Trichadenotecnum cynostigmus (Li) n. comb.
Cryptopsocus cynostigmus Li, 2002: 1459 (in Chinese); 1900 (in English). Note: The species name, based on the Latinized Greek noun “stigmos”, is an invariable noun in apposition.
Distribution. China (Hainan Is.).
Remarks. The only known specimen, the male holotype, of this species has not been examined but, judging from the original description and its original generic assignment (see Introduction), this species is clearly a member of the genus Trichadenotecnum because of the apomorphic forewing markings and some venational characters unique to this genus (Yoshizawa, 2001). Diagnostic characters of this species are discussed below (see Remarks to the other species of the group)
