Figs 37A View FIGURE 37 , 38 View FIGURE 38 A–F, 39A–D, 40C–F, 41A–F, 42A–E

Type material. Male holotype from D. R . Congo, Mayombe, Bas-Congo, Luki Forest Reserve , 05°38’S, 13°04’E, 14 November–2 October 2007, D. De Bakker & J.P. Michiels leg., deposited in MRAC 222770 View Materials GoogleMaps . Paratypes with same data as holotype: 1 male ( MRAC 222538 View Materials ), 1 male ( MRAC 222545 View Materials ) and 1 male ( MRAC 222770 View Materials ); 2 males, 3–14 November 2006 ( MRAC 219931 View Materials ); 1 female, 13 September–23 November 2007 ( MRAC 222702 View Materials ) .

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

Diagnosis. Females of K. mayombensis sp. nov. differ from those from K. langalanga sp. nov. by the epigyne with the posterior margin of the epigynal plate surpassing the epigastric furrow (not surpassing the epigastric furrow in K. langalanga sp. nov.), and copulatory openings under small triangular hood-like ridges (rounded with C-shaped sclerotized margins in K. langalanga sp. nov.) ( Fig. 42D View FIGURE 42 ). Male: see generic diagnosis.

Description. Male (holotype). Carapace and legs orange, abdomen graycolouration in ethanol) ( Fig. 37A View FIGURE 37 ). Total length: 1.72. Carapace 0.74 long, 0.58 wide; Abdomen 0.94 long, 0.56 wide; Sternum 0.56 long, 0.46 wide; Spinnerets ALS 0.13 long, 0.12 wide. Eye diameters: AME 0.06, ALE 0.04, PME 0.04, PLE 0.03; interdistances: AME–AME 0.02, PME–PME 0.02. Chelicerae 0.23 long. Leg measurements: I: 2.49 (0.70, 0.52, 0.55, 0.42, 0.30); II: 2.09 (0.60, 0.36, 0.44, 0.39, 0.30); III: 1.86 (0.51, 0.29, 0.35, 0.35, 0.36); IV: 2.87 (0.74, 0.42, 0.68, 0.55, 0.48). Leg formula 4123. Leg spination: III—tibia v0-0-1p; metatarsus v0-0- 1p. IV—tibia v0-1p-1p; metatarsus v1p-1p- 1p. Palp: See description for the genus. Palp as in generic description ( Figs 41 View FIGURE 41 , 42 View FIGURE 42 A–C).

Female (Paratype). Coloration same as in male. Total length: 1.58. Carapace 0.74 long, 0.55 wide; Abdomen 0.82 long, 0.60 wide; Sternum 0.54 long, 0.44 wide; Spinnerets: ALS 0.12 long, 0.11 wide. Eye diameters: AME 0.04, ALE 0.03, PME 0.02, PLE 0.03; interdistances: AME–AME 0.04, PME–PME 0.02. Chelicerae 0.22 long. Leg measurements: I: 2.30 (0.64, 0.50, 0.50, 0.38, 0.28); II: 1.86 (0.52, 0.32, 0.39, 0.31, 0.32). Legs III and IV lost. Legs I and II with no spines. Vulva: copulatory ducts long, convoluted laterally and anteriorly from copulatory opening to secondary spermathecae; secondary spermathecae emerging as small lump; connecting duct thickened and almost straight (based on right side of vulva); primary spermathecae round; fertilization duct short, laterad ( Fig. 42E View FIGURE 42 ).

Remark. The genitalia of the only female specimen available was damaged and broken ( Figs 42 View FIGURE 42 D–E). However, what is left of the vulva clearly shows the reduced secondary spermathecae connected to the primary spermathecae by a thickened, wider connecting duct, which is diagnostic for this genus.

Variation. Total length (5 males): 1.72–1.95.

Distribution. Only known from the type locality in Mayombe, D.R. Congo ( Fig. 44 View FIGURE 44 ).
