The genus Aituaria Esyunin et Efimik, Recently, additional Aituaria specimens have been 1998 is redefined as monotypic. It is close to the pre- collected from the City of Perm (Russia). Having ex- dominantly Caucasian borutzkyi species group of the amined them, the author has come to the conclusion genus Carpathonesticus Lehtinen et Saaristo, 1980, that A. nataliae and A. pontica are to be considered but can easily be distinguished from it by the broad, conspecific. The main aims of this paper are (1) to ribbon-shaped embolus notched at its tip, as compared synonymize both species names, (2) to illustrate im- to the narrow, tapering off embolus in the borutzkyi portant diagnostic characteristics of the male palp, and species group. The species Aituaria nataliae Esyunin (3) to provide new distributional and ecological data et Efimik, 1998 is synonymized with A. pontica for A. pontica. (Spassky, 1932). A. pontica is reported from the Mid- dle Urals for the first time, its male palp is illustrated Material and methods and distributional and ecological data are also summa- rized. SEM micrographs were made by means of a Hita- chi TM3000 SEM microscope with BSE (back-scat- РЕЗЮМЕ.
