Hemipsocus parallelicus, sp. nov. (figs, 1, 2)Holotyp ,paratype 1 , Mengla Co, (County) (800m),Yunnan Prov. (Province), 1989-IX-10.Habitat: On tree trunk ;on stone,and base of a wall.This new species resembles Hemipsocus ornatus Datta, 1969,but differs from the latter in forewing Rs and M in joined by a crossvein,and with 5 cross bands, epiproct broader and shorter.2. Metahemipsocus cunestus, sp. nov, (figs. 3, 4).Holotyp , Mengla Co. (560m), Yunnan Prov., 1993-Ⅳ-25 ; paratype 1 Mengla Co. (660m),1993-Ⅳ-21.Habitat: in the heap of dead branches and fallen leaves.This new species is similar to Metahemipsocus recuvicornis (Li, 1992 ), comb. nov. (from Hemipsocus ), but is well separable from the latter by the hypandirum sclerotized difference ; IO/D=2. 16 and psotclypeus smaller.3. Metahemipsocus spilopterus.sp.nov. (figs. 5, 6 )Holotype , paratype , Jinghong Co.
