Eucera (Synhalonia) dubitata (Cresson 1878) (New state record)

County records: Cass.

Notes. This species could be easily mistaken for E. atriventris, which is relatively abundant in the southwestern part of the state. Females can be distinguished from E. atriventris by the paler hind tibial scopa and the highly polished integument of the mesoscutum. Timberlake (1969) recorded E. dubitata from both Carlinville, Illinois and Columbus, Ohio.
