The genus Lepidocyrtus consists of 18 recognized species in North America. Several attempts have been made to subdivide the genus into subgenera and groups based on different morphological characters. The North American species of Lepidocyrtus can be divided into two subgenera (sensu Yosii) or three groups (sensu Gisin). Morphology alone, however, has not been sufficient to resolve the relationships. I present the results of a cladistic analysis to test two hypotheses for the North American species of Lepidocyrtus based on morphology and mitochondrial sequence data (COI).
