Observations on the mites (Acari) associated with Carabidae (Coleoptera) in Belgium. I. Annotated list of the species

Abstract

The acarofauna associated with Carabidae (Coleoptera) in Belgium is studied. About 1000 mites were collected from 19 sites from 155 carabid beetles belonging to 21 species and 8 genera. The mites belonged to 12 species, 8 genera, 8 families and 3 orders. AlI mites were found beneath the elytra of the beetles except the hypopi of the Histiostomatidae which were found attached to the body. A new species ofAntennoseius, A. calathi n. sp. (Ascidae), is described from Calathus microptems and Pterostichus diligens. More than half of the mites of our collections were deutonymphs belonging to 2 species of the genus Halodarcia Karg (Halolaelapidae) Le. H. incideta Karg, 1969 and Halodarcia sp.
