A TAXONOMIC REVISION OF THE ORIBATID MITE GENUS CAMISIA NACARI, 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. orego nae sp. nov., C. presbytis sp. nov., C. tryphosa sp. nov. and C. valer iae sp. nov.): C. labradorica Behan, 1978 was found to be a1 junior sy nonym of C. lapponica Tragardh, 1910. C. lapponica Tragardh sensu Sell nick and Forsslund, 1955 is a1 different species from C. lapponica Tra gardh, and is described as new under the name Camisia solhoeyi sp. nov . Camisia borealis (Thorell) sensu Tragardh (1904) was found to includ e two species; C. borealis (Thorell), for which a1 neotype is designat ed, and a1 species described as new under the name Camisia anomia sp. nov. The following species are redescribed or given supplementary desc riptions: C. arcuata Hammer, 1961; C. australis Hammer, 1958; C. biuru s (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. khencensi s 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', 'inv enusta' and 'horrida') are described, based on the morphology of the l amellar apophyses and setae, interlamellar setae, posterior notogastra l setae and their apophyses and the arrangement of folds, plates, seta e and apophyses of the caudal region. A1 key to recognizable species o f Camisia of the world is provided.
