NEW RECORDS OF PREDATORY MITES OF THE GENUS STIGMAEUS (ACARI: PROSTIGMATA: STIGMAEIDAE) FROM WESTERN SIBERIA WITH THE REDESCRIPTIONS OF S. DIGNUS KUZNETSOV AND S. UZUNOLUKENSIS ÖZÇELIK AND DOĞAN

Abstract

During a study of predatory mites of Western Siberia, I have recorded the following six species of the genus Stigmaeus (Acari: Stigmaeidae): S. dingus Kuznetsov; S. uzunolukensis Özçelik and Doğan; S. harsitensis Doğan, Doğan and Erman; S. fimus Doğan, Doğan and Erman; S. corticeus Kuznetsov; and S. pilatus Kuznetsov. These species were recorded for the first time from Asian Russia. Moreover, three of the six species—S. uzunolukensis, S. harsitensis and S. fimus—have been recorded for the first time from Russia as well. This article redescribes females of S. dingus and S. uzunolukensis based on materials from Western Siberia. Also, a S. uzunolukensis male is described for the first time.
