A new barklouse species belonging to the Trichadenotecnum s.str. clade (Psocodea: “Psocoptera”: Psocidae) was described from southeastern Brazil (Minas Gerais state). This locality is highly isolated (about 3400 km) from the closest known distributional range of this clade. It also represents the southernmost distributional record of Trichadenotecnum s.str. Phylogenetic placement of the species and biogeography of Neotropical Trichadenotecnum were briefly discussed. Trichadenotecnum punctipenne New, 1972 described from Brazil was synonymized with Trichadenotecnum pardus Badonnel, 1955.
