Collections of oribatid mites from Southern Portugal, with description of a new species of Oribatula (Acari: Oribatida: Oribatulidae)

Abstract

In the course of studies of oribatid mites from 12 localities of southern Portugal we found representatives of 121 species, 77 genera, and 45 families, of which 63 species/subspecies are registered for the first time for Portugal. A checklist, collection localities and known distribution of these species are presented. A new species, Oribatula polytuberculata sp. n., is described and illustrated; it is clearly distinguishable from all other species of the genus by having a tuberculate notogastral surface.
