First detailed records of water mite larvae (Hydrachnidia: Hydrovolzidae, Hydryphantidae) parasitizing empidid flies (Diptera: Empididae: Clinocerinae).

Five species of the subfamily Clinocerinae from the Tatra Mountains (S Poland) were observed to be parasitized by larval water mites. Two of them: Mik, 1880 and Mik, 1880 are recorded from this massif for the first time. In addition, is new for Polish fauna. The most infected species was Zetterstedt, 1838, following by (Bezzi, 1899), Mik, 1880, Mik, 1880 and Niesiołowski, 1987. The highest number of hosts occurred in the case of (Walter, 1907) with five host species, following by both (Monti, 1905) and (Protz, 1896) with one species each. In the case of more parasites were recorded on males than on females and in more parasites were recorded on females. The abdomen of the hosts was the most often chosen by water mites larvae.
