Anal
soft rays: 16 - 17;
Vertebrae: 41 - 42. This species belonging to the martinica species-group is distinguished from its congeners by the following characters: anus is between anal fin origin and pelvic fin insertion; tips of pelvic fins reaching the anterior margin of vent; posterior margins of predorsal and lateral scales are strongly laciniate; lateral scales 42-44; predorsal scales 20-22; length of spinous dorsal fin 8.5-9.5% SL; the least depth of caudal peduncle 7.3-8.6% SL (Ref. 123107).
The species was collected in open water, at night when lights were submerged below the
surface waters to 1 m off the R.V. Pilsbury. about 1 km offshore (Ref. 123107).
