Morphology of some species of Limnozetes Hull, 1916 (Acari: Oribatida: Limnozetidae), and keys to the larvae and nymphs

All juvenile stages of Limnozetes ciliatus (Schrank, 1803) and deuto- and tritonymph of L. palmeme Behan-Pelletier, 1989 are redescribed and illustrated, and the larva and protonymph of L. palmerae are described and illustrated for the first time. Both species are similar with respect to the body shape, but differ mainly in the shape of some setae in the juveniles, presence of aggenital setae, formula of genital setae, and sculpture of cerotegument in the adult. Relations of species within Limnozetes Hull, 1916 are discussed, and keys to the larvae and nymphs of four European species of this genus are provided.
