Classification

There is general agreement that there are five main lineages in suborder Oniscidea, although the phylogenetic relationships between them are unsettled. Two main schemes for the classification that differ in which group is considered sister to the remaining oniscideans. One places Ligiidae in section Diplocheta, with the remaining families divided between four sections in infraorder Holoverticata. The other places Tylidae in infraorder Tylomorpha, with the remaining families placed in three sections in infraorder Ligiamorpha. The former scheme is presented below.
