Osmia (Hoplosmia) tyrneri ( Tkalců 1992)

Hoplosmia (Hoplosmia) tyrneri Tkalců 1992: 220 . Type material: Holotype ♂, “ Tashkent , Galvasai, 25.6.1980 ” ( Uzbekistan), Oberösterreichisches Landesmuseum Linz.

Literature records. UZBEKISTAN: Chatkal Mountains, 70 km NE Tashkent/Galvasai ( Tkalců 1992).

Distribution. Known only from the sourroundings of Tashkent in eastern Uzbekistan.

Nesting biology. Unknown.

Pollen hosts. Unknown.

Notes. Female unknown. B. Tkalců erroneously labelled the specimen that was designated as holotype in his original publication as a paratype, which is deposited in the Oberösterreichische Landesmuseum Linz. Thus, Linz is actually the holotype depository of O. tyrneri and not the Tyrner Collection in Litvinov as stated in Tkalců (1992). The males of O. tyrneri and O. spinulosa differ only slightly, e.g. in the shape of the sternal spine, the punctation of the integument and the colour of the body pilosity (see Key to species), suggesting conspecificity. However, these separating characters do not seem to clinally change from west to east, since males of O. spinulosa from both northern Kyrgyzstan and southeastern Kazakhstan are morphologically almost identical to those from Europe. Therefore, O. tyrneri is regarded here as a species of its own in spite of its very close resemblance to O. spinulosa .
