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 8 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]

Species of Trogiomorpha possess antennae that are split into 20 or more separate pieces. [8] The tarsi are segmented into three separate equal pieces, and they have a strong posterior spine. They have been described as having a "mothlike" (brown) appearance in color. [8]
Trogiomorpha contains 3 infraorders and 5 extant (living) families, as well as three identified extinct families:
