NEW DATA ON TWO GAMASID MITES (ACARI: MESOSTIGMATA) FROM RUSSIA

Abstract

We present the first record of Longoseius (Longoseius) longus (Mesostigmata: Digamasellidae) from Russia. It was collected on a longhorn beetle Stictoleptura variicornis (Dalman) (Coleoptera: Cerambycidae). In addition, a detailed redescription of the female Leioseius mirabilis Nikolsky, 1981 (Mesostigmata: Ascidae) is provided. This species, known only from the type series, was found in coniferous-deciduous forest litter in eastern Russia (Primorye Territory). Our work also presents the first description of the male Leioseius mirabilis.
