This small, blue-spotted stingray is distinguished by the following characters: absence of a pair of blue longitudinal stripes along the sides of the tail; uniformly pale ventral fold; absence of the dorsal fold but upper margin of tail with a firm, blunt ridge; a relatively short post-orbital disc (length from rear of orbit to pectoral-fin insertion 63-65% WD), with a relatively long horizontal snout length (20-21% DW) and prenasal length 14-16% DW, and prenasal length 1.5-1.9 times internasal width (Ref. 110363).
This species probably occur mainly inshore, with types collected from surge channels in fringing coral reefs, to at least 18 m depth (Ref. 110363)..
