a shield that covers all of the dorsum. In Mesostigmata, the holodorsal shield is often interpreted as resulting from the fusion of podonotal and opisthonotal shields and a suture between these regions is often visible (see recurved and procurved).

About 40 species of Antennoseius are known from soil and litter habitats (especially from moist soils), mammal nests, and phoretic on ground beetles. Most belong to the subgenus (Antennoseius), but at least 2 of the 10 known species of the subgenus Antennoseius (Vitzthumia) produce a phoretic morph with generally smooth cuticle and have a free-living morph with highly ornate cuticle. The few species that have been studied feed on nematodes, mites and small insects.
