[2 new species of mites in the genus Neotrombicula (Trombiculidae) from the western Caucasus].

Two new species of the genus Neotrombicula Hirst, 1925 are described from Western Caucasus. Neotrombicula alexandrae sp. n. is similar to N autumnalis (Shaw, 1790) but differs from it by several measurable characters and by sensillae barbed only in distal half. N. abagoensis sp. n. slightly resembles N. autumnalis and differs from it by significantly greater value of the majority of standard measurements, NDV and by more thick barbs of D. Specimens of new species were collected on rodents near the towns Maikop, Anapa, and in the area of the Caucasian reserve. All holotypes and paratypes of new species are deposited in the Zoological Institute, Russian Academy of Sciences (Saint-Petersburg).
