Family Psocidiidae Tillyard, 1926

Remark. This family currently comprises six valid genera, but only three of them can be accurately considered as Permopsocida , viz. Dichentomum Tillyard, 1926 , Stenopsocidium Tillyard, 1935 , Hypopsylla gen. nov. Carpenter (1992) synonymized Parapsocidium Zalessky, 1937 with Dichentomum without clear explanation. The other genera of uncertain affinities are Megapsocidium Tillyard, 1935 , Austropsocidium Tillyard, 1935 , and Liassopsocus Ansorge, 1996 . The family is currently known from Australia, possibly Central Europe, Russia, and USA ( Tillyard 1926, 1935; Zalessky 1937; Ansorge 1996).

Diagnosis (after Huang et al. 2016). Fore- and hindwing with very similar venation; ScP long, ending on RA distal of base of RP in four wings; RP two-branched; M four-branched; areola postica longer than high; no crossvein between M and CuA1. At least Dichentomum has small crossveins between costa and ScP.
