Remarks. A widespread species recorded from seven of the nine South African provinces, as well as Mozambique ( Dippenaar-Schoeman et al. 2021), T. africana was originally described from the Matroosberg Mountains near Ceres in the Western Cape ( Tucker 1923). The relationships of the species remain obscure as the male has not yet been described, although we provide images of it ( Figs 76–83 View FIGURES 76–83 ). Even though the species shares a variety of characters with other members of Trichothyse , including a male dorsal abdominal scutum ( Fig. 76 View FIGURES 76–83 ), the scopulated anterior parts of metatarsi and tarsi ( Figs 80 View FIGURES 76–83 , 88 View FIGURES 84–89 ), and females with a keel on the cheliceral promargin ( Fig. 87 View FIGURES 84–89 ), males differ in several respects: 1) cheliceral promargin with distinct teeth and not a keel ( Fig. 79 View FIGURES 76–83 ); 2) absence of a curved distal membranous conductor ( Figs 82–83 View FIGURES 76–83 ); 3) palp with a simple RTA without an additional protuberance on its dorsal surface ( Figs 82–83 View FIGURES 76–83 ); 4) clearly different embolus shape, with sharp and angular sclerotisations terminating apically ( Figs 82–83 View FIGURES 76–83 ); 5) presence of a distinct hooked median apophysis, positioned close to the embolus ( Figs 82–83 View FIGURES 76–83 ); 6) lack of a tooth on the cheliceral retromargin in females ( Fig. 87 View FIGURES 84–89 ), although present in males ( Fig. 79 View FIGURES 76–83 ); 7) narrow sperm duct in the male palp ( Figs 82–83 View FIGURES 76–83 ); and 8) habitus of yellow-brown colouration ( Figs 76 View FIGURES 76–83 , 84 View FIGURES 84–89 ).

Considering the groupings proposed by Murphy (2007), T. africana clearly belongs to the “ Echemus group” of genera, but its affinities and possible placement remain unclear. If it represents a new genus, such a description would wait pending further taxonomic investigation, including related undescribed species, and stronger support, including molecular data.
