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

Diagnosis. Males of K. buta sp. nov. are distinguished from the other species of the genus by the presence of a VTA on palp in addition to the RTA (VTA absent in K. ruwenzori sp. nov. and K. rutshuru sp. nov.) ( Figs 52 View FIGURE 52 A–C); females differ by the positioning ridges resembling a mustache ( Fig. 52D View FIGURE 52 ).

Eye diameters: AME 0.04, ALE 0.03, PME 0.04, PLE 0.03; interdistances: AME–AME 0.02, PME–PME 0.05. Chelicerae 0.31 long. Leg measurements: I: 3.21 (0.89, 0.64, 0.66, 0.55, 0.47); II: 2.50 (0.66, 0.42, 0.54, 0.45, 0.43); III: 2.27 (0.60, 0.34, 0.46, 0.42, 0.45); IV: 3.33 (0.95, 0.46, 0.70, 0.66, 0.56). Leg spination: I—femur d1-1-0. II—femur d1-1-0. III—femur d1-1-0; tibia v1-0-1, p1-0-1; metatarsus v0-2-0, p1-0-1. IV—femur d1-1-0; tibia v1p-1p-2, p1-0-1, r1-0-1; metatarsus v1-1-0, p0-0-1, r0-1-0. Palp: single RTA with tip slightly truncated and ventrally bent; tegulum ovoid with distal region narrower than basal region; embolar insertion at 10 o’clock position; embolus with distal part straight; conductor arising between 12–1 o’clock position, directed retrolaterally ( Figs 52 View FIGURE 52 A–C).

Female (paratype). Total length: 2.25. Carapace 0.76 long, 0.62 wide; Abdomen 1.39 long, 0.70 wide; Sternum 0.57 long, 0.47 wide; Spinnerets: ALS 0.16 long, 0.11 wide. Eye diameters: AME 0.04, ALE 0.04, PME 0.03, PLE 0.03; interdistances: AME–AME 0.02, PME–PME 0.04. Chelicerae 0.22 long. Leg measurements: I: 2.52 (0.68, 0.52, 0.52, 0.44, 0.36); II: 1.93 (0.53, 0.32, 0.40, 0.35, 0.33); III: 1.71 (0.46, 0.24, 0.34, 0.33, 0.34); IV: 2.71 (0.75, 0.39, 0.60, 0.52, 0.45). Leg spination: I—femur d1-1-0. II—femur d1-1-0. III—femur d1-1-0; tibia p1-0-1; metatarsus v0-1-1, p0-0-1. IV—femur d1-1-0; tibia v1p-0-1p, p1-1-0, r1-0-1; metatarsus v0-1-1, p0-0-1, r0-0-1. Epigyne: positioning ridge directed posteriorly ( Fig. 52D View FIGURE 52 ). Vulva: copulatory ducts with one curve, connecting duct with proximal and terminal part far from each other and without twist in terminal part (close to primary spermathecae); primary spermathecae rounded; fertilization duct directed diagonally ( Figs 52E, F View FIGURE 52 ).
