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