Andrena (Cnemidandrena) peckhami Cockerell 1902 ( chromotricha group) (New state record)

( Fig. 5B )

County records: Iron.

Notes. The type female (NMNH) of A. peckhami was described in the same publication as A. parnassiae , and was also collected in Milwaukee, Wisconsin, but on 24 July (likely 1901). This species resembles A. parnassiae but can be recognized by the smoother more sparsely punctate medial area of the clypeus and convergent eyes above. It should be noted that the convergent eyes of A. peckhami and A. chromotricha (above) is subtle and requires careful examination. A single female was compared to a Minnesota specimen determined by Mitchell (MSUC) and images of the type (NMNH).
