The spruce cone moth, identified as Dioryctria reniculella (Grote) by Heinrich and other authors, is described as D. reniculelloides n. sp. This and D. pseudotsugella Munroe form a compact group closely related to the European D. schuetzeella Fuchs. These three species are characterized. D. reniculella is sunk as a junior synonym of D. abietivorella (Grote), new synonymy.
