Mesopsocus immunis, photographed by Dioctria (David).

Belongs within: Homilopsocidea.
Contains: Peripsocidae, Philotarsidae.

The Peripsocoidea are a clade of bark or stone-surface dwelling barklice, females of which have a strongly sclerotised and square-shaped dorsal valve to the gonapophyses (Yoshizawa 2002). Members include the Mesopsocidae, bark-dwelling species characterised by long, thirteen-segmented antennae and glabrous wings (at most with a few minute marginal setae) (New & Lienhard 2007).

Characters (from Yoshizawa 2002): Small to large in size, about 2–5 mm in length. Body whitish in ground colour with blackish-brown markings or wholly blackish-brown. Head with rounded vertex; postclypeus well bulged; epicranial suture with (Mesopsocidae) or without broad internal ridge; anteclypeus sclerotized or not (Mesopsocidae). Forewing coloration, venation, and ciliation variable. Hindwing ciliation variable; Rs and M + Cu separate (most Mesopsocidae), or fused for short (Philotarsidae) or long (Peripsocidae) distance basally; Rs and M fused. Tarsi 2- (Peripsocidae) or 3-segmented; claws with preapical tooth; pulvillus narrow. Abdomen without eversible vesicles ventrally. Male genitalia: hypandrium usually simple except Philotarsus. Phallosome variable; aedeagus rounded (most of Mesopsocidae and Philotarsidae) or pointed apically; phallobase united and rounded apically; endophallus with (Bryopsocidae, Peripsocidae, and some Philotarsidae) or without sclerites. Female genitalia: epiproct usually rectangular in dorsal aspect except rounded in Bryopsocidae. Subgenital plate with 1-lobed egg guide extended from dorsal margin. Gonapophyses complete; ventral valve and dorsal valve strongly united, forming ovipositor; dorsal valve strongly sclerotized, somewhat rectangular in lateral aspect, with or without (Peripsocidae) subapical process; external valve variable.
