Glomeremus species from the Mascarene islands (Orthoptera, Gryllacrididae) with the description of the pollinator of an endemic orchid from the island of Reunion

摘要

Glomeremus Kamy, 1937 species from the Mascarene islands are examined. One new species is described from Reunion: G. orchidophilus n. sp.. Two new species are described from Mauritius: G. paraochidophilus n. sp. and G. tikasignatus n. sp.. The case ofG. shelfordi (Griffmi, 1909) supposedly described from Mauritius is discussed as well as the likely polyphyly of the genus Glomeremus. G. orchidophilus n. sp. is the only pollinator of the Orchid Angraecum cadetii on Reunion, representing the first supported case of regular pollination by an insect from the order Orthoptera in extant flowering plants. The possible involvement of Mauritian Glomeremus in A. cadetii pollination on Mauritius is discussed.
