Permopsocida

Permopsocida is an extinct order of insects known from the Early Permian to the Mid-Cretaceous. It is part of Paraneoptera, alongside bark lice (including lice), bugs and thrips. 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. It is currently divided up into three families, Psocidiidae which is known from the Permian to Liassic. Permopsocidae which is only known from the Permian, and Archipsyllidae, which is known from the Late Triassic to mid-Cretaceous (Cenomanian). While most members of the group are known from compression fossils, several members of Archipsyllidae are 3 dimensionally preserved in Burmese amber, which has helped clarify the morphology and phylogenetic position of the group. 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.
