Figs 37 B–F, 39E–F, 40A–B, 43A–C

Type material. Female holotype from D.R. Congo, Langa-Langa , 02°28’N 21°27’E, 17 June 2009, D. De Bakker leg., deposited in MRAC 228139 . Two female paratypes deposited together with holotype .

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

Diagnosis. Females of Kituba langalanga sp. nov. differ from those of K. mayombensis sp. nov. by the epigyne with the epigynal plate not surpassing the epigastric furrow (surpassing the epigastric furrow in K. mayombensis sp. nov.) and copulatory openings rounded with C-shaped sclerotized margins (under small triangular hood-like ridges in K. mayombensis sp. nov.) ( Fig. 43A ). Males are unknown.

Description. Female (holotype). Carapace and legs yellow pale, abdomen slightly gray ( Fig. 37B ). Total length: 2.32. Carapace 0.80 long, 0.58 wide; Abdomen 1.50 long, 0.34 wide; Sternum 0.56 long, 0.46 wide; Spinnerets ALS 0.15 long, 0.13 wide. Eye diameters: AME 0.06, ALE 0.06, PME 0.04, PLE 0.06; interdistances: AME–AME 0.02, PME–PME 0.02. Chelicerae 0.29 long. Leg measurements: I: 2.36 (0.69, 0.50, 0.50, 0.40, 0.27); II: 1.77 (0.42, 0.30, 0.36, 0.35, 0.34); III: 1.66 (0.48, 0.25, 0.30, 0.34, 0.29); IV: 2.63 (0.70, 0.39, 0.60, 0.54, 0.40). Leg spination: III—tibia p0-1-0, v0-1p-1p; metatarsus p0-0-1. IV—tibia p0-0-1, r1-0-1, v1p-0-1; metatarsus v0-0- 1p. Vulva: copulatory ducts long, convoluted laterally and anteriorly; secondary spermathecae emerging as small bump; connecting duct thickened, moderately straight; primary spermathecae round; fertilization duct short, laterad ( Figs 43B, C ).

Male. Unknown.

Variation. Total length (3 females): 2.10–2.32.

Distribution. D.R. Congo, only known from the type locality ( Fig. 44 ).
