Type material. Holotype male and paratype female, CHINA: Guangxi, Nanning City (22.8 °N, 108.3 °E), 2. November 1983, Joachim Haupt leg. ( IZCAS)

Etymology. The specific name is derived from the compound word with the Latin adjective capax and the Latin noun limbus, meaning “capacious” and “fringe” respectively, and referring to the capacious fringe on cymbial furrow; noun in apposition.

Diagnosis. This new species can be easily recognized from all other Coelotinae by the broad patellar apophysis, the broad, anteriorly extended cymbial furrow, and the unique embolus in male and by the broad but shallow atrium, the widely separated epigynal teeth, and the laterally originated, anteriorly extended and spiral copulatory ducts in female.

Description. Male. Holotype total length 4.2, prosoma 2.4 long, 1.9 wide; opisthosoma 1.8 long, 1.3 wide. Eye measurements: AME 0.08; ALE 0.12; PME 0.10; PLE 0.10; AME –AME 0.05; AME –ALE 0.03; ALE –PLE 0.05; PME –PME 0.05; PME –PLE 0.08. Clypeus 0.18. Chelicerae with 3 promarginal teeth and 4 retromarginal ( Fig. 1View FIGURES 1 – 7). Leg IV longest; leg formula: IV, I, II, III; the measurement of legs is as follows: I: 9.2 (2.4 + 2.9 + 2.4 + 1.5); II: 8.4 (2.2 + 2.7 + 2.2 + 1.3); III: 7.6 (2.1 + 2.4 + 2.0 + 1.1); IV: 9.6 (2.5 + 3.0 + 2.7 + 1.4).

Patellar apophysis broad, with the top almost reaching the distal end of tibia; RTA with distal end not extending beyond tibia; lateral tibial apophysis distinct; cymbial furrow longer than half cymbial length, with broad margin and the distal end widely separated from the cymbium; conductor simple, with small dorsal apophysis; median apophysis small, spoon –shaped; embolus long, with strong base, and abruptly becoming slender at the basal one third ( Figs 2 –5View FIGURES 1 – 7, 20– 22View FIGURES 20 – 24).

Female. Total length 4.7. Prosoma 2.2 long, 1.6 wide; opisthosoma 2.5 long, 1.6 wide. Eye measurements: AME 0.09; ALE 0.13; PME 0.10; PLE 0.13; AME –AME 0.05; AME –ALE 0.05; ALE –PLE 0.05; PME –PME 0.13; PME –PLE 0.10. Clypeus 0.15. Chelicerae with 3 promarginal teeth and 3 or 4 retromarginal. Leg IV longest; leg formula: IV, I, II, III; the measurement of legs is as follows: I: 7.3 (2.0 + 2.5 + 1.7 + 1.1); II: 6.6 (1.9 + 2.2 + 1.5 + 1.0); III: 6.0 (1.7 + 2.0 + 1.5 + 0.8); IV: 7.5 (1.9 + 2.4 + 2.1 + 1.1).

Epigynal teeth short, situated anteriorly close to anterior atrial margin and separated, by slightly less than atrial width; atrium broad, shallow; copulatory ducts large, originated laterally, extended and spiraled anteriorly with 3–4 loops; spermathecae slightly separated from each other; spermathecal head small ( Figs 6 –7View FIGURES 1 – 7, 23– 24View FIGURES 20 – 24).

Distribution. China (Guangxi) ( Fig. 34View FIGURE 34).
