New species of Hypoaspis Canestrini and Coleolaelaps Berlese (Mesostigmata: Laelapidae) associated with Polyphylla olivieri Castelnau (Coleoptera: Scarabaeidae) in Iran 

Abstract

White grubs, including Polyphylla olivieri Castelnau, are among the most economically important pests of orchard trees and other crops such as potato and sugar beet. The larvae feed on the roots of the host plants and their adults feed on the leaves. Several types of organisms are parasitic or phoretic on this pest, including three species of mites from Iran. Two new species of mites, namely Hypoaspis (Hypoaspis) surii n. sp. and Coleolaelaps massoumii n. sp. are described here from the adults of P. olivieri in Hamedan, Iran. Hypoaspis polyphyllae Khanjani & Ueckermann was previously described from the larva of this species of beetle.
