Material (show database records).

General Description. This family is distributed worldwide and includes 426 species and 35 genera grouped in 2 subfamiles: Parasitinae and Pergamasinae (Beaulieu at al., 2011; Johnston, 1982; Tichomirov, 1977). Parasitid mites are essentially predatory and feed upon other microarthropods, including their eggs, and on nematodes. They live in moss, forest litter, soil, dung, rotting seaweed, decaying organic substances, caves, and nests of small mammals and insects. These mites disperse during the deutonymph stage, usually on insects of the orders Coleoptera and Hymenoptera. All species of the genus Parasitellus are obligatory associates of bumblebees (Bombus) in the Holarctic region. Several occasional records of different species of the genus Parasitus and Vulgarogamasus are known from bumblebee nests and honeybee hives in North America and Europe. Pergamasus crassipes (Linnaeus, 1758), Pergamasus diversus Halbert, 1915, Poecilochirus necrophori Vitzthum, 1930, Holoparasitus sp., and Eugamasus sp., were recorded from the honeybee, Apis mellifera L. in Europe and Iran (Chmielewski W. 1991; De Jong et al., 1982; Haragsim et al., 1987; Grobov, 1975, 1978; Kamali at al., 2001; Mosaddegh, 1997), but these records probably are also accidental.
