The following notes are based on the material in the Canadian National Collection and in the collections of the United States National Museum, the Museum of Comparative Zoology, and the Philadelphia Academy of Natural Sciences.In all of the three American species of Lyperopherus, the flattened side margins of the pronotum are gradually widened posteriorly to include the outer of the basal impressions. All are flightless and have the elytra widest slightly behind the middle.
