Short Description
Original diagnosis of Glaus, White, O'Neill, Thurnheer & Appleyard, 2025 [34543]: A large-sized Neotrygon of the kuhlii complex (reaching up to 400 mm DW) with the following combination of characters: disc broader than long, width 1.1–1.2 times length; pectoral apices subangular; snout rather fleshy, broadly angular, angle 122–130°, length 1.5–2.1 times interorbital width; maximum width relatively well back on disc, length from snout tip to pectoral-fin insertion 1.7–1.8 times horizontal distance from snout tip to maximum disc width; preoral length 1.6–2.1 times mouth width; internasal distance 1.3–1.7 in prenasal length; interspiracular distance 13.1–14.4% DW; nostril length 3.0–5.2% DW; nasal curtain width 8.9–10.0% DW; small mouth, width 7.1–8.5% DW; horizontal distance from cloaca to caudal sting base 41–52% of disc length; thornlets present in nuchal region, at least some widely spaced denticles on tail; well-spaced denticles present on dorsal disc mostly in the median band region; pectoral-fin radials 107–111; total vertebral centra (including synarcual) 128–142, monospondylous centra (including synarcual) 39–47. Dorsal surface medium brown with sparsely populated with small pale blue to whitish spots, largest spot on disc 0.3–0.4 times eye width; 0–2 (mean 0.6) blue spots on medial belt, largest 1.2–1.6% DW (when present), and peppered with numerous small black spots; mask-like marking pronounced, more densely covered with black peppery spots; darker branchial blotches here. Ventral surface of disc and pelvic fins pale with broad dark greyish submarginal bands; tail posterior of pelvic fins bluish grey in live specimens.

Dentition
Teeth uniformly close-set in both jaws, in oblique rows; tooth files (in paratype CSIRO H 9640–07) in upper jaw approximately 25, lower jaw 33. Upper jaw strongly arched, strongly double convex; teeth of anterior part of upper jaw concealed when mouth closed [34543]
