The terrestial Orchestia from Tenerife (Canary Islands), currently recorded as O. chevreuxi De Guerne, 1887, is compared with material from the terra typica, the island of Faial in the Azores. It is concluded that the Tenerife populations belong to a different species, which we describe as O. guancha n. sp., whereas O. mateusi Afonso, 1977 is considered a junior synonym of O. chevreuxi (new synonymy).
