A revision of the genus Lepidocyrtus: I. the pallidus group

The family Entomobryidae includes the genus Lepidocyrtus, one of the three largest genera of Collembola. Previous studies to determine the relationships between the species of this genus have either not been phylogenetic in nature or based exclusively on morphology. But morphology alone has not been sufficient to resolve the relationships between species due to large amounts of homoplasy. Gisin divided the Lepidocyrtus into three groups based on the chaetotaxy of the labium and the distribution of scales on the antennae and legs. I present the results of a phylogenetic analysis of the pallidus group, based on morphology and mitochondrial sequence data (COI), generated from taxa representing all members of the pallidus group, and representatives of the curvicollis and cyaneus group, to test the monophyly of the pallidus group.
