Short description Morphology | Morphometrics

Dorsal soft rays (total): 14. This species is distinguished from its congeners by the following set of characters: 28 tail rings; 14 dorsal fin rays; 9 pectoral fin rays; 4 subdorsal rings; bilaterally paired wing-like protrusions are formed by a pair of large truncate spines projecting laterad on first superior trunk ridge; elevated dorsal ridge is formed by unique triangular bony mounds dorsally on second, the third and fourth trunk rings with the posterior mound less pronounced; a large and prominent spine projecting laterad on eighth lateral trunk ridge (Ref. 118476).

This species was not associated with a particular host. It has been observed in association with mixed soft coral, Halimeda sp. (coralline algae) and hydroids on rocky reef walls and large boulders in both exposed and semi-sheltered locations (Ref. 118476)..
