Abstract

The larvae of water mites of the genusHydrachnaparasitise water bugs and water beetles. Larvae of the genusHydrachnaattach to the thorax and abdomen sternites and tergites under the elytra. Up to now six species ofHydrachnawere recorded from Iran, but there are no records on larvae parasitising on water beetles. There is some information about parasitising ofHydrachnaon water beetles from the genusEretes, which is very well adapted to dry climate. The aim of this paper is to describe the morphology of an unknown larva of the genusHydrachna, found onEretesgriseus.
