description: Afroceto dippenaarae sp. n.   
Figs 2, 6–8 Etymology: This species is named after Dr Ansie Dippenaar-Schoeman, in recognition of the siGnificant contribution she has made throuGhout her career in the field of Arachnology on the African continent, especially in South Africa.  
 Diagnosis: A. dippenaarae sp. n. and A. porrecta Lyle & Haddad, 2010 both have an elongated embolus and cymbium. These two species are the only Afroceto species with two clearly separated retrolateral tibial apophyses. Afroceto dippenaarae sp. n. is recognised from A. porrecta by the broader, elongated embolus that ends with a folded tip, the less strongly ventrally curved cymbium, and the smaller dorsal retrolateral apophysis (Fig. 8).
