Trichadenotecnum Enderlein

For definition and synonymy see: Yoshizawa (2001, 2003), Yoshizawa et al. (2007) and Yoshizawa et al. (2008). In addition to the species from Peninsular Malaysia treated below, T. umbratum New & Thornton, 1976 was transferred to Atrichadenotecnum by Endang et al. (2002), and T. marginatum New & Thornton, 1976, judging from the original description, appears to be close to Cryptopsocus cynostigmus Li, 2002 from China, and is therefore not discussed further in this paper.
