description: Heriaeus foordi sp. n.   Figs 6, 30–33, 58  
Etymology: Named for Stefan Foord of the University of Venda, who collected the holotype. He is recognized for his contribution in recording spider diversity in the African savannah.  
Diagnosis: The species is recognized by a combination of long, dark brown, spiniform abdominal setae (Fig. 6), the small dome-shaped hood of the female epigyne (Fig. 32) and the long embolus with straight tip in the male (Fig. 30). The RTA is long, with a prolaterally curved distal tooth and a basal lobe (Fig. 31).  
Description:  
 Female (allotype).   
 Size: TL 4.61, CL 2.25, CW 2.18. Colour: Carapace yellow-brown, with two broad irregularly shaped longitudinal dark brown stripes; setae dark brown; sternum with white markings; clypeus brown; chelicerae yellow-brown, with brown marks proximally and white marks distally and laterally; eye region white between anterior eyes, brown between posterior eyes; eye tubercles white or greyish white.Abdomen brown dorsally, mottled with white, with dark brown circular marks usually forming a distinct pattern; venter lined with white; laterally with white striae with brown spots. Legs yellow-brown, with white marks on all segments except metatarsi and tarsi. Palp segments all with white markings except tibia with brown markings.

Abdomen: Round, truncated anteriorly; setae long and dark brown or short and transparent. Epigyne: With small dome­shaped hood; internal organs visible as two indistinct bean-shaped structures lying diagonally below hood (Fig. 32); four small dark posterior spots indicate position of fertilization ducts; copulatory ducts two tubes lying diagonally below hood (Fig. 33).   
 Male (holotype).   
 Size: TL 3.18, CL 1.66, CW 1.74. Colour: Carapace yellow-brown, with two broad irregularly shaped longitudinal dark brown stripes; setae dark brown; clypeus brown; chelicerae with brown marks; eye region white between anterior eyes, brown between posterior eyes; eye tubercles white or greyish white. Abdomen yellow-brown, mottled with brown; some males with faint circular pattern similar to that of female; setae dark brown. Legs with white markings on coxae I–IV; leg I (patella to tarsus) much darker than legs II–IV.
