Mahunka, S.: Some oribatid mites from Yemen (Acari: Oribatida) (Acarologica Genavensia LXXXVIII)

Multioppia trembleyi MAHUNKA, 1977 The author described the species from the Seychelles (MAHUNKA 1977) as close relative of M. wilsoni AOKI, 1964 known from the Laysan Is. Later MAHUNKA (1992) also described a Multioppia species (M. calcarata MAHUNKA, 1992) from Senegal belonging in this relationship. The discovery of a population in Yemen make it imperative to re-examine the real differences existing among these species. Thorough examination revealed that the species from Seychelles, Senegal and Yemen are identical, consequently, M. calcarata MAHUNKA, 1992 is a junior synonym of M. trembleyi. Supporting evidences are in the sharp and pointed anterior outgrowth of pedotecta I, the sharp pedotecta II—III, as well as further identities in the epimeral region, like the extremely strong pair of tubercula on the sejugal borders, and that the medial epimeral borders are somewhat removed from each other. The notogastral setae are strongly arched and bear 2-3 well visible cilia. Whether wilsoni is also a synonym of trembleyi remains to be seen, although AOKI (1964) clearly states "notogastral setae smooth" and the species is figured Figs 13-15. Lasiobelba arabica sp. n.: 13 = femur of leg I, 14 = tarsus and tibia of leg IV, 15 = trochanter, femur and tibia of leg IV
