Short description

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Vertebrae: 34 - 35. Apparently a small species with a deep body, approximately equal to head length. Eye very large, greater than snout length. Snout blunt; mesethmoid greatly enlarged, more strongly projecting ventrally when compared with congeners. Tympanum large, its width equal to eye diameter. Swim bladder chamber with a greatly expanded dorsal bony roof but no ventral bony enclosure. Jaws with well-developed conical teeth in several irregular rows. Cranial roofing bones more superficial than in any other Nangrina, and covered with thin skin; cranial surface rugose. Posterior cranial fontanel very small, less than 1/3 length of anterior fontanel; lateral fontanels absent; subtemporal fossa absent. Anal fin with 4-5 simple rays, 8-10 branched rays (Ref. 40780).
