The blackish stingray (Hemitrygon navarrae) is a little-known species of stingray in the family Dasyatidae, found in the northwestern Pacific Ocean off the coasts of mainland China and Taiwan. This species reaches 38 cm (15 in) across and has a chocolate brown, diamond-shaped pectoral fin disc nearly as long as wide. Its whip-like tail bears three large tubercles in front of the stinging spine, as well as both dorsal and ventral fin folds with the ventral fold half as long as the disc.
