Tarsonemus

Adult Tarsonemus can be recognised by (among other features) simple unmodified setae on the dorsal idiosoma, two pairs of setae on the metapodosomal venter, short cheliceral stylets, and a gnathosomal capsule that is not conspicuously beaklike.{{Cite web |title=Tarsonemus {{!}} Bee Mite ID |url=http://idtools.org/id/mites/beemites/factsheet.php?name=15293 |access-date=2022-08-25 |website=idtools.org}}

Females of Tarsonemus have a pair of clubbed trichobothria on the prodorsum, ambulacrum I developed, the tegula short and rounded, the fourth leg pair clearly longer than the tegula, and the segugal apodeme developed.

Tarsonemus mites live in various habitats including soil, litter, both woody and herbaceous plants, decaying wood, underneath bark (where they are associated with insects), animal nests, bracket fungi, stored foods, laboratory cultures and house dust. They are mostly fungivores and some are economically important pests of commercial mushroom cultures and laboratory fungal cultures. They can sometimes carry fungal spores on their bodies. A few Tarsonemus species are herbivores (attacking crop or ornamental plants) or feed on exudates of living animals.

The genus overall has a cosmopolitan distribution. Additionally, the bee-associated species have been recorded from every zoogeographical region except Afrotropical.

There are over 280 Tarsonemus species described, grouped into the three subgenera of Tarsonemus sensu stricto, Chaetotarsonemus and Schaarschmidtia.{{Cite journal |last1=Sousa |first1=André Silva Guimarães |last2=Rezende |first2=José Marcos |last3=Lofego |first3=Antonio Carlos |last4=Ochoa |first4=Ronald |last5=Bauchan |first5=Gary |last6=Gulbronson |first6=Connor |last7=Oliveira |first7=Anibal Ramadan |date=2020-06-02 |title=Two new species of Tarsonemus (Acari: Tarsonemidae) from Bahia, Brazil |url=https://www.biotaxa.org/saa/article/view/saa.25.6.4 |journal=Systematic and Applied Acarology |volume=25 |issue=6 |pages=986–1012 |doi=10.11158/saa.25.6.4 |s2cid=219929651 |issn=1362-1971|doi-access=free }} Some of them are:
