Prokop, Jakub, Garrouste, Romain & Nel, André, 2016, A new permopsocidan genus and species from the Late Permian of Australia (Insecta: Acercaria: Psocidiidae), Zootaxa 4147 (5), pp. 589-592 : 590

Hypopsylla gen. nov.

Type species. Hypopsylla belmontensis sp. nov.

Diagnosis. Wing characters only. ScP ending on RA distal of base of RP, but closer to this point than to the pterostigma (a character also present in Permopsociidae but not in Archipsyllidae ); presence of a short crossvein between ScP and costa; a very deep posterior curve of RA in the pterostigma; posterior branch of M with three branches; elongate and narrow areola postica (a character also present in Archipsyllidae but not Permopsociidae), absence of crossvein between M and CuA (a character also present in Archipsyllidae but not Permopsociidae).

Etymology. Composite name after Hypoperla and Archypsylla. Gender feminine.

Remark. The new genus Hypopsylla ( Upper Permian , Australia, H. belmontensis ) shares with the Psocidiidae the elongate and narrow areola postica, presence of a short crossvein between ScP and costa as in Dichentomum , ScP ending on RA distal of base of RP, but closer to this point than to the pterostigma, unlike in other taxa of this family.
