Prionoglaridids are probably the most basal family of extant psocids and may be considered as living fossils. The genus Afrotrogla gen. n. is described for three new species from southern Africa, two of them only known from caves: A. oryx sp. n. (South Africa, in cave, type species), A. maraisi sp. n. (Namibia) and A. fabella sp. n. (Namibia, in cave). The male of the second African genus of the subfamily, Sensitibilla Lienhard, is described for the first time and two new species of Sensitibilla are described, one of them only known from a cave: S. brandbergensis sp. n. (Namibia) and S. roessingensis sp. n. (Namibia, in cave). Some structures of the type species S. strinatii Lienhard are also illustrated. A comparison of these two genera with the third known genus of the subfamily, the North American Speleketor Gurney, shows that the African genera are characterized by some striking synapomorphies in male and female genitalia. Thus a subdivision of the subfamily Speleketorinae in two tribes is proposed: Spelcketorini for Speleketor and Sensitibillini trib. n. for Sensitibilla and Afrotrogla. Among other features, Sensitibillini are characterized by the presence of a trichobothrium on the hindtarsus. Tarsal trichobothria are not known elsewhere in insects. Male and female terminalia of Speleketor irwini Mockford are also illustrated.
