Short description Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 26; Anal spines: 3; Anal soft rays: 16. Distinguished from all other pseudochromines by the following characters: dorsal-fin rays III,26; anal-fin rays III,16; anal-fin spines moderately slender and weakly pungent, the second spine only slightly stouter than the third; lower lip weakly interrupted at symphysis; and circumpeduncular scales 16. It also has a distinctive live coloration: head orange-brown, becoming bright yellow on lower part of operculum; posterior and ventral part of orbital rim bright yellow, edged posteriorly and ventrally by purple-blue arc; scales of cheek indistinctly edged with mauve; body orange-brown, darker on scale-edges, becoming bright yellow on breast and pectoral-fin base, bright red on abdomen and above anterior anal fin, then dark purplish red on caudal peduncle; dorsal fin golden to orange-brown anteriorly, becoming reddish brown posteriorly, with reddish brown distal margin; 1-3 rows of short, dark reddish brown streaks on middle of soft portion of fin; anal fin dark reddish brown, becoming golden brown over spinous portion of fin, with grey distal margin; caudal fin dark reddish grey basally, abruptly greyish hyaline on distal third of fin, with grey distal margin (Ref. 80681).

Solitary under large Xestospongia barrel sponges on gradual, current-swept reef slopes in 32-45 m, sometimes in pairs (Ref 90102).
