Acanthophthirius kolenatii, a new species, and some new records of fur-mites (Acarina: Myobiidae and Labidocarpidae) from Armenia.

A description of the female of a new species, Acanthophthirius kolenatii sp.n., is given. The species is very closely related to A. poppei (Trouessart, 1895) and A. etheldredae Perkins, 1925 and has been collected from Pipistrellus kuhli (Kuhl) in the Armenian S.S.R. The species Pteracarus pipistrellius pipistrellius (Radford, 1938) and Alabidocarpus calcaratus calcaratus Lawrence, 1952 are recorded from the territory of Armenia for the first time.
