A new species, Anthrenus canadalunai is described and imaged. The new species is compared with two cofounding species: A. angustefasciatus Ganglbauer, 1904 and A. mroczkowskii Kalik, 1954. Images of the habiti, antennae, aedeagi, and sternite IX are presented. The new species is separated from A. angustefasciatus and A. mroczkowskii based on aedeagal and sternite IX structure. Following on from this, external features, such as colour pattern, are identified facilitating identification. The distributions of all three species are presented and discussed.
