Short Description
Original Diagnosis after LAST, WHITE & SÉRET, 2016 [23790]: A large Neotrygon of the kuhlii-complex (reaching at least 45 cm DW; males maturing at ~28 cm DW) with the following combination of characters: disc much broader than long, width 1.2–1.3 times length; pectoral apices narrowly angular; snout fleshy, broadly rounded to weakly angular, angle 101–103°, length 1.6–2.1 times interorbital width; maximum width relatively well back on disc, length from snout tip to pectoral-fin insertion 1.7–1.8 times and disc width 2.3–2.5 times horizontal distance from snout tip to maximum disc width; preoral length 1.8–2.3 times mouth width; internasal distance 1.3–1.6 in prenasal length; interspiracular distance 14–16% DW; nostril length 3.4–4% DW; nasal curtain width 8.4–9.1% DW; small mouth, width 6.5–7.3% DW; horizontal distance from cloaca to caudal sting base 42–52% of disc length; thornlets present in nuchal and lumbar regions in large individuals, absent from tail in all sizes; dermal denticles entirely absent from body; pectoral-fin radials 105–113; total vertebral centra (including synarcual) 129–134, trunk centra (including synarcual) 37–41; blue spots large, largest spot on disc 0.7–1.2 times eye width; 2–17 (mean 9.4) blue spots on medial belt, largest 3.3–5.6% DW; mask-like marking subtle, usually lightly covered with dark peppery spots (dark spots not widespread over central disc); ventral surface of disc with distinct dark greyish brown submarginal bands; ventral tail fold almost entirely dark.
