A world review of the ecclesiasticus species group in the genus Typhlodromus Scheuten (Acarina: Phytoseiidae)

Abstract
A new ecclesiasticus species group in the genus Typhlodromus Scheuten is proposed. The group is characterized primarily by the presence of seta z6 on the podoscutum and setae S2, S4, and S5 on the opisthoscutum. It is composed of 17 species: T. sentus Pritchard and Baker, T. neosentus van der Merwe, T. acanthus van der Merwe, T. sennarensis El Badry, T. parva (Matthysse and Denmark) comb, nov., T. kuzini (Wainstein), T. relenta (Matthysse and Denmark) comb, nov., T. ecclesiasticus De Leon, T. scytinus Chazeau, T. prunusus van der Merwe, T. yokogawae Ehara and Hamaoka, T. operantis (Chaudhri) comb, nov.,T. loricatus (Wainstein) comb, nov., T. bregetovae (Wainstein and Beglyarov) comb, nov., T. neosoleiger Gupta, T. ignavus (Chaudhri) comb, nov., and T. niloticus El Badry. Typhlodromus vitreus (Chaudhri) comb. nov. is designated as a junior synonym of T. bregetovae. Two species, T. ignavus and T. niloticus, are designated as "species inquirendae" because of insufficient information on their characteristics. Various generic concepts relating to the species in this group are reviewed. The group is described and a key to adult females and descriptions of each species are provided.
