Abstract
Homologies of the glandularia in the water mites (Acari: Prostigmata: Parasitengona: Hydrachnidia) are discussed. The fundamental 18 pairs of glandularia (sensu Bader, 1982) were never found, epimeroglandularia E1 and E3 being universally absent. E4 was shown to be highly variable in position. Homologies of glandularia are suggested for some major water mite taxa.
