Latouchia is a genus of Asian mygalomorph spiders in the family Halonoproctidae, first described by Reginald Innes Pocock in 1901. The genus is presumably named in honour of John David Digues La Touche (who is named as "J. de La Touche" alongside "C. B. Rickett") as co-collector of the first described species Latouchia fossoria.
Originally placed with the family Ctenizidae, the genus was moved to the Halonoproctidae in 2018.
