PSEUDOCAECILIOIDEA , SUPERFAM. NOV.

All three included families of this superfamily were simultaneously established by Pearman (1936) and a name could not be decided by the principle of priority. I propose Pseudocaecilioidea since Pseudocaecilius has the widest distributional range among the type genera of the three families.

Small to middle in size, about 2–4 mm. Coloration variable. Usually living-foliage dwellers, except for some genera of Pseudocaeciliidae (e.g. Ophiodopelma ).

Vertex generally rounded but strongly angled in Calopsocidae ; postclypeus not strongly bulged; epistomal suture faint dorsally, without broad internal ridge; anteclypeus sclerotized. Forewing veins with more than one row of setae; marginal setae crossing on anterior margin or not ( Trichopsocidae ). Apex of first axillary sclerite broadened. Hindwing veins and margins setose; Rs and M + Cu separate or fused for short distance basally; Rs and M fused. Tarsi usually 2- segmented; claws with or without preapical tooth; pluvillus broad. Abdomen with eversible vesicles ventrally except some dead-foliage dwelling taxa in Pseudocaeciliidae . Male genitalia: hypandrium articulated laterally with clunium or not ( Trichopsocidae ); with or without ( Trichopsocidae ) lateral projection and lateral bristle. Phallosome: aedeagus pointed apically; parameres long, extending far beyond aedeagus; endophallus with or without ( Trichopsocidae and some genera of Pseudocaeciliidae ) rod-like sclerites. Female genitalia: subgenital plate with well-developed egg guide extending from dorsal margin; egg guide 2-lobed, each bearing 1 or 2 apical setae. Gonapophyses complete; ventral valve usually with dorsal lobe apically; dorsal valve with dorsal lobe and subapical process; external valve variable, bearing many long bristles.

Type genus: Pseudocaecilius Enderlein, 1903 .

Included families: Trichopsocidae , Calopsocidae , Pseudocaeciliidae .
