Diamesa davisi Edwards

Diamesa davisi Edwards, 1933: 614; Goetghebuer 1939: Hansen & Cook 1976: 81; Willassen 1986: 112; Ashe & O’Connor 2009: 274.

Remarks. We do not have additional material to study morphology and to perform DNA barcoding of this species, so we accept Willassen (1986) conclusions.

Distribution. Nearctic species, known from Canada, Greenland and U.S.A. (Ashe & O’Connor 2009).
