Diagnosis.
Very similar to T. pumila sp. nov. but larger (e.g., body length 1.76/2.23 ♂/♀ versus 1.56/1.96 ♂/♀ in T. pumila sp. nov.; femur length 0.49/0.61 ♂/♀ versus 0.44/0.53 ♂/♀ in T. pumila sp. nov.); more slender femora (1.66/1.69 ♂/♀ times longer than broad versus 1.63/1.63 ♂/♀ in T. pumila sp. nov.).
Etymology.
This species is a patronym honoring Volker Mahnert who worked on African pseudoscorpions.
