A Revision of the Genus Typhlodromus Scheuten

The genus Typhlodromus Scheuten is here revised and keyed to species. Two new subgenera, Trionus and Oudemanus are herein described and 27 species are illustrated, including 3 new species: Typhlodromus knisleyi, Typhlodromus quercicolus, and Typhlodromus zaheri. The following new synonomies are proposed: Typhlodromus perbibus Wainstein and Arutunjan as a junior synonym of Typhlodromus athiasae Porath and Swirski; Typhlodromus exhilaratus Ragusa as a junior synonym of Typhlodromus tiliae Oudemans; and Typhlo­ dromus eucervix Karg and Edland as a junior synonym of Typhlodromus andrei Karg. The plant hosts, food hosts, and distributions are discussed.
