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).[1]

Species

There are four valid species:[2]

A fifth species, Himantura tutul (fine-spotted leopard whipray), has been described,[3] but its validity has been disputed [4] and it is somewhat arbitrarily considered a junior synonym of H. uarnak by the Catalog of Fishes.[2] The Catalog of Fishes chose to synonymize H. tutul with H. uarnak, despite the fact that H. tutul was previously confused not with H. uarnak, but with H. leoparda, and subsequently shown to be reproductively isolated from both H. uarnak and H. leoparda.[5][6] While adult H. uarnak typically present solid spots only, both adult H. leoparda and H. tutul are distinct from it by the presence of leopard-like ocellated spots, which are smaller and less numerous in H. tutul.[3][5][6]
