description: Afroceto capensis sp. n.   Figs 7, 8, 56–61  
Etymology: This species is named after the Western Cape Province, where the entire type series was collected.  
Diagnosis: The female can easily be recognised by the M­shaped anterior epigynal hood (Fig. 56). It has ST II that appear bilobed and are obscured by the large posterior subtriangular ST I (Figs 57, 58). The male of this species can easily be recognised by the well curved retrolateral embolus and the sharply pointed tapering prolateral tegular extension (Fig. 60).  
Description:  
 Female.   
Measurements: CL 2.60–2.70, CW 2.10–2.28, AL 2.80–3.80, AW 1.90–2.50, TL 5.80–6.50, FL 0.15–0.20, SL 1.60–1.65, SW 1.25–1.38, AME–AME 0.13, AME–ALE 0.08, ALE–ALE 0.45, PME–PME 0.13, PME–PLE 0.18, PLE–PLE 0.75. Length of leg segments (sequence from femur to tarsus, and total): I 2.43+1.10+1.85+1.55+1.10=8.03; II 2.20+1.05+1.51+1.50+1.00=7.26; III 1.58+0.83+1.10+1.40+0.58=5.49; IV 2.38+0.98+ 1.85+2.23+0.68=8.12.  
 Carapace reddish brown to dark brown (Fig. 7); first third of carapace rising gradually to highest point, declining gradually in last two thirds; surface slightly granulated, covered in short, fine setae; fovea at two thirds CL. Ocular region dark brown to almost black with black rings around eyes; AER slightly recurved, AME slightly larger than ALE; clypeus height equal to AME diameter; AME separated by distance equal to their diameter; AME separated from ALE by 0.4 AME diameter; PER recurved, PLE slightly larger than PME; PME separated by distance equal to their diameter; PME separated from PLE by 1.2 PME diameter. Chelicerae reddish brown, dark brown near fang base; anterior surface with scattered black setae, setae longer towards fang base; fang dark orange at base, bright orange at tip; three promarginal teeth, median tooth largest, distal tooth smallest; two retromarginal teeth, distal tooth largest. Sternum dark brown, almost black near border, appearing mottled; surface texture granular, covered in scattered long, dark setae. Abdomen creamy yellow dorsally, with dark grey mottled pattern over entire abdomen; abdomen broader anteriorly, tapering posteriorly; surface smooth, with short fine setae throughout; venter cream. Legs I to IV uniform yellow to brown; anterior legs darker, more robust than posteriors; femora to metatarsi with incomplete grey bands covering almost entire segment on legs I to IV; bands on anterior leg segments grey, light brown on posterior leg segments; tibiae, metatarsi and tarsi with dense scopulae. Leg spination: femora: I pl 2; patellae spineless; tibiae: IV rlv 2 vt 2; metatarsi: III pl 1 plv 2 vt 2, IV pl 1 plv 2. Palpal spination: tibia pl 1 do 1. Epigyne weakly sclerotised; anterior epigynal hood M­shaped; epigynal ridges funnel­shaped, with copulatory openings extending into bilobed ST II, partly obscured by larger posterior subtriangular ST I (Figs 56–58).   
 Male.

Length of leg segments (sequence from femur to tarsus, and total): I 2.10+0.95+1.65+1.55+1.38=7.06; II 1.80+0.85+1.48+1.28+0.90=6.31; III 1.33+0.68+ 0.90+1.15+0.45=4.51; IV 1.90+0.75+1.53+1.75+0.63=6.56.  
 Carapace reddish brown to dark brown (Fig. 8); first third of carapace rising gradually to highest point, declining gradually until last quarter, declining steeply in last quarter; surface slightly granulated, covered in short, fine setae; fovea at two thirds CL. Ocular region dark brown with black rings around eyes; AER recurved, ALE slightly larger than AME; clypeus height equal to AME diameter; AME separated by distance equal to 0.6 their diameter; AME separated from ALE by distance equal to 0.4 AME diameter; PER very slightly recurved, PME subequal to PLE; PME separated by distance equal to 0.84 their diameter; PME separated from PLE by distance equal to 0.9 PME diameter. Chelicerae brown, dark brown near fang base; anterior surface with scattered black setae; three promarginal teeth, median tooth largest, proximal tooth smallest; two retromarginal teeth, distal tooth largest. Sternum orange­brown, darkening near border; surface texture smooth, covered in scattered long, fine setae. Abdomen creamy yellow dorsally, with dark grey mottled pattern over entire abdomen; abdomen broader anteriorly, tapering posteriorly; dark brown scutum extends over almost entire length of abdomen; surface smooth, with short fine setae throughout; venter cream. Legs I to IV uniform orange to brown; anterior legs darker, more robust than posteriors; tibiae, metatarsi and tarsi with dense scopulae. Leg spination: femora: I pl 3, II pl 2; patellae spineless; tibiae: I plv 11 cusps, II plv 3 cusps, III plv 3 vt 2, IV plv 2 vt 2; metatarsi: I plv 9 rlv 7 vt 1 cusps, II plv 11 rlv 6 vt 1 cusps, III pl 1 plv 3, IV pl 1 plv 2; tarsi: I plv 7 rlv 10 cusps, II plv 5 rlv 4 cusps (Fig. 59). Palp brown; embolus originating prolaterally, curving beneath large tapering curved prolateral tegular extension, emerging retrolaterally, curving and extending along retrolateral margin to cymbium tip (Fig. 60); retrolateral tibial apophysis parallel sided, directed dorsally, with sharp anterior point (Fig. 61).
