Vertebrae: 108-114. This species (size at least 66 cm DW) is distinguished by the following set of characters: disc is weakly rhomboidal to suboval, its length 93-98% DW; snout is moderately elongate with weak apical lobe, snout angle 116-121°; pectoral-fin apices are broadly rounded; orbits small to medium-sized, barely protruding; relatively narrow mouth, its width 1.2-1.3 in internasal width; distance between first gill slits is 2.2-2.5 times internasal distance; distance between fifth gill slits is 1.4-1.6 times internasal distance, 28-30% of ventral head length; pelvic-fin base is broad, 14-15% DW; main suprascapular denticle is large, yellowish, broadly ovate, usually followed by smaller subtriangular denticle; secondary denticles developing rapidly, forming a broad band extending from interorbit to tail base by 24 cm DW; dorsal disc uniformly light brown, without white spots; pale ventrally with broad, faint and slightly darker lateral margins; tail dark brown to blackish dorsally and white ventrally forward of caudal sting; plain blackish posteriorly or with weak, irregular pale dorsal banding (in young); pectoral-fin radials 127-131; total vertebral count, 108-114, including synarcual centra, monospondylous centra 44-46, pre-sting diplospondylous centra 64-69 (Ref. 110187). |
| Smallest specimen, immature male at 20 cm WD is postnatal; birth size unknown, but probably ca. 15.0-17.0 cm WD (Ref. 110187). |
