Discussion. The types of Dat. decolorata, Dat. inopia, Dat. schematica and Dat. stilla do not differ from examined European specimens of At. dadopora .

Distribution. Atheta dadopora is a common European species. In North America At. dadopora is known from Rhode Island, New York, Pennsylvania and Newfoundland. This is the first record of this species from North America.
