Short Description
Original diagnosis of LAST, 2008 [3310]: A very small species of Dipturus (to about 37 cm TL) with the following combination of characters: disc narrow with rounded apices, width 62– 69% TL, 1.1–1.2 times its length; snout angle 79–93°; tail moderately elongate, length 0.8–1.0 in distance from snout tip to rear of cloaca; tail relatively broad, width 1.4–2.1 times height at its midlength, 1.6–2.3 times at first dorsal-fin origin; pre-upper jaw length 15–18% TL, 1.9–2.3 times internasal width; ventral head length 30– 32% TL; snout length 4.0–4.4 times interorbital width; orbit diameter 98–129% interorbital width; first dorsalfin height 1.3–1.7 in its base length; distance from first dorsal-fin origin to tail tip 2.8–3.0 times first dorsal-fin base length, 1.2–1.7 times caudal-fin length; pelvic fins large, length of posterior lobe of adult males about 20% TL, length of anterior lobe 56–76% of posterior lobe; clasper of adult male long, about 24–26% TL, connected to pelvic-fin inner margin at about 37–44% of its length from cloaca; anterior margins of dorsal surface with narrow denticle bands, naked ventrally; mainly with a single nuchal thorn; malar thorn patch small; tail with 3 well-developed thorn rows in males, with an additional pair of lateral rows in females; total pectoral radials 76–81; trunk centra 26–29; predorsal centra 69–77; total centra about 112–124; tooth rows in upper jaw 33–44; brownish dorsally with widely spaced clusters of small black and white spots; ventral surface pale, plain coloured; sensory pores on ventral surface black-edged with small dusky surrounding patches.
