Based on a study of more than 31,000 Staphylinidae recently collected in various habitats and using differ- ent methods, and on a critical evaluation of previous literature records, a checklist of the faunas of Armenia and Nagorno-Karabakh is compiled. The fauna of Armenia currently includes 675, that of Nagorno-Karabakh 198 named species. Nevertheless, it is concluded that the species inventory of both regions, especially that of Nagorno-Karabakh, is still far from complete. As many as 262 and 183 species are reported from Armenia and Nagorno-Karabakh, respec- tively, for the first time. A list of 99 species erroneously or doubtfully recorded from the study region is provided. A comparison with the species number and systematic composition of the faunas of other Caucasian countries and regions revealed that (a) their known diversities are significantly lower than should be expected and (b) a remark- ably high proportion (nearly 40 %) of Aleocharinae in the faunas of Armenia and Nagorno-Karabakh, with the genus Atheta T"#&'#*, 1858 alone accounting for approximately 10 % of the total diversity in Armenia.
