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

Abstract Background 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. New information 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.

A total of 12 species are recognized for the country. Lasioglossum circularum Fan & Ebmer is recorded for the first time from the Korean Peninsula and the following species are newly recorded from South Korea: L. denticolle (Morawitz), L. formosae (Strand), L. kansuense (Blüthgen), L. occidens (Smith), L. sutshanicum Pesenko, and L. upinense (Morawitz). Bionomical data as well as illustrated keys to females and males of South Korean species are provided. DNA sequences including a part of barcode region are given for L. kansuense and L. occidens.

Seladonia (Pachyceble) henanensis sp. n. (Hymenoptera, Halictidae) from China.

Abstract Seladonia (Pachyceble) henanensis sp. n., is described from Henan Province, the eastern-central part of China.
