A review of oribatid mites of the family Liacaridae (Acariformes,Oribatida) from the Caucasus

The paper summarizes the data on oribatid mites of the family Liacaridae and their distribution in the Caucasus. Two new species, Liacarus subiasi from Azerbaijan (differing from the known species in the shape of cuspids and short lamellae) and Dorycranosus musaevi from Daghestan (differing from closely related D. splendens (Coggi, 1898) and D. punctulatus Miheli?i?, 1956 in the presence of the smooth notogaster, wide distal lamellar cuspids, and also in the absence of inner cuspid tooth and the presence of longer ventral setae), are described. The species status of D. punctulatus is reestablished. Liacarus lencoranicus Krivolutsky, 1967 and L. nitidulus Krivolutsky, 1967 are synonymized with L. coracinus C.L. Koch, 1898. D. zachvatkini Kuliev, 1962 (= D. ibericus Dzaparidze, 1973) is redescribed. Data on species variability of Adoristes poppei (Oudemans, 1906) and A. ovatus Koch, 1849 are given.
