The bee family Halictidae (Hymenoptera, Apoidea) from Central Asia collected by the Kyushu and Shimane Universities Expeditions

Central Asia is one of the important centers of bee diversity in the Palearctic Region. However, there is insufficient information for many taxa in the central Asian bee fauna. The Kyushu and Shimane Universities (Japan) Expeditions to Kazakhstan, Kyrgyzstan, Uzbekistan, and Xinjiang Uyghur of China were conducted in the years 2000 to 2004 and 2012 to 2014. Eighty-eight species of the bee family Halictidae Thomson, 1869 are enumerated including new localities in central Asia. Halictus tibialis Walker, 1871, H. persephone Ebmer, 1976, Lasioglossum denislucum (Strand, 1909), L. griseolum (Morawitz, 1872), L. melanopus (Dalla Torre, 1896), L. nitidiusculum (Kirby, 1802), L. sexnotatulum (Nylander, 1852), L. subequestre (Blüthgen, 1931), L. sublaterale (Blüthgen, 1931), and L. zonulum (Smith, 1848) are recorded from central Asia for the first time. Thirty-two species are newly recorded from Kazakhstan, 19 spp. from Kyrgyzstan, 2 spp. from Uzbekistan, and 11 spp. from Xinjiang Uyghur of China. The genus Lasioglossum dominated the number of species and individuals in the collection. The halictid fauna mostly composed of western to central Asian elements in our surveyed area

Notes on the Nest Architecture of Halictus senilis (Eversmann) in Southeast Kazakhstan (Hymenoptera, Halictidae)

Four nests of Halictus senilis (Eversmann) were excavated near Chimkent, southeast Kazakhstan. The nest of H. senilis was similar in structure to nests of the other species of Halictus s. s., i.e., each cell directly, not by means of lateral, connected to the main burrow. On the other hand, the deviation from the typical nest structure of Halictus was found. The coexistence of delayed eusocial and solitary nests was suggested in this species

A New Species Belonging to the Subgenus Euandrena of the Genus Andrena from Xinjiang Uygur, China with Notes on Nest Structure (Hymenoptera, Andrenidae)

A new species belonging to the subgenus Eyandrena of the genus Andrena is described from Xinjiang Uygur, China. It is the species most associated with the semi-desert flowers of Chondrilla brevinotris (Compositae) in the Dzungaria Basin. The nest structure of the species is detailed
