Three females of Auplopus carbonarius, a Palearctic species detected recently in southeastern New York, were collected in a Malaise trap in Ann Arbor, Michigan, during the summer of 1988. Females of the species can be separated morphologically from those of the similar A. variolarum by the polished and essentially impunctate pygidium, dusky wings, and median clypeal tooth.
