A Revision of the genus Temnus Fleutiaux (Coleoptera, Eucnemidae, Galbitini)

Four genera are transferred from the tribe Mesogenini to Galbitini: Temnus Fleutiaux 1920, Temnillus Bonvouloir 1871, Submesogenus Fleutiaux 1921 and Arisus Bonvouloir, 1871. The evolutionary history of the tribes Eucnemini, Galbitini and Mesogenini is discussed. The genus Temnus is revised. Four new species are described: T. ischigachiensis n.sp. (Japan), T. thai n. sp. (Thailand), T. papuensis n. sp. (Papua New Guinea) and T. punctithorax n. sp. (Papua New Guinea). Three species are redescribed: T. alius (Fleutiaux 1912), T. differens (Fleutiaux, 1912) and T. sumatrensis (Fleutiaux 1896). The habitus and the male genitaliae of all the species are illustrated and a key to identify the species is given.Peer reviewe
