Himantura

Himantura is a genus of stingray in the family Dasyatidae that is native to the Indo-Pacific. In a 2016 taxonomic revision, many of the species formerly assigned to Himantura were reassigned to other genera (Brevitrygon, Fluvitrygon, Maculabatis, Pateobatis, Styracura and Urogymnus).

Species
Twelve extant species are currently recognized as valid, formerly four or five species.

The former contentious species, Himantura tutul has had its validity disputed and has been considered a junior synonym of H. uarnak by the Catalog of Fishes. However, H. tutul was previously confused not with H. uarnak, but with H. leoparda, and subsequently shown to be genetically distinct and reproductively isolated from both H. uarnak and H. leoparda. Both adult H. leoparda and H. tutul present leopard-like ocellated spots. These are smaller and less numerous in H. tutul.
