Abstract: Thyene roeweri sp. nov. Fig. 54 Diagnosis. This species resembles Thyene mutica (Simon, 1902) slightly, but can be recognized by the tibial apophysis, which is longer and has a serrated tip, while it is shorter and pointed in T. mutica. Thyene roeweri sp. nov. also has a more rounded carapace and slightly different abdominal pattern (compare Fig. 54A with fig. 29 in Azarkina & Foord 2013). Female unknown. Etymology. This species in named after the famous German arachnologist, Carl Friedrich Roewer, who collected many spiders in the Tete Province of Mozambique. Type material.
