Halictus hedini Blüthgen, 1934: 5.
DIAGNOSIS: Halictus hedini hedini is morphologically similar to its consubgener H. rubicundus. It is separated from H. rubicundus by the male flagellum ventrally with a fringe of short hairs 0.3–0.5× as long as flagellomere diameter and first metasomal tergum with coarse and deep punctures in both sexes (Fig. 3). In contrast, H. rubicundus has the male flagellum ventrally without a distinct fringe and the first metasomal tergum with fine and shallow punctures in both sexes (Fig. 4) (Pesenko, 2005). The dark legs of the female separate H. hedini hedini from the subspecies H. hedini hebeiensis Pesenko & Wu, 1997, which was described from China.

DNA BARCODE (Table 1): Most publicly available COI sequence data for H. rubicundus comes from other primer sets that overlap only partially with the DNA barcode fragment (Soucy & Danforth, 2002). Our results show a 2.9% genetic distance over 429 bp shared with H. rubicundus sequences. A single downstream sequence of 863 bp was compared to 39 published H. rubicundus COI sequences and was found to have a minimum of 3.0% genetic distance, consistent with the DNA barcode fragment.
DISTRIBUTION: Eastern to Central Asia: Japan (Hokkaido and northern to central Honshu), China, Mongolia, Russian Far East, Siberia, Kazakhstan (Pesenko, 2005).
