Short Description
Original Diagnose of LAST, WHITE & POGONOSKI, 2008 [3309]: A medium-sized species of Dipturus (to 78 cm TL) with the following combination of characters: disc very broad with angular apices, width 71–80% TL, 1.3–1.4 times its length; snout angle 72–82°; tail length 0.8–0.9 in distance from snout tip to rear of cloaca; tail slender, somewhat rounded in cross section, width 1.3–1.7 times height at its midlength, 1.4–1.9 times at first dorsal-fin origin; pre-upper jaw length 17–23% TL, 2.3–2.8 times internasal width; ventral head length 32– 36% TL; snout length 4.2–5.6 times interorbital width; orbit diameter 73–97% interorbital width; first dorsalfin height 1.7–2.3 in its base length; distance from first dorsal-fin origin to tail tip 3.2–3.8 times first dorsal-fin base length, 2.7–3.5 times caudal-fin length; pelvic fins small, length of posterior lobe of adult males 15–16% TL, length of anterior lobe 67–71% of posterior lobe; adult clasper relatively elongate, 23–25% TL, connected to pelvic-fin inner margin at about 40–44% of its length from cloaca; anterior margins of both surfaces of disc with a narrow band of granular denticles (band absent from dorsal surface of large females and juveniles); no nuchal or malar thorns; tail with a single thorn row in both males and females; total pectoral radials 92–98; trunk centra 29–32; predorsal centra 77–86; total centra 136–140; tooth rows in upper jaw 32–37; mainly uniformly greyish brown dorsally; mostly greyish brown (not blotchy) ventrally, gill membranes not paler than adjacent head; anteroventral margin of disc distinctly whitish (on denticle band), outer half black-edged (areas very strongly contrasted in juveniles); ventral sensory pores black-edged, not surrounded by dusky blotches, prominent on snout; epichordal lobe blackish.
