Short Description
Original diagnosis after LAST, STEHMANN & SÉRET, 2008 [3315]: A medium-sized species of Leucoraja (to 40 cm TL) with the following combination of characters: disc narrow, inverted heart-shaped to subcircular with broadly rounded apices, width 54–60% TL, 1.1–1.2 times its length; snout angle 90–104°; tail elongate, tapering, length 1.0–1.1 times distance from snout tip to rear of cloaca, relatively slender, width 1.7–1.9 times height at its midlength, 1.7–1.9 times at first dorsal-fin origin; pre-upper jaw length 13–14% TL, 1.7–2.0 times internasal width; ventral head length 25– 28% TL; snout length 2.7–3.4 times interorbital width; orbit diameter 88–100% interorbital width; first dorsal fin usually connected to second dorsal fin, its height 1.8–2.6 in its base length; distance from first dorsal-fin origin to tail tip 2.1–2.7 times first dorsal-fin base length, 1.6–4.3 times caudal-fin length; pelvic fins of medium size, length of posterior lobe of adult males 17–20% TL, length of anterior lobe 61–70% of posterior lobe; adult clasper relatively short and stout, 21–24% TL, connected to pelvic-fin inner margin at about 38–46% of its length from cloaca; dorsal disc very spiny, almost wholly covered with fine denticles, thorns and thornlets; nucho–scapular thorn patch dense and triangular; rostral and interorbital thorns present in all but smallest juveniles; malar thorn patch well developed and located at level of orbit and spiracle; alar patch elongate, narrow, only slightly shorter than prespiracular length; tail with multiple irregular thorn rows (thorns of median row usually smaller than those of adjacent lateral rows); total pectoral radials 61–64; trunk centra 26–28; predorsal centra 85–91; total centra about 121–127; tooth rows in upper jaw 47–55; uniform pale greyish or brownish dorsally, uniformly whitish ventrally; ventral sensory pores not black edged; dorsal fins of juveniles pale based with black outer margins (less distinct in adults).
