The phylogenetic relationships of bark lice and parasitic lice ( I nsecta: P socodea) have been studied in a number of recent molecular phylogenetic analyses based on DNA sequences. Many of these studies have focused on the position of parasitic lice within the free‐living bark lice. However, fewer such studies have examined the relationships among major groups of free‐living bark lice and their implications for classification. In this study we focus on the infraorder C aeciliusetae, a large group of bark lice (˜1000 species) within the suborder P socomorpha. Using sequences of two mitochondrial and two nuclear genes, we estimated the phylogeny for relationships among the five recognized families within the infraorder C aeciliusetae. Based on the results, the sister‐group relationship and respective monophyly of S tenopsocidae and D asydemellidae is strongly supported. Monophyly of the larger families A mphipsocidae and C aeciliusidae was not supported, although the causes of this were the placement of two distinct subfamilies ( P aracaeciliinae and C alocaeciliinae). The monophyly of A siopsocidae could not be tested because it was sampled only by one species. Based on these results and consideration of morphological characters, we propose a new classification for C aeciliusetae, recognizing six families: A mphipsocidae, S tenopsocidae, D asydemellidae, A siopsocidae, P aracaeciliidae and C aeciliusidae. We expect that this new classification will stabilize the higher‐level taxonomy of this group and help to identify groups in need of further work among these insects.
