Identification. A small species of dasyatid (maximal disc width less than 180 mm); snout elongate, forming a projecting tip; anterior disc margins slightly concave; eye small; large band of compact denticles running along centre of the disc to the tail sting; dorsal surface of the disc light grey-brown, paler on margins, ventral side of the disc white ( Carpenter and Niem 1999a).

Brevitrygon walga can be distinguished from all other stingrays occurring in this region by its large band of compact denticles running along centre of disc. A common coastal species in Southeast Asia regularly occurring in brackish environments. Generic classifica- tion follows Last et al. (2016); this species was previously classified in the genus Himantura (e.g., Weigmann 2011).
