Comments. This is the sole record for this widespread species from Michigan, based on a determination by Dr. William Ricker in 1965. There are, however, several series of collections from northern Michigan ( Alger, Keweenaw, and Otsego Cos.) with only females that may be of this species or A. varshava (Ricker) . The females of the two species are similar and difficult to separate, and males are needed for verification. We expect A. varshava to be present in Michigan, especially since the type locality is in northern Indiana ca. 60 km south of the Michigan border. We have recent material of A. varshava from both northeastern Wisconsin and northern Indiana.
