Etymology. The species is named after the type locality.

Diagnosis. C. lukiense sp. nov. is most similar to C. kupensis Lotz, 2007 , both having large spermathecae and an anterior pocket in the epigynal depression (see Lotz, 2007b: figs 36–37), but differ by the shorter copulatory ducts ( Figs 29–30 View FIGURES 22 – 30. 22 – 27 C ).

Description. Female: (n = 7): TL = 10.40 (8.1–12.1); CL = 4.11 (2.9–5.0); CW = 3.09 (2.3–3.5); OAL = 0.62 (0.45–0.80); OAW = 1.81 (1.3–2.3); CLL = 0.08 (0.05–0.10). Chelicerae: robust with long fangs; fang furrow with six teeth of unequal size, PMT:RMT = 3:3 ( Fig. 28 View FIGURES 22 – 30. 22 – 27 C ). Measurements: AME–AME 0.30; AME–ALE 0.40; AME diameter 0.25; PME–PME 0.55; PME–PLE 0.60; PME diameter 0.25; MOQAW 0.85; MOQPW 1.00; CI (CL/ CW) 1.43; LL:CL 5.08; STL 2.40; STW 2.10. Leg measurements: I—6.5+2.1+6.7+7.4+2.7 = 25.4; II— 4.5+1.9+4.1+4.6+1.5 = 16.6; III—3.5+1.6+2.7+3.6+1.2 = 12.6; IV—5.0+1.9+4.2+5.4+1.5 = 18.0; Palp— 2.0+0.7+1.0+1.9 = 5.6. I 0-1p-1p, 0- 1 v-0, 2v- 1v-1v; II 0-1p-1p, 0- 1 v1p-0, 2v- 2v-1v; III 0-1p1r-1p1r, 0-1p1r-0, 2v 1p1r- 2v 1p1r- 3v 1p1r; IV 0-1p1r-1p, 0-1r-0, 2v-2 v1 p1r- 3v 1p1r. Abdomen: creamy-yellow with a faint heartmark. Epigynum ( Figs 29–30 View FIGURES 22 – 30. 22 – 27 C ): depression wider than long with a slight pocket anteriorly; copulatory openings situated posteriorly in depression; internally, copulatory ducts proceed anterio-laterally, curving medially before ending anteriorly in large bean-shaped spermathecae; fertilization tubes enter spermathecae posterior-medially.

Male: unknown.

Distribution. Known from several localities in east, west and southern D.R. Congo ( Fig. 54 View FIGURES 52 – 55 ).

Habitat. Rainforest.
