Morphology | Morphometrics
Tip of pectoral girdle propterygium well separated from rostral node by about a half of rostral cartilage length. Preorbital snout long, 20% (holotype) and 21% (paratype) TL; rostral shaft straight, wide and stout; anterior fontanelle with distinct anterior margin. A single
scapular thorn on each side; three or four nuchal thorns; a row of lumbar thorns along dorsal midline of disc. Tail thin, narrow, slightly depressed, its length short as 45% (holotype) and 43% (paratype) TL; a single row of distinct thorns along dorsal midline in both sexes. Scapulocoracoid without anterior bridge; anterior fenestra strongly anteroposteriorly elliptical; postventral fenestra expanded horizontally; mesocondyle located at about middle between
procondyle and metacondyle. Pelvic girdle with three pairs of obturator foramina. Pores of ampullae of Lorenzini extending to just before pelvic girdle. Clasper glans with cleft, terminal bridge, shield and rhipidion; dermal denticles
absent. Tooth rows 36 (holotype) and 32 (paratype) in upper jaw. Trunk vertebrae 27; predorsal caudal vertebrae 47. Pectoral radials 92 on each side (Ref. 75712).
A demersal species with unknown capture depth, probably continental slope below 200 m. Occasionally found at regional fish markets with few retained by museums (Ref. 114953).
