A new species of the tracheline sac spider genus Poachelas Haddad & Lyle, 2008 (Araneae: Corinnidae), presently known only from southern Africa, is described. The genus has been represented by three species, all of which are suspected to be closely associated with grasses. The new species described here, P. refugus sp. n., is known only from females collected at the type locality, Tembe Elephant Park in Maputaland, South Africa. New collecting records of the type species of the genus, P. striatus Haddad & Lyle, 2008, described from three localities in the central Free State Province of South Africa and with a distribution range of about 100 km, are presented. The species is widespread throughout the province, and is also recorded from the Eastern Cape, Northern Cape and Mpumulanga provinces for the first time, expanding its range to approximately 900 km.
