Abstract

We redefine the subfamily Arctoseiinae of the family Ascidae, and describe a new genus, Maxinia gen. n., based on a new species, Maxinia arctomontana sp. n., whose adults display a combination of attri-butes uniquely different from other genera of the subfamily. The geographical range of M. arctomontana is limited by arctic and mountain landscapes of Siberia. This description provides further data on the arctic distribution and morphological diversity of the subfamily Arctoseiinae, which is unusually well represented in that region (26–83 % in local gamasid mite faunas). Conceptual problems with the genus Iphidonopsis Gwiazdowicz, 2004 are reviewed, and a new combination, Iphidonopsis magnanalis (Ma & Yin, 1999) comb. n., is presented for Iphidozercon magnanalis Ma & Yin, 1999 from China. The genus Diseius Lindquist & Evans, 1965 is provisionally moved from the family Ascidae to the Digamasellidae. A new key to the genera of Arctoseiinae is presented.
