Morphology | Morphometrics
soft rays: 14;
Vertebrae: 26. This species differs from other pseudochromids in having the following set of characters: D III,24-25, usually III,24; A III,14; pelvic-fin rays I,5; anterior tip of palatine tooth patch directed medially behind posterolateral arm of vomerine tooth patch; upper part of body with dark (dark grey to black in life) longitudinal stripe, when present it is extending horizontally to or towards caudal-fin base; scales in lateral series 39-43; circumpeduncular scales 20-21, usually 20 (Ref. 89094).
This species is generally found around isolated, small coral and rock outcrops in both silty and clear water reef environments, usually in about 10-45 m depth (sometimes seen as deep as 60 m). Occurs solitarily or in small loose groups, is relatively curious and easy to photograph, though it invariably retreats into crevices or under coral heads when approached too closely (Ref. 89094).
