A critical historical review of previous classifications and other work on tarsonemid and related mites is presented. General information concerning tarsonemids is reviewed, including the following: geographical distribution, life history, sex determination, sex ratio, copulation, adult female reproductive capacity and longevity, dispersal, food and host preferences, economic importance, and natural enemies.
The generic and suprageneric taxa of Tarsonemidae, as known from the world fauna, are revised systematically and phylogenetically, based on a comprehensive assessment of morphology, ontogeny, and homology of tarsonemid structures, including their condition as found in other families of Heterostigmata. The fundamental systems of setal notation developed by Grandjean for the body and appendages of acariform mites are applied, including use for the first time of his special terminology for tarsal setae among heterostigmatic mites.
