The Psocinae is a diverse group of barklice, some of which are particularly large for that order. Historically, this group has been divided between the Cerastipsocinae, with antennae usually much longer than the fore wing, and Psocinae sensu stricto, with antennae usually shorter than or only slightly longer than the fore wing. The Indo-Australian Cycetes has vein R4+5 in the fore wing recurved to touch vein M whereas other psocines have this vein free (New & Lienhard 2007).

Characters (from New & Lienhard 2007): Fore wing vein M comprising distal border of discoidal cell usually concave or straight, only rarely convex. Male hypandrial sclerites confined or largely confined to sternite 9; sternite 8 never wholly sclerotised, so male abdomen apex not ‘encapsulated’; parameres forming a closed frame or frame open posteriorly, never divergent or thickened distally; apophysis of male paraproct with pointed apex. Female with apex of dorsal gonapophysis valve variable.
