hence subject to frequent strong currents and high rates of water exchange (Ref. 116128).
