Diagnosis. Atheta pennsylvanica   belongs to a group of distinctly colored species within Microdota   with dark brown head and abdominal terga 5–8, light brown elytra, and reddish yellow pronotum and abdominal terga 3–4. Atheta pennsylvanica   can be distinguished from other species of this group by having a larger body size and the distinct shape of the aedeagus ( Figs. 114–115 View FIGURES 112–115 ) and spermatheca ( Figs. 112–113 View FIGURES 112–115 ).

Discussion. The types of At. fontis   are similar to the types of At. pennsylvanica   in the body size, in external characters and in the shape of the spermatheca. Therefore, the synonymy of the two species established by Fenyes (1920) and Bernhauer & Scheerpeltz (1926) is confirmed. I agree with Bernhauer & Scheerpeltz (1926) that of all species of Microdota   described by Casey (1910a, 1911a) only At. fontis   is synonymous with At. pennsylvanica   .

Distribution. Atheta pennsylvanica   is widespread in the eastern United States (Vermont, Massachusetts, New York, Pennsylvania and Minnesota) and is also known from eastern Canada (Ontario, Québec).
