Lasioglossum (Dialictus) rozeni Gibbs, 2011

Comments. Gibbs (2010) incorrectly referred to this species as L. cephalotes (Dalla Torre, 1896) . The correct usage of L. cephalotes was subsequently determined, and L. rozeni was described as new ( Gibbs 2011). Lasioglossum rozeni has not yet been recorded from Canada, but it is known from adjacent states. It is included in the key because its distribution suggests that it may occur in southern Ontario. It frequently co-occurs with L. versatum (Robertson, 1902) . The relatively large size of both species suggests a possible host–parasite association.
