Hemitrygon is a genus of stingrays in the family Dasyatidae from marine, brackish and freshwater habitats in the central Indo-Pacific and northwest Pacific regions. The genus was formerly regarded as a junior synonym of the genus Dasyatis.[1]
Species
[edit]The taxonomy of Hemitrygon requires revision, as some existing species may be synonyms and there may be undescribed species. H. yemenensis was described in 2020 from materials collected nearly 120 years ago and its status in the wild is unknown.[2]
