Trichadenotecnum marginatum New & Thornton

Trichadenotecnum marginatum New & Thornton, 1976: 413 .

Distribution. Malaysia (Peninsula).

Remarks. The only known specimen of this species (male holotype) has not been examined but, judging from the original description, this species is clearly close to T. cynostigmus, the type species of Cryptopsocus treated below, because of the similarity of the hypandrial structures. Diagnostic characters of this species are discussed below (see Remarks to other species of the group).
