Taxonomic revision of the genus Machleida Fahraeus, 1870 (Tenebrionidae, Pimeliinae, Asidini)

The taxonomic concept of the genus Machleida Fahraeus, 1870 is tested and revised based on newly identified material. The following new species are described: Machleida banachi, M. flagstaffensis, M. tarskii, and M. zofiae Kaminski. Machleida capillosa Wilke, 1925 is considered as a junior subjective synonym of Asida devia Peringuey, 1899. Asides lecta Peringuey, 1899 (= Pseudomachla recurva Wilke, 1925) (transferred to Afinsida), Machleida nossibiana Fairmaire, 1897 (transferred to Scotinesthes), and Machleida tuberosa Wilke, 1925 (interpreted as incertae sedis in Asidini) are excluded from Machleida. An identification key for the species of the newly revised Machleida is provided. The present paper brings the total number of species within the genus to six (M. banachi sp. nov.; M. devia (Peringuey, 1899): M. flagstafensis sp. nov.; M. nodulasa Fahraeus, 1870; M. tankii sp. nov.; M. zofiae Kaminski sp. nov.). The morphology of female terminalia (ovipositor and genital tubes) is described for the genus for the time.
