Tamaulipas jackrabbit

The Tamaulipas jackrabbit, Lepus altamirae, also known as the Tamaulipas white-sided jackrabbit, is a species of hare endemic to the Gulf Coast of Mexico. It was formerly thought to be a subspecies of the black-tailed jackrabbit, but genetic analysis showed it to be a distinct species most closely related to the Tehuantepec jackrabbit, and it was reinstated as a separate species. Its very small range runs from the coastal plain of southern Tamaulipas south to extreme north Veracruz and west to the eastern border of San Luis Potosi, in the Tamaulipan mezquital ecosystem. No specimens were collected after 1898 until photographs in 2014, 2016 and 2021 confirmed that it persists, though it is feared to have lost much of its range.
