Orthobula radiata Simon, 1897b: 499 (Holotype ♂: SOUTH AFRICA: Gauteng: Hammanskraal   GoogleMaps [25°24’S, 28°17’E], deposited in MNHN—examined).

Remark. The locality indicated on the label of the holotype is Hammanskraal, as indicated in the bibliography above, but in the publication ( Simon 1897b) it is indicated as Pretoria (25°42’S, 28°13’E), with about 50 km separating the localities.

Diagnosis. Females of O. radiata have a similar general epigyne structure to O. calceata , but lack the anterior ridges seen in the latter species ( Fig. 65 View FIGURES 65–69 ), with these being replaced by shallow depressions ( Figs 45 View FIGURES 45–53 , 96 View FIGURES 96–100 ), and also by the short CD. Males of O. radiata most closely resemble those of O. milloti , particularly in the short, straight spike-like embolus, but can be distinguished by presence of a bifid ( Fig. 100 View FIGURES 96–100 ) as opposed to a simple finger-like RFA ( Fig. 95 View FIGURES 90–95 ).

Female (Pretoria, NCA 2008/1981). Measurements: CL 1.09, CW 0.83, AL 1.35, AW 1.08, TL 2.55 (1.60– 2.55), PERW 0.36, MOQAW 0.15, MOQPW 0.18, MOQL 0.16. Length of leg segments: I 0.73 + 0.27 + 0.65 + 0.57 + 0.29 = 2.51; II 0.63 + 0.25 + 0.51 + 0.49 + 0.26 = 2.14; III 0.52 + 0.24 + 0.40 + 0.44 + 0.25 = 1.85; IV 0.66 + 0.25 + 0.60 + 0.67 + 0.33 = 2.51.

Colour: carapace deep orange-brown, with black mottling around margins, faint on sides; chelicerae orangebrown; endites orange-brown, labium darker brown, both cream distally; sternum orange, margins orange-brown; palps yellow-brown; legs with femora, patellae and tibiae orange-brown, with dense black mottling laterally; distal ends of femora and tibiae, and basal end of patellae, with yellow rings; metatarsi and tarsi yellow, metatarsi with faint black mottling; abdomen black dorsally, with pair of oval cream anterolateral patches and transverse cream band at midpoint, merging centrally to form X; posterior half with six slender transverse chevrons, last four merging centrally; venter creamy-grey; spinnerets cream.

Epigyne with lateral CO in shallow depressions ( Figs 45 View FIGURES 45–53 , 96 View FIGURES 96–100 ); CD curving posteromesally, entering slightly ovoid SBB at centre of epigyne; SBB almost touching along their mesal surfaces; CD similar in length to width of SBB; BU broad, ovoid, with boomerang-shaped accessory gland on their anteromesal surface; SBB connected to ST I by short looping ducts, entering obliquely-orientated oval ST I on their posteromesal surface ( Fig. 97 View FIGURES 96–100 ).

Male (Pretoria, NCA 2008/1980). Measurements: CL 0.86, CW 0.70, AL 0.95, AW 0.73, TL 1.85 (1.48–2.05), PERW 0.30, MOQAW 0.12, MOQPW 0.16, MOQL 0.15. Length of leg segments: I 0.59 + 0.22 + 0.52 + 0.46 + 0.26 = 2.09; II 0.53 + 0.21 + 0.41 + 0.39 + 0.24 = 1.78; III 0.43 + 0.19 + 0.30 + 0.38 + 0.22 = 1.52; IV 0.57 + 0.20 + 0.49 + 0.56 + 0.29 = 2.11.

Colour: carapace deep orange-brown, mottled around margins, with black mottled marking centrally; chelicerae orange-brown; endites and labium orange-brown, cream distally; sternum orange, margins orange-brown; palps orange-brown, with faint black mottling; legs with femora, patellae and tibiae I and II orange-brown, metatarsi and tarsi yellow-brown, patellae and tibiae with black mottling dorsally and laterally; femora, patellae and tibiae III and IV yellow-brown, metatarsi and tarsi yellow, patellae and tibiae with black retrolateral stripe; abdomen black dorsally, with pair of oblique cream anterolateral markings, converging and merging centrally with transverse cream band; venter and spinnerets cream.

Leg spination: femora and patellae: spineless; tibiae: I plv 6 rlv 5, II plv 4 rlv 4; metatarsi: I plv 4 rlv 4, II plv 4 rlv 4; tarsi: I plv 3 rlv 3, II plv 3 rlv 2.

Palpal femur with small bifid RFA, proximal branch sharply hook-shaped, distal branch small, tooth-like ( Fig. 100 View FIGURES 96–100 ); tibia with small, simple triangular apophysis; retrodistal tegular ridge strongly developed, curving around ventrally, ending close to base of embolus ( Fig. 99 View FIGURES 96–100 ) embolus narrow, straight, spike-like, with slightly constricted tip ( Figs 98–100 View FIGURES 96–100 ).
