Abstract

A new species of oribatid mite of the family Galumnidae, Pergalumna sistanbaluchestanica sp. nov., is described and illustrated based on adult specimens from soil in Sistan and Baluchestan province, southeastern Iran. The new species is characterized by dentate rostrum; long interlamellar setae; long, setiform, finely barbed bothridial setae; complete dorsosejugal furrow; large, nearly triangular porose areas Aa; presence of median pore in females and males; large, elongated postanal porose area and large body size. The new species is most similar morphologically to P. seminervosa Mahunka & Mahunka-Papp, 2008, however, differs from it in morphology of bothridial setae and notogastral porose areas Aa and also by the surface ornamentation of the pteromorphs and genital plates; localization of setal alveoli la and lyrifissures im and body size. An identification key to known species of Pergalumna from the Palaearctic region is given.
