Short Description
Original diagnosis after MANJAJI-MATSUMOTO & LAST, 2016 [24334]: A species of Maculabatis (to at least 63 cm DW) distinguished by a combination of the following characters: disc broadly rhomboidal, length 89–93% DW; snout moderately elongate with small apical lobe, snout angle 113–121°; pectoral-fin apices narrowly rounded; orbits small, protruding slightly; mouth relatively narrow, width 1.1–1.6 in internasal width; distance between first gill slits 2.1–2.3 times internasal distance; distance between fifth gill slits 1.4–1.5 times internasal distance, 28–30% of ventral head length; pelvic-fin base narrow, 12–13% DW; small yellow, seed-shaped suprascapular denticle followed by a slightly larger white, heart-shaped denticle; weak primary denticle band present in young but soon becoming inconspicuous; secondary denticle band irregularly suboval, relatively narrow with well-defined lateral margins, rounded forward of orbit and not extending lateral to orbit even in large adults; band broad near tail base in adults; dorsal disc uniformly brownish (lacking white spots); ventral disc pale with broad, weakly-defined and slightly darker margins; anterior tail lightbrown on dorsal surface and usually without white lateral spots; tail banded dorsally behind caudal-sting base, bands more obscure or absent with age; pectoral-fin radials 127–135; total vertebral count, including synarcual centra 102–111, monospondylous centra 41–47, pre-sting diplospondylous centra 55–68.
