The Queen of Sheba's Gazelle or Yemen Gazelle (Gazella arabica bilkis Groves & Lay, 1985), is an extinct subspecies of the the Arabian Gazelle, which is also extinct. It is sometimes regarded as a species in its own right: Gazella bilkis. It was found on the mountains and hillsides in Yemen but there have been no sightings of the species since 1951, when five specimens were collected in mountains near Ta'izz, where it was reportedly common at the time.
There have been no further specimens, sightings or reports of this gazelle. Surveys in the area of their former occurrence have failed to find any sign of its presence.
In 1985, a photograph of gazelles was taken in a private collection, Al Wabra Wildlife Farm, in Qatar. Zoologist Colin Groves claims these could possibly be surviving Queen of Sheba's Gazelles. It is not confirmed that these animals truly belong to this species.
