Figs 45 A–F, 46A–F, 47A–F, 48A–F, 49A–F, 50A–F

Type material. Male holotype from D. R. Congo, Albert National Park [Virunga National Park], sect. Ruwenzori, Kalonge, gîte Ruwenzori, Alt. 2080 m, 00°20’N 29°49’E, 24–29 September 1952, P. Vanschuytbroeck & J. Kekenbosch leg., deposited in MRAC 233041. Paratypes: 1 male and 1 female with same data as holotype. (MRCA 223382); 1 male and 1 female from D. R. Congo, Albert National Park (Virunga National Park), sect. Ruwenzori, Kyandolire, camp des gardes, Alt. 1700 m, 00°20’N 29°49’E, 24–25 October 1952, P. Vanschuytbroeck & J. Kekenbosch leg. (MRCA 232924).

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, 50C); 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).

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).
