Biology:Trogiomorpha

From HandWiki

Trogiomorpha is one of the three major suborders of barklice, booklice, and parasitic lice in the order Psocodea (formerly Psocoptera),[1][2] alongside Troctomorpha and Psocomorpha. There are about eight families and more than 430 described species in Trogiomorpha.[3][4][5] Trogiomorpha is widely agreed to be the earliest diverging of the three suborders, and retains the most primitive characteristics.[6]

Characteristics

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]

Classification

Trogiomorpha contains three infraorders and five extant (living) families, as well as three identified extinct families:
