Etymology. The specific name refers to the type locality, adjective.

Diagnosis. Males of Yoruba toubensis sp. nov. are distinguished from those of Y. ibadanus sp. nov. by the palp with a laminate embolus, without folds (screw-shaped in Y. ibadanus sp. nov.) and the ventral tibial apophysis pointing retrolaterally in ventral view (straight in Y. ibadanus sp. nov.) ( Figs 60A, D View FIGURE 60 ); females differ from Y. ibadanus sp. nov. by the epigyne lacking an epigynal scape (present in Y. ibadanus sp. nov.), copulatory openings with anterior part sclerotized, forming a hood ( Figs 60E, F View FIGURE 60 ).

Description. Male (holotype). Total length: 2.37. Carapace 0.90 long, 0.61 wide; Abdomen 1.26 long, 0.70 wide; Sternum 0.67 long, 0.49 wide; Spinnerets: ALS 0.19 long, 0.12 wide. Eye diameters: AME 0.04, ALE 0.03, PME 0.04, PLE 0.05; interdistances: AME–AME 0.02, PME–PME 0.03. Chelicerae 0.22 long. Leg measurements: I: 2.73 (0.76, 0.55, 0.55, 0.45, 0.42); II: 1.83 (0.46, 0.30, 0.36, 0.35, 0.36); III: 1.61 (0.44, 0.22, 0.32, 0.30, 0.33); IV: 2.86 (0.75, 0.45, 0.62, 0.55, 0.49). Leg spination: I—femur d1-1-0. II—femur d1-1-0. III—femur d1-1-0; tibia and metatarsus probably with spines, but not visible. IV—femur 1-1-0; tibia v1-1-2, r1-0-1, p1-0-0; metatarsus v0-0-1, p0-0-1. Palp: RTA tapered and directed apically; embolus arising at 8 o’clock position; conductor arising close to center of tegulum ( Figs 60 View FIGURE 60 A–D).

Female. (Paratype). Total length: 2.56. Carapace 1.00 long, 0.62 wide; Abdomen 1.33 long, 0.78 wide; Sternum 0.70 long, 0.55 wide; Spinnerets: ALS 0.23 long, 0.13 wide. Eye diameters: AME 0.04, ALE 0.04, PME 0.04, PLE 0.05; interdistances:AME–AME 0.02, PME–PME 0.03, AME–ALE contiguous, PME–PLE contiguous, ALE–PLE contiguous. Chelicerae 0.27 long. Legs measurements: I: 2.70 (0.76, 0.52, 0.54, 0.46, 0.42); II: 2.31 (0.60, 0.40, 0.47, 0.44, 0.40); III: 1.89 (0.46, 0.30, 0.35, 0.42, 0.36); IV: 2.80 (0.74, 0.45, 0.60, 0.55, 0.46). Leg spination: I—femur d1-1-0. II—femur d1-1-0. III—femur d1-1-0; tibia v0-1p-1p, r0-1-1, p1-0-1; metatarsus v1-0-1, p0-0-1. IV—femur 1-1-0; tibia v1p-2-2, r1-0-1, p1-0-1; metatarsus v1-0-1, r0-1-0, p0-0-1. Vulva: copulatory ducts slightly diverging from one another; primary spermathecae ovoid ( Fig. 60F, G View FIGURE 60 ).
