the earlier described species. See also the remarks after the description of the last newly described Zygoribatula species. From zoogeographical point of view the Oribatida fauna of the peninsula is strongly mixed. Still we may not say that the southern territories, where Yemen lies, in fact belong to the Ethiopian region. There are numerous Palaearctic elements here, as for example Cosmochthonius lanatus, Cryptacarus promecus, Dometorinaplantivaga, Scheloribates fimbriatus, Haplozetes vindobonensis. Naturally these species have a wide distribution in the Mediterranean region. Peculiarly enough, real Ethiopian elements are rather rare, like Basilobelba retiaria and Multioppia trembleyi, on the other hand, we find here circumtropical species in abundance. This latter group is represented by such species as Microtritia tropica, Chaunoproctus pedestris, Rostrozetes ovulum, Lamellobates molecula, Paralamellobates misella and Galumna flabellifera. This fenomenon is also well reflected by the new species, particularly their generic range. All in all this fauna may better be described as tropical, rather than Palaearctical. The descriptions and the terminology applied in this contribution follow those of my previous papers (cf. MAHUNKA 1994).
