Males of this species are characterised by details of the palp (Figs 4 A, B, 5 A, B): the distal spine-shaped part of the dorsal tibial prong is directed forward at an angle of 90 ° with the base of the apophysis; the cymbium has a wide, S-shaped fold of which the distal part is particularly deep and curved upwards; females are recognized by the epigyne with scape strongly widened apically ending in the middle and the complex copulatory duct with six loops visible in transparency along its course (Figs 4 C – E, 5 C). Etymology. The specific name is a patronym in honour of our friend and colleague, the late Stefan Foord, who was a dynamic arachnologist and driving force for arachnology in South Africa and beyond. Description. Male Holotype. Figs 3 A – C, 6 C – E. Total body length 2.77. Colour in ethanol: carapace uniform medium brown with narrow dark rings around eyes and W-shaped dark area in front of fovea; chelicerae, endites and labium medium brown; sternum medium brown with darker margin; legs: femora pale with dark anterior stripes on Fe I – IV and dark posterior stripe on Fe III and IV in distal two thirds; abdomen: dorsum dark grey with narrow dark brown scutum in anterior half, 13 tiny white spots (Fig. x); sides dark with oblique white streak; venter pale, narrow yellowish patch in front of white spinnerets and yellow in front of epigastric fold.

All femora with one short dorsal spine in proximal half. Legs: measurements in Table 2. Palp (Figs 4 A, B, 5 A, B): very large: length including Ti 0.8 times carapace length. Tibia with three apophyses: dorsal prong (DP) broad, directed up, slightly curved forward, with distal spine shaped tip pointing forward at an angle of 90 °; median prong (MP) shorter, curved downward with rounded extremity, with sharp triangular extension visible by transparency (Ex); inferior one (VP) short, straight with rounded extremity; cymbium laterally compressed with large lateral S-shaped fold (CF), its distal curve deep and directed upwards; tegulum with two appendages: largest one, mainly visible prolaterally; second one pear-shaped with long tapered forward directed prong; median apophysis (MA) subcircular with short rounded lip directed forward; conductor (C) large, directed forward; embolus long and whip-shaped originating on dorsal side of tapered posterior end of roughly triangular base.

Legs without spines; measurements in Table 3. Epigyne (Figs 4 C – E, 5 C): rectangular area slightly wider behind than in front; scape (Sc) widened towards posterior part situated in the centre of the epigyne, its tip slightly indented, copulatory openings (O) situated in posterior half; copulatory ducts narrow, strongly wound, with six loops visible in transparency; very complex internal structure with many loops mainly longitudinal in posterior part, mainly transverse in anterior part. Variation. South Africa: Males (n = 5): TL 2.77–3.00, CL 1.28–1.50; white spots on dorsum 11–13. Females (n = 11): TL 2.70–3.83, CL 1.21–1.68; white spots on dorsum 13–16. The shape of the small spots may vary from circular to elongate oval. DR Congo: Males (n = 2): TL 2.63–2.77, CL 1.35–1.42; dorsum in the centre with two transverse rectangular white spots. Female (n = 1): TL 2.51, CL 1.21; dorsum as in males. Guinea: Male (n = 1): TL 2.59; CL 1.44. Abdominal pattern as in type series. Distribution. The species is known from South Africa, DR Congo and Guinea (Fig. 24).
