Adult male Sphaerotarsus allmani, from Southcott (1961).

Belongs within: Parasitengonina.
Contains: Erythraeinae, Balaustiinae, Callidosomatinae, Leptus, Smaridinae.

The Erythraeoidea are a group of mites in which the adults and nymphs are predatory. The larvae are generally parasitic on other arthropods, though a few species are known to feed on pollen. Living erythraeoids are divided between the two families Smarididae and Erythraeidae. Adults of the Smarididae generally have flattened bodies, and the gnathosoma is placed on an extendable collar that can be fully retracted into the idiosoma. The Erythraeidae are generally less flattened, and the gnathosoma is not fully retractable. Two pairs of eyes are present in the smaridid taxa Smaridinae and Phanolophus and the erythraeid Erythraeinae. Phanolophus has the eyes placed between the levels of the anterior and posterior sensillary areas on the crista. A single pair of eyes is present in the smaridid Hirstistomatinae and the other erythraeid subfamilies (Southcott 1961). A third family has been recognised for Proterythraeus southcotti, described from a larva found in Cretaceous Canadian amber.

Characters (from Southcott 1961): Eyes always present, sessile, one or two on each side. Thumb-complex present to palp. Two pairs of idiosomal sensillae (bothrialae) present: in the adult these are usually placed on a dorsal crista metopica; in the larva usually placed on a dorsal scutum. Chelicerae of adult styliform. Adult peritremes placed dorsally on mouth-cone, longitudinal. Larvae without external genital aperture or anus. Larval coxae always separated. Larva without urstigma.
