Contributions to the halictid fauna of the Eastern Palaearctic Region: genus Lasioglossum Curtis (Hymenoptera: Halictidae, Halictinae)

Yu.A. Pesenko

Abstract. The paper presents results of the taxonomic study of the bees of the genus Lasioglossum from the Eastern Palaearctic Region. A new subgenus, Lasioglossum subg. Warnckenia subg. n., and hitherto unknown males of L. circularum Fan & Ebmer, L. ochreohirtum (Blüthgen), and L. zeyanense Pesenko are described. New synonymies are established: Halictus subg. Leuchalictus Warncke, 1975 = Lasioglossum subg. Sericohalictus Pesenko, 1986, syn. n. = Lasioglossum subg. Bluethgenia Pesenko, 1986, syn. n.; L. agelastum Fan & Ebmer, 1992 = L. nipponicola Sakagami & Tadauchi, 1995, syn. n.; L. eos Ebmer, 1978 = L. kasparyani Pesenko, 1986, syn. n.; L. leucozonium (Schrank, 1781) = Halictus satschauensis Blüthgen, 1934, syn. n., = L. satschauense mandschuricum Ebmer, 1978, syn. n.; L. occidens (Smith, 1873) = L. koreanum Ebmer, 1978, syn. n.; L. iungusicum Ebmer, 1978 = Halictus tinnunculus Warncke, 1982, syn. n. The lectotypes of Halictus carbonarius Blüthgen (=L. upinense), H. chlapovskii Vachal (=L. rostratum), H. laevifrons Blüthgen (=L. denticolle), and H. soreli Dours (=L. xanthopus) are designated. L. formosae (Strand), L tungusicum (Ebmer), and L. xanthopus (Kirby) are recorded for the first time from continental China, L. formosae and L. subopacum (Smith), from Vietnam, L. chloropus (Morawitz), from Russia (Irkutsk Prov.). A total of 38 species of the genus Lasioglossum were found in the Eastern Palaearctic Region. A key to all of them is given. An annotated list of species includes data for each species on its synonymy, general geographical distribution, published records from the Eastern Palaearctic Region, and the material examined.
