''Schwiebea'' is a genus of mites in the family Acaridae. It is among the largest in the family with over 60 species.

Description

Adults of ''Schwiebea'' are distinguished from other mites by: the absence of many setae, the reduction of supracoxal seta of leg I to a tiny spine, and the absence of Grandjean's organ. Additionally, the propodosomal sclerite has a posterior indentation/incision for up to 50% of its length. Females have a spermatheca (organ for receiving and storing sperm) and its morphology is important for distinguishing species.

Habitat

''Schwiebea'' have been collected from various habitats including vegetation ( clover roots, a verbena field, peony rose, '' Gerbera'' roots, yams, taro seeds), leaf litter, peat moss, caves, insect rearing containers and even some aquatic environments ( fish farms, aquariums, swimming pools). Some species attach phoretically to arthropods such as bark beetles, millipedes and ticks.

Reproduction

Some species of ''Schwiebea'' are all-female and reproduce by parthenogenesis, while others use sexual reproduction. Parthenogenesis is thought to have evolved at least three times within the genus.
