Somali elephant shrew

The Somali elephant shrew or Somali sengi ("Galegeeska revoilii") is a species of elephant shrew in the family Macroscelididae.
Natural habitat.
Its natural habitat is arid and semiarid desert with rocky substrates and sparse shrubs. In some parts of Somalia, the Somali sengi and rufous sengi may be locally sympatric. It is found in the northern Horn of Africa; it was formerly thought to be exclusively endemic to Somalia, but a 2020 sighting also indicates they are found in Djibouti and potentially Ethiopia.
Classification.
It was formerly classified in the genus "Elephantulus", but a 2020 study found it to be the sister taxon of the clade containing the genera "Petrodromus" and "Petrosaltator"; due to this, it was reclassified in the monotypic genus "Galegeeska." The split with the "Petrodromus"-"Petrosaltator" clade is estimated to have occurred about 20.6 million years ago.
Disappearance and rediscovery.
The Somali sengi was among the 25 "most wanted lost" species that were the focus of Global Wildlife Conservation's “Search for Lost Species” initiative. On , 50 years after it was last seen and recorded, it was announced that a population had been found in Djibouti, the first documented since 1968.
Etymology.
"Galegeeska" translates to "weasel of the horn". In the Somali language, 'geeska' means corner or horn, as in the Horn of Africa. Galê in Ancient Greek means weasel, and has been used in other small mammal taxa. 'Gale' also honours one of the authors, Galen B. Rathbun (1944-2019) who searched for the Somali sengi and devoted several decades of research into sengi biology.
