A TAXONOMIC REVISION OF THE ORIBATID MITE GENUS CAMISIA (ACARI, ORIBATIDA)

Nine new species of Camisia are described from adult female material (C. dictyna sp. nov., C. grymae sp. nov., C. nortoni sp. nov., C. oregonae sp. nov., C. presbytis sp. nov., C. tryphosa sp. nov. and C. valeriae sp. nov.): C. labradorica Behan, 1978 was found to be a1 junior synonym of C. lapponica Tragardh, 1910. C. lapponica Tragardh sensu Sellnick and Forsslund, 1955 is a1 different species from C. lapponica Tragardh, and is described as new under the name Camisia solhoeyi sp. nov. Camisia borealis (Thorell) sensu Tragardh (1904) was found to include two species; C. borealis (Thorell), for which a1 neotype is designated, and a1 species described as new under the name Camisia anomia sp. nov. The following species are redescribed or given supplementary descriptions: C. arcuata Hammer, 1961; C. australis Hammer, 1958; C. biurus (C. L. Koch, 1839); C. biverrucata (C. L. Koch, 1839); C. borealis (Thorell, 1871); C.foveolata Hammer, 1955; C. hamulifera Hammer, 1961; C. horrida (Hermann, 1804); C. invenusta (Michael, 1888); C. khencensis Hammer, 1961; C. segnis (Hermann, 1804) and C. spinifer (C. L. Koch, 1835). C. segnis nova Hammer, 1958 is re-described and given specific status. Five species-groups ('hamulifera', 'segnis', 'spinifer', 'invenusta' and 'horrida') are described, based on the morphology of the lamellar apophyses and setae, interlamellar setae, posterior notogastral setae and their apophyses and the arrangement of folds, plates, setae and apophyses of the caudal region. A1 key to recognizable species of Camisia of the world is provided.
