Trogiomorpha is one of the three major suborders of barklice, booklice, and parasitic lice in the order Psocodea (formerly Psocoptera),[2][3] alongside Troctomorpha and Psocomorpha. There are about eight families and more than 430 described species in Trogiomorpha.[4][5][6] Trogiomorpha is widely agreed to be the earliest diverging of the three suborders, and retains the most primitive characteristics.[7]
