Holotype female, RUSSIA : Voronezh Province, Voronezh, in litter under coniferous, 30 October 1972, coll. N.N. Kuznetsov. Type deposition . The holotype is deposited in the mite collection of the Nikita Botanical Gardence, Yalta, Crimea, Russia. Remarks . The female holotype is in rather bad condition, especially idiosoma and I provided only supplementary description because some body structures are almost invisible. The dorsal body setae are not so heavily barbed as in the original description. Setae c 2 are situated on the humeral shield instead out of the shield in the original description. : Published as part of Khaustov, Alexander A., 2014, A new species of the genus Paravillersia (Acari: Prostigmata: Stigmaeidae) from Western Siberia, with supplementary description of Paravillersia grata Kuznetsov, 1978 in Zootaxa 3873 (1) , DOI: 10.11646/zootaxa.3873.1.5, http://zenodo.org/record/228781
