June 30, 2006 Contributions to the Halictid Fauna of the Eastern Palaearctic Region: Genus Seladonia Robertson (Hymenoptera: Halictidae, Halictinae) Yuri A. PESENKO Zoological Institute, Russian Academy of Sciences, 199034 St. Petersburg, Russia Abstract. This paper presents the results of a taxonomic study of the bees of the genus Seladonia from the Eastern Palaearctic Region. Two new species, S. leleji sp. n. and S. nikolskayae sp. n. from the Primorskii Territory of Russia, are described. A new synonymy is established: S. tumulorum fer- ripennis (Cockerell, 1929) = S. tumulorum higashi (Sakagami et Ebmer, 1979), syn. n. The taxonomic rank of S. gobiensis (Ebmer, 1982), originally described as a subspecies of S. pseudovestita (Blüthgen, 1925), is raised to specific status. The lectotypes ofHalictus semitectus Morawitz, 1874; H. mongolicus Morawitz, 1880; H. confluens Morawitz, 1890 [= S. aeraria (Smith, 1873)] and H. pjalmensis gasc- hunicus Blüthgen, 1935 are designated. Seven species, S. aeraria (Smith), S. argilos (Ebmer), S. go- biensis (Ebmer), S. indefinita (Blüthgen), S. petraea (Blüthgen), S. pjalmensis (Strand) and S. placidula (Blüthgen), are recorded from Mongolia for the first time. A total of 24 species of the genus Seladonia were found in the Eastern Palaearctic Region. A key to all species is given, except for the female of S. opacoviridis (Ebmer, 2005). An annotated list of the species includes data for each species on its syn- onymy, general geographical distribution, published records from the Eastern Palaearctic Region, and the material examined. Key words: Halictidae, Seladonia, Eastern Palaearctic Region, taxonomy, key, distribution.
