Etymology. The specific name refers to the type locality, noun in apposition.

Diagnosis. Males of K. ruwenzori sp. nov. are distinguished from those of the other species of the genus by the palp with a distally bifid RTA (simple in K. rutshuru sp. nov. and K. buta sp. nov.) ( Figs 49E View FIGURE 49 , 50C View FIGURE 50 ); females differ by the positioning ridges oblique and separated from each other, with an excavated area between the copulatory openings (positioning ridges touching in K. rutshuru sp. nov. and K. buta sp. nov.) ( Fig. 50D View FIGURE 50 ).

Description. Male (holotype). Total length: 2.37. Carapace 1.09 long, 0.78 wide; Abdomen 1.15 long, 0.70 wide; Sternum 0.75 long, 0.56 wide; Spinnerets: ALS 0.26 long, 0.14 wide. Eye diameters: AME 0.05, ALE 0.04, PME 0.03, PLE 0.04; interdistances: AME–AME 0.03, PME–PME 0.06. Chelicerae 0.30 long. Leg measurements: I: 3.42 (0.92, 0.72, 0.74, 0.54, 0.50); II: 2.46 (0.68, 0.40, 0.52, 0.44, 0.42); III: 2.43 (0.70, 0.35, 0.46, 0.44, 0.48); IV: 3.50 (0.95, 0.50, 0.80, 0.65, 0.60). Leg spination: I—femur d1-1-0; metatarsus v0-2-0. II—femur d1-1-0. III—femur d1-1-0; tibia v2-0-2, p1-0-1, r1-0-1; metatarsus v0-2-0, p0-0-1. IV—femur d1-1-0; tibia v1-1-1; metatarsus v0- 1-1. Palp: tegulum ovoid; proximal part of reservoir close to embolar base; embolar insertion between 8–9 o’clock position; embolus with distal part curved; conductor arising at 12 o’clock position ( Figs 50 View FIGURE 50 A–C).

Female (Paratype). Total length: 2.19. Carapace 0.84 long, 0.59 wide; Abdomen 1.28 long, 0.70 wide; Sternum 0.62 long, 0.47 wide; Spinnerets: ALS 0.25 long, 0.14 wide. Eye diameters: AME 0.04, ALE 0.03, PME 0.04, PLE 0.03; interdistances:AME–AME 0.03, PME–PME 0.03. Chelicerae 0.25 long. Leg measurements: I: 2.47 (0.65, 0.52, 0.54, 0.40, 0.36); II: 2.02 (0.60, 0.35, 0.40, 0.35, 0.32); III: 1.68 (0.48, 0.25, 0.31, 0.30, 0.34); IV: 2.64 (0.70, 0.34, 0.60, 0.54, 0.46). Leg spination: I—femur d1-0-0. II—femur d1-1-0; metatarsus v0-2-0. III—femur d1-1-0; tibia v1- 0-1p; metatarsus v0-1p-0. IV—femur d1-1-0; tibia v1-1-1, p1-0-1; metatarsus v0-2-0, p0-0-1. Vulva: copulatory duct with only one curve; connecting duct with proximal and terminal parts very close to each other, with twist at terminal part (close to primary spermathecae); primary spermathecae ovoid; fertilization duct anteriad ( Figs 50E, F View FIGURE 50 ).

Variation. Total length (3 males): 1.75–2.37; (6 females): 1.70–2.32. In some females the secondary spermathecae are in parallel to each other.

Distribution. Virunga National Park, D.R. Congo ( Fig. 53 View FIGURE 53 ).
