A guide to Oribatid Identification for the ABMI: - Royal Alberta Museum

Almanac of Alberta Oribatida 2.3 13 January 2013PlatesBelow are three plates showing some of the morphological characters used to identify oribatidmites. An important point to remember is that every seta (hair) on the body and legs of anoribatid mite has a special designation and, generally, also a name. For example, the interlamellarseta is in (note italic font is used for setal designations), the lamellar seta is le, and the rostral setais ro. The bothridial sensillus is designated ss in some literature, but bo (for bothridial seta) in theAlmanac. Setal designations can also refer to the body region in which they are inserted. Forexample, in, ro, le, and bo are prodorsal setae; c2 and la are notogastral setae.16
