چکیده
Association with arthropods, most frequently insects, is typical phenomenon that has been evolved in many lineages of mites including mites of the cohort Heterostigmata (Acari: Trombidiformes: Prostigmata). One of the largest superfamilies in Heterostigmata is Pygmephoroidea with four families Pygmephoridae, Neopygmephoridae, Scutacaridae and Microdispidae. Mites of the family Microdispidae are the least diverse and the least studied mites in the suprfamily Pygmephoroidea composed of 25 genera and more than 120 species. Most microdispid mites are fungivorous living in soil however, sometimes are associated with various arthropods, especially insects, and utilize them for phoresy. During a survey on mite fauna associated with insects in some parts of northeastern Iran in 2015-2016, a sampling was performed around Behshahr city (Mazandaran province, Northern Iran) and Paramicrodispus crenulatus (Savulkina, 1978) (Acari: Microdispidae) was obtained on the Parandra caspia Ménétriés, 1832 (Coleoptera: Cerambycidae). The mite P. crenulatus could be recognized by all dorsal setae indistinctly barbed; setae d and f blunt-ended, other dorsal setae pointed; setae 1a and 2a with several large barbs, setae 1b, 2b, 3a, 3b, and 3c indistinctly barbed, other ventral setae smooth; setae ps2 vestigial. Previous records of P. crenulatus are from Bulgaria in the nest of a small mammal, from Crimea beneath elytra of a carabid beetle, Pterostichus niger (Schaller, 1783), and in a rotten log of Fagus orientalis, and from Golestan province (Norhtern Iran) associated with Lucanus ibericus Motschulsky (Coleoptera: Lucanidae). Therefore, this is the first report of the relationship between mites of family Microdispidae and beetles of the family Cerambycidae.
