Osmia oramara and Osmia livida
In two samples of bees collected at the same locality and date in Turkey and Iran, respectively, females of Osmia (Pyrosmia) oramara Warncke, 1992 were found together with several males that exactly correspond to the description of the male of Osmia (Helicosmia) livida by Tkalcu (1978). As in both samples no females of O. livida were found, the male of O. livida as described by Tkalcu (1978) might be the still unknown male of O. oramara. If further material should support this assumption, then i) O. oramara would be a member of the subgenus Helicosmia rather than of the subgenus Pyrosmia, and ii) the male of O. livida would be still unknown.
