Holotype:female, SOUTH AFRICA, Eastern Cape Province, Stormsriver, Tsitsikamma National Park, 34°01'S: 23°53'E, coastal forest, leaf litter, 5 December 2012, leg. J.A. Neethling( NCA 2013/655).
Diagnosis.This species is characterized by the very dark coloration of the body. The female epigyne is similar to that in T. wesolowskae Zhang & Maddison, 2012but differs by the presence of the accessory glands (lack in the latter species), the clearly narrower and shorter seminal ducts and the bean shaped spermathecae (versus rounded in T. wesolowskae).
Etymology.The specific name is Latin for dark and refers to the colouration of this spider.
