New Landrevinae from Mascarene islands and little known Landrevinae from Africa and Comoros (Grylloidea: Landrevinae)

Abstract

Landrevinae from Africa and south western Indian ocean (SWIO) islands are examined, seven new species and one new genus are described from la Réunion and Mauritius islands: Microlandreva parvotibialis n. sp., Creolandreva aptera n. g., n. sp., C. crypta n. sp., C. chaloupensis n. sp., C. crepitans n. sp., C. cocottensis n. sp., C. pollexensis n. sp. and C. brachyptera n. sp. Genitalia from Microlandreva notabilis Chopard 1958 and Oreolandreva brevipennis Chopard 1945 are illustrated and a description complement of thoracic glands and ovipositor is given. Gryllapterus tomentosus Bolivar 1912 described after an immature female was considered as a Landrevinae but is in reality a Phalangopsinae. The geographical origin of Paralandrevus hector (Saussure 1877) is corrected: erroneously described from Réunion, P. hector is in reality from Maluku islands. Relations between Landrevinae from Africa and SWIO islands are discussed. A key of Landrevinae from Africa and SWIO islands is given.
