Short Description
Original diagnosis after SÉRET, 2016 [24713]: Diagnostic characters: A large guitarfish with a triangular disc and shark-like tail, snout pointed and typically wedge-shaped. Tail with a dermal fold along each lower edge. Two large and falcate dorsal fins; caudal fin with distinct upper and lower lobes. Two dermal folds on posterior margin of spiracles. Nostrils very large and oblique, separated from each other and from the mouth; nasal valves small. About 42 to 46 / 54 to 56 rows of oral teeth arranged in pavement. A row of pointed thorns along each rostral ridge, 2 additional thorns may occur on snout tip, a patch of thornlets and thorns in front of orbit extending backward to level of spiracles as a simple row; a median row of large pointed thorns from nape to first dorsal fin and between dorsals, flanked by 2 other short rows on the nape-shoulder area, additional short rows of thorns may be present on outer shoulders. Body covered in small dermal denticles, their crown with a median posterior cusp prolonging a median ridge and short lateral cusp. Colour: more or less yellowish above with a pattern of numerous circular dark-rimmed white spots, 2 large backish blotches (sometimes 4) on shoulders, placed between the 3 rows of thorns; alternating pale and dark crossbars may occur on the interorbital space; lower side white, with a large transverse blackish blotch on snout. Number of trunk vertebrae 44 to 49; number of pectoral radials 71 to 77.

Biology
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures [733].
