Key to adult female Tenuipalpidae from Casuarinaceae
This key is based partially on that of Mesa et al. (2009). Tenuipalpus and Brevipalpus are included because these common genera are likely to be encountered occasionally from samples, and Ultratenuipalpus is included because we have collected several undescribed species from Casuarinaceae (unpublished data). This genus will be subjected to a future revision encompassing species on numerous host plants.
