Trichopsocidae

Definition

A small family of barklice and booklice (order Psocodea, suborder Psocomorpha) comprising approximately 11 described species in two genera. Members of this family are typically found in tropical and subtropical habitats, often associated with lichens, mosses, or decaying vegetation on tree trunks and rocks. The family is characterized by specific wing venation patterns and body setation that distinguish it from related psocid families such as Psocidae.

Etymology

From Greek trichos (hair) + Psocidae (type family of Psocodea), referring to the hairy or setose appearance characteristic of these insects.

Example

Trichopsocus brincki, a South African species in Trichopsocidae, exhibits the family's diagnostic trait of reduced areola postica in the forewing, a feature used to separate it from the more speciose family Psocidae.

Usage Notes

Use only for the family rank; do not confuse with the similar-sounding genus Trichopsocus. The family's small size and tropical distribution make it less frequently encountered in temperate entomological collections compared to the larger families Psocidae or Caeciliusidae.
