The microsporidium Intexta acarivora gen.
Reproduction is restricted to the production of sporoblasts.
Sporogony is by vacuolation, and mature spores are spherical to slightly ovoid and lack a polaroplast. The external zone of the polar filament contains tubular material, and the polar sac is without an anchoring disc. The species is compared to previously described microsporidia of mites, and the genus and family affiliations are discussed.
