Abstract: ABSTRACT: In Wisconsin, only one published species record exists for the omaliine rove beetle genus Eusphalerum. Two card-mounted specimens of Eusphalerum pothos were located in the research collection at the University of Wisconsin-Madison. The collection event label provided no date but the Bayfield, Wisconsin location is consistent with an 1895 species list provided by Wickham. New state records are confirmed for two species: Eusphalerum carolinensis and Eusphalerum convexum. A single specimen of E. carolinensis was collected on Rubus sp. in Dane County on 27 May 2017, while a series of 10 E. convexum came from Prunus spp. in Monroe County between 30 May and 4 June 1997.
