Five specimens were obtained from a fish buyer, but three individuals were processed and sold, while two others were kept for research; two egg capsules (EBFS020204010602-3) from 1 of 3 processed individuals were also retained and are deposited with the two intact specimens.

Diagnosis. Snout moderately short and broadly rounded, 2/3 of mouth width; nasal flaps large, narrow-based and lobate; gill septa not excavated and concave posteriorly. First dorsal fin about as large as second; first dorsal origin just behind pelvic origins; first dorsal insertion slightly behind pelvic insertions; second dorsal smaller than anal fin; second dorsal origin well behind anal origin; second dorsal insertion about over anal insertion; ventral edge of caudal peduncle and preventral caudal margin with a crest of enlarged denticles.
