Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 12; Épines anales: 1; Rayons mous anaux: 11; Vertèbres: 27. This species differs from its congeners in having the following set of characters: D VI-I,12; A I,11; pelvic-fin rays I,5 with the innermost (= fifth) segmented pelvic-fin ray unbranched, long, subequal to preceding ray in length; elongated body, depth at anal-fin origin 11.9% of SL; cycloid scales, restricted on posterior part of body (ca. 14-15 longitudinal scales); sensory canals and associated pores on head absent (Ref. 84003).
The holotype, a mature female with numerous developed eggs in the ovary, was dredged at
53 m depth. No habitat information is known (Ref. 84003).
