The Caeciliusetae are a clade of barklice characterised by the absence of a preapical tooth on the pretarsal claw, and reduction of the external valve of the gonapophyses. Members of the clade are divided between the small bark-dwelling family Asiopsocidae and the more diverse foliage-dwelling Caeciliusoidea (Yoshizawa 2002). Members of Caeciliusoidea have elongate mandibles that are posteriorly excavated whereas Asiopsocidae retain short to medium-length mandibles (Mockford 1993).
Characters (from Yoshizawa 2002): Small to large in size, about 2–10 mm in length. Sexual dimorphism present. Head with rounded vertex; eyes variable; ocelli complete, clustered on small tubercle; mandible more or less elongate, outer margin angled; galea ball-shaped; labial palpus somewhat triangular. Prothorax less bulged dorsally; preepisternum of prothorax elongate. Pterothorax greatly bulged dorsally in winged form; mesothorax with broad precoxal bridge and narrow trochantin; metathorax with broad membranous region. Forewing variable in venation, size, shape, and colour; posteroproximal corner smoothly rounded. Hindwing with smoothly rounded posteroproximal corner; ciliation variable; Sc clear; Rs and M + Cu fused for long distance basally; Rs and M fused. Tarsi 2-segmented; claws without preapical tooth. Male genitalia: Hypandrium simple, posterior margin smoothly rounded. Phallosome: aedeagus pointed apically, strongly arched in lateral aspect; paramere extended along aedeagus, strongly arched in lateral aspect; phallobase simple and narrow, anterior margin not divided; endophallus usually with weakly sclerotized region but never with rod-like sclerites. Female genitalia: Subgenital plate simply rounded or slightly hollowed posteriorly. Gonapophyses variable; external valve more or less reduced.
