Notes

Grichanov (1997) described and figured genitalia of a male from Angola under the name T. prudens , but noted that it differs from the original description of the latter species and from a male collected from Senegal in much shorter cercus, about as long as surstylus. The Angolan male belongs most probably to the new species described here as T. sigwalti sp. nov. So, Angola is excluded from the species area.

Distribution

DR Congo, Ghana, Namibia, Senegal, South Africa, * Tanzania.
