title: Larval morphology of Hydryphantes clypeatus Thor, 1899, H. dispar Schaub, 1888 and H. planus Thon, 1899 (Acari, Hydrachnidia: Hydryphantidae).
abstract: Larvae of the water mite species Hydryphantes clypeatus Thor, 1899 are described for the first time, and redescriptions of the larvae H. dispar (Schaub, 1888) and H. planus Thon, 1899 are presented. The present data suggest that H. clypeatus and H. hellichi Thor, 1899, two species recently considered as a junior synonyms of H. planus resp. H. ruber (Geer, 1787) should be recognized as separate species. Separate keys to all named species based on larvae and adults are given.
