Comments

This unknown species has been identified as Lasioglossum (Hemihalictus) sexstrigatus (Schenck, 1869) in Japan. According to DNA analysis in the present study, the pair-wise sequence divergence between Japanese and European specimens was quite clear (7.3–7.9% between L. sexstrigatus and L. sp. in Table 1 View Table 1 ). Morphologically, females of this species are slightly different from L. (H.) sexstrigatus as the mesoscutum has a weak tessellation over the entire surface (in contrast, in L. (H.) sexstrigatus , the mesoscutum is nearly smooth on the posterior half).

In the present study, I could not conclude that this unknown species is either undescribed or a known species, but this will be examined in further studies.
