ABSTRACT: The first description of deutonymph and redescription of larva, female and male of the water mite Hydryphantes nonundulatus Viets, 1919 are given. I reject previous proposals (Lundblad,1962) and Di Sabatino et al., 2009) to synonymize H. nonundulatus with H. planus Thon, 1899.
KEY WORDS: water mite, Hydryphantidae, Hydryphantes nonundulatus, morphology, larva, deutonymph, female, male.
