Permopsocida is an extinct order of insects known from the Carboniferous (Moscovian) to the Mid-Cretaceous.

Within Paraneoptera it is considered to be closer to the clade containing bugs and thrips rather than bark lice, with an estimated divergence during the Late Carboniferous.

The group was first named as a suborder by Robert John Tillyard in 1926, and was raised to a full order by Huang et al. in 2016.

Permopsocidae which is only known from the Permian, and Archipsyllidae, which is known from the Late Triassic[2] to mid-Cretaceous (Cenomanian).

[1][3][4][5] The morphology of the mouthparts suggests that they were capable of suction feeding and chewing, with preserved angiosperm pollen grains in the gut of Psocorrhyncha suggesting that at least some members of the group were pollenivorous.
