==Description==
The Java stingaree has an oval [[pectoral fin]] disc slightly longer than wide; the leading margins are gently convex and converge at a blunt angle on the snout. The eyes are followed by larger, comma-shaped [[Spiracle (vertebrates)|spiracle]]s. The nostrils are crescent-like, and between them is a curtain of skin with a minutely fringed posterior margin. The mouth is bow-shaped, and contains three papillae (nipple-like structures) on the floor. The teeth are closely arranged with a [[quincunx]] pattern; each is small with a transverse ridge on the crown. The five pairs of [[gill slit]]s are short. The [[pelvic fin]]s are almost square, with rounded corners. The tail is shorter than the disc and bears a prominent [[dorsal fin]] about halfway along its length; immediately posterior to the dorsal fin is a serrated stinging spine. The tail ends in a leaf-shaped [[caudal fin]], whose dorsal origin lies behind the ventral origin. The skin is devoid of [[dermal denticle]]s, though there are tiny white bumps on the upper central portion of the disc. This species is dark brown above, with many indistinct darker and lighter spots, and pale below. The sole specimen measures {{convert|33|cm|in|abbr=on}} long.<ref name="martens"/><ref name="last and compagno"/>
