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

Diagnosis. Males of K. rutshuru   sp. nov. are distinguished from those of the other species of the genus by the tegulum with the distal part widened (distal part narrower in K. ruwenzori   sp. nov. and K. buta   sp. nov.), sperm duct far from embolar insertion (very close to embolar insertion in K. ruwenzori   sp. nov. and K. buta   sp. nov.), and the conductor arising between 1–2 o’clock position (at 12 o’clock position in K. ruwenzori   sp. nov. and K. buta   sp. nov.) ( Figs 51B, C View FIGURE 51 ); females differ by the positioning ridges close to each other, almost touching, and by copulatory duct enlarged close to copulatory opening and visible ventrally (narrower in K. ruwenzori   sp. nov. and K. buta   sp. nov.) ( Figs 51D, E View FIGURE 51 ).

Description. Male (holotype). Total length: 2.25. Carapace 0.90 long, 0.75 wide; Abdomen 1.12 long, 0.66 wide; Sternum 0.62 long, 0.51 wide; Spinnerets: ALS 0.25 long, 0.13 wide. Eye diameters: AME 0.06, ALE 0.04, PME 0.06, PLE 0.06; interdistances: AME–AME 0.02, PME–PME 0.04. Chelicerae 0.26 long. Leg measurements: IV: 3.20 (0.85, 0.46, 0.74, 0.64, 0.51). Legs I, II and III lost. Leg spination: IV—femur d1-1-0; tibia v1r-0-2, p1-0-1, r0-0-1; metatarsus r0-0-1. Palp: single RTA with tip curving dorsally; tegulum robust, with distal region larger than basal region, creating large space between reservoir and embolus; embolar insertion between 6–7 o’clock position; embolus with distal part curved ( Figs 51 View FIGURE 51 A–C).

Female (paratype). Total length: 2.46. Carapace 0.94 long, 0.78 wide; Abdomen 1.43 long, 0.84 wide; Sternum 0.72 long, 0.58 wide; Spinnerets: ALS 0.26 long, 0.15 wide. Eye diameters: AME 0.04, ALE 0.03, PME 0.04, PLE 0.04; interdistances: AME–AME 0.04, PME–PME 0.04. Chelicerae 0.29 long. Leg measurements: I: 2.95 (0.77, 0.60, 0.62, 0.51, 0.45); II: 2.40 (0.66, 0.41, 0.49, 0.44, 0.40); III: 2.03 (0.56, 0.34, 0.40, 0.36, 0.37); IV: 3.32 (0.94, 0.48, 0.70, 0.64, 0.56). Leg spination: I—femur d1-1-0. II—femur d1-1-0; tibia v0-2-0. III—femur d1-1-0; tibia v1p-0-1p, p1-0-1; metatarsus v0-2-0, p0-0-1. IV—femur d1-1-0; tibia v1p-2-2, p1-0-1, r1-0-1; metatarsus v1-1-1, p1-0-1, r0-0-1. Epigyne: positioning ridge directed anteriorly ( Fig. 51D View FIGURE 51 ). Vulva: copulatory duct with three curves; connecting duct with proximal and terminal parts far apart and without twist at terminal end (close to primary spermathecae); primary spermathecae robust; fertilization duct antero-laterad ( Figs 51E, F View FIGURE 51 ).

Variation. Total length (3 males): 1.84–2.25.

Distribution. D.R. Congo and Kenya ( Fig. 53 View FIGURE 53 ).
