title: Track analysis of Oribatid mites (Acari: Oribatida) of the Subantarctic subregion of South America.
abstract: We analysed distributional data of 30 species of Oribatid mites of the Subantarctic subregion of southern South America in order to contribute to elucidate their biotic evolution. We constructed individual tracks for the species analysed, based on published and unpublished records. After superposing them we obtained six generalized tracks and five nodes. Four generalized tracks (T2, T3, T4 and T6) extend along and near the Andean ranges, whereas two generalized tracks (T1 and T5) may be artefacts caused by the lack of information. The generalized tracks and nodes show the complex relationships of the austral biota, as hypothesized in previous contributions based on other plant and animal taxa.
