The Limnesiidae are a diverse group of water mites of questionable monophyly. Larvae, where known, are parasites of culicomorph Diptera. The limnesiids are divided between several subfamilies of diverse appearance. One possibly monophyletic assemblage, including the Neomamersinae, Psammolimnesia, Nicalimnesia, Stygolimnesia, Protolimnesiinae and Mixolimnesia, includes small, elongate and well-sclerotised taxa. Conversely, Kawamuracarus is a genus of large, soft-bodied species found in interstitial habitats in the Holarctic region (Walter et al. 2009). The cosmopolitan Limnesiinae have a globular to egg-shaped idiosoma with ring-like genital flaps in males formed from fusion of the anterior and posterior margins.

Characters (from Walter et al. 2009): Adults with palpfemur, with extremely rare exceptions, bearing ventral seta; all females, and males of many genera, with genital acetabula borne on movable genital flaps. Larvae with cheliceral bases fused; two pairs of urstigmata borne distally between coxal plates I-II; legs with five movable segments; tibiae I-II bearing seven to eight setae (and two solenidia), including only three ventral setae, lacking either Ti8 and Ti9 or Ti10 and Ti11.
