Short Description
A species of Myliobatis distinguished by the following combination of characters: disc rhombic, wider than long, width about 2.2-times TL. Anterior margin of disc joining head behind orbits. Head clearly protruding from disc, eyes in lateral position and of moderate size. Snout width equal to interorbital distance, mouth relatively wide, as broad as distance between 5th gill slits; mouth width greater than distance between inner ends of nostrils. Distance between 5th gill slits greater than distance between inner ends of nostrils. Color in life: Dorsal surface dark-brown to dark-olive-green or orange-brown. Ventral surface whitish with darker-orange or black margins of pectoral fins. Lower surface of pelvic fins, claspers, and tail white. Tail paler near base; becoming darker to nearly black towards tip. [17160]
