description: Tusitala ansieae sp. n.
Figs 9, 10, 14–30
Etymology:This species is named after the South African arachnologist, Dr Anna Sophia (Ansie) Dippenaar-Schoeman, for her life-long contribution to African arachnology.
Diagnosis: Males of T. ansieae sp. n. resemble T. lutzi and can be distinguished from it by the large retrolateral process of the tegulum, the shape of the tibial apophysis – straight instead of curved (Figs 14–16), and the position of the cheliceral process – near the medial border of the chelicerae in T. ansieae sp. n. (Figs 25, 26) instead of the lateral border in T. lutzi (see WesoŁowska 2012: fig. 57). Females resemble T. lyrata and can be distinguished from it by the shorter insemination ducts and their different course (Figs 17–19) (see WesoŁowska & Tomasiewicz 2003: figs 15–19 for T. lyrata).
