Atropetae is an infraorder of small insects within the suborder Trogiomorpha of Psocodea, the order containing barklice, booklice, and parasitic lice. It was established by Pearman in 1936. Members of Atropetae are part of the earliest-diverging lineage of Psocodea, retaining primitive characteristics compared to other groups. The infraorder includes of primarily free-living found in cryptic .

Habitat
within Atropetae inhabit cryptic, sheltered environments including leaf litter, bark crevices, caves, and mammal nests. These microhabitats provide the stable humidity conditions required by these small, soft-bodied insects.
Diet
Members feed on organic detritus, including fungal spores, lichen fragments, and decaying plant material. This detritivorous feeding strategy is characteristic of the primitive grade represented by Atropetae.
Ecological Role
Atropetae contribute to nutrient cycling in forest floor and cave through consumption and processing of organic detritus and fungal material. Their role as early colonizers of decaying matter facilitates decomposition .
Similar Taxa
- Trogiomorpha (other infraorders)Atropetae can be distinguished from other infraorders within Trogiomorpha (specifically Psocathropetae) by differences in wing venation patterns and tarsal segmentation. Atropetae retains more primitive characteristics including reduced wing specialization.

Taxonomic Position
Atropetae is one of two infraorders within the suborder Trogiomorpha, the other being Psocathropetae. Trogiomorpha itself is widely accepted as the earliest-diverging of the three major suborders, making Atropetae among the most phylogenetically primitive living lineages of Psocodea.
