Epipsocidae is an insect family of Psocodea (formerly Psocoptera) belonging to the suborder Psocomorpha,[1] that includes, among others, the genera Bertkauia, Epipsocus, Epipsocopsis, Goja, and the New Guinean endemic Dicropsocus. It includes 16 genera with more than 140 species.[2] The only European species in the family is the (almost always) apterous Bertkauia lucifuga. Like the other members of the infraorder Epipsocetae, they have a labrum with two sclerotized ridges. Epipsocids are barklice found primarily in tropical regions, and one of their distinguishing characteristics is the hairy ventral surface of the forewing.[3]
