Short Description
Original Diagnosis of LAST, WHITE & POGONOSKI, 2008 [3309]: A medium-sized species of Dipturus (to 72 cm TL) with the following combination of characters: disc relatively broad with narrowly rounded to angular apices, width 64–68% TL, 1.1–1.2 times its length; snout angle 64–74°; tail length 0.8 in distance from snout tip to rear of cloaca; tail slender, somewhat rounded in crosssection, width 1.5–1.8 times height at its midlength, 1.5– 1.8 times at first dorsal-fin origin; pre-upper jaw length 19–22% TL, 2.3–2.7 times internasal width; ventral head length 33–35% TL; snout length 3.9–4.6 times interorbital width; orbit diameter 53–85% interorbital width; first dorsal-fin height 1.6–2.4 in its base length; distance from first dorsal-fin origin to tail tip 2.8–3.2 times first dorsal-fin base length, 2.2–3.2 times caudalfin length; pelvic fins of medium size, length of posterior lobe of adult males 17–18% TL, length of anterior lobe 69–74% of posterior lobe; adult clasper elongate, 27– 28% TL, connected to pelvic-fin inner margin at about 32–33% of its length from cloaca; anterior margins of both surfaces of disc of adult males with bands of granular denticles, dorsal bands absent in juveniles and large females; nuchal thorns usually absent (single weak thorn occasionally present); malar thorn patch small; tail usually with a single thorn row in males, 1–2 additional pairs of variably developed lateral rows in females; total pectoral radials 74–79; trunk centra 26–30; predorsal centra 76–84; total centra about 121–128; tooth rows in upper jaw 34–40; uniformly pale yellowish brown dorsally; greyish centrally with a paler outer disc and tail ventrally; gill membranes whitish, strongly demarcated from adjacent ventral head; ventral sensory pores small, distinct, black-edged, sometimes surrounded by small dusky blotches.
