Osmia laticeps THOMSON 1872; Osmia svenssoni TKALCŮ 1983
Several years ago, D B Baker and G R Else found that the series of Scottish Osmia inermis in the Natural History Museum, London, consisted of two closely related species: O. inermis and O. uncinata. The latter was a species not previously known from the British Isles.
Osmia uncinata, in common with O. inermis, is confined to the Highlands of Scotland, but it seems to be less localised, with records from Highland Region: Speyside (Kincraig to Nethy Bridge), Ardersier and Bonar Bridge (Else & Edwards, 1996). It is occasionally locally numerous. Other sites worth investigating for the presence of this species are Deeside (Grampian Region) and Glen Affric (Highland Region).
