Type material of 3 North American Verrucoentomon (Protura: Acerentomidae, Nipponentominae) species was studied: Verrucoentomon imadatei Nosek, 1977 from Alaska, Verrucoentomon mixtum Nosek, 1981 from Alaska and Verrucoentomon canadensis (Tuxen, 1955) from northern Canada. Additional morphological characters for Verrucoentomon imadatei, Verrucoentomon canadensis are provided. Verrucoentomon mixtum is redescribed and transferred to the genus Imadateiella Rusek, 1974 due to the presence of 4 pairs of A-setae on the metanotum rather than 3 and the absence of teeth on the hind margins of segments IX-XI. Imadateiella mixta (Nosek, 1981) is characterized by the presence of P1a setae on tergites I-VII, 4 A-setae on tergite VIII and only 4 setae on sternite VIII. The species is unique within the Nipponentominae in having only one long terminal spine on the labial palp. Imadateiella is redefined and a key to its species is provided.
