This paper deals with one new genus and two new species of psocids belonging to Lepidopsocidac and Psyllipsocidac of Trogiomorpha. All specimens arc collected from Yunnan Province, China. Type specimens arc kept in the Insect Collection of Beijing Agri-cultural Uninersity.LepidopsocidacGenus Ille pido pxoeus, gen. nov.Type species: Ille pido psocus yunnanicus, gen. et sp. nov.Body and wings covered with setae. Median epicranial suture with dcstincl anterior arms. 3 ocelli widely spaced; eyes large. Fourth segment of maxillary palp hatehet-shaped. Forewings narrow, elongated and pointed. Basal and distal section of Sc well developed.R1 and Rs connected by a cross vien. M3 near Rs and M fordked; with 2 anal veins.Hind wings elongated, pionted, with a closed basal cell, Sc well developed. R1 arises proximal of M1; M+Cu1basally separated from R , M1 and M2 arises separately from R+M. Cu1 not forked, with 1 anal vein. Veins and membrance, especially in distal part of wings, setose, margin with long haires. Claws with 1 prcapical tooth; pulvillus slender, expanded apically. Subgenital plate simple. Gonapophyscs reduced to an elongated round end, apicaly with a long and stout seta, external valve with setae.Habitat: in dead leaves and branches.Distribution: China: Yunnan Province.This new genus is similar to Thylacella Endcrlcin, 1911, but differs from the latter by R1 of hind wings arising proximal of M1, M1 and M2 separately arising from M+R and claws with 1 preapical tooth.Ille pido psocus yunnanicussp. nov.

(fig. 2)Holotype (?), paratype 1 (?), Mengla Co. (50m) Yunnan Prov., 1993-VII Habitat: in dried leaves and branches.This new species differs from Psocathropos microps (Endcrlein, 1903) in hind wings without R cell and with smaller Cula cell.
