Paratypes: 1♂ 1♀ (UBCZ; KYU-SAL304), SINGAPORE: Bukit Timah Nature Reserve, 1.3573 –1.3575 °N, 103.7751– 103.7759°E, 100–130 m elev., 5 June 2019, leg. W.P. Maddison & K. Marathe, WPM#19-038.
Etymology. The specific epithet is a noun in apposition referring to the type locality.
Diagnosis. Males resemble C. asper sp. nov. in the shape of the palp, but differ from it by the less-developed denticles on the embolic base, the relatively smooth and flat surface of the embolic disc, and the longer retrolateral tibial apophysis (Figs 36–41). The female can be distinguished from that of C. asper sp. nov. by the trajectory of the copulatory ducts and the wider EW compared with the width of the vulvae (Figs 42–46).
Description. Male. Habitus as shown in Figs 30, 32. Carapace length 1.40; abdomen length 1.14. Measurements of eyes: AME 0.29, ALE 0.17, PME 0.05, PLE 0.16. Measurements of legs: I 2.37 (0.74, 0.49, 0.52, 0.33, 0.29), II 1.98 (0.65, 0.33, 0.42, 0.31, 0.27), III 2.01 (0.65, 0.28, 0.41, 0.39, 0.28), IV 1.90 (0.61, 0.18, 0.41, 0.43, 0.27). Chelicerae with fang-like projection distally; promargin with two teeth, retromargin with one bicuspid tooth. Palp (Figs 36–41): embolus coiled for more than a circle; embolic disc large, weakly sclerotized, centrally concave; LED narrow, serrulate-edged; tegulum not obviously sclerotized, tegular lobe present; retrolateral tibial apophysis slightly curved, wide at base and gradually tapered towards tip in retrolateral view, with distal part slightly innerhooked in ventral view. Sternum without setal tuft. Color in alcohol (Figs 30, 32): carapace reddish brown, cephalon slightly darker, CPSB present, dorsal abdomen pale yellow, with greenish brown markings, not obviously sclerotized; ventral abdomen grayish brown; legs I–II slightly darker than legs III–IV.
Female. Habitus as shown in Fig. 31. Carapace length 1.41; abdomen length 1.31. Chelicerae (Fig. 35) as in males but without fang-like projection. Measurements of eyes: AME 0.35, ALE 0.20, PME 0.05, PLE 0.18. Measurements of legs: I 2.24 (0.74, 0.41, 0.53, 0.36, 0.20), II 1.97 (0.63, 0.38, 0.43, 0.28, 0.25), III 2.12 (0.72, 0.30, 0.38, 0.42, 0.30), IV 2.37 (0.82, 0.30, 0.51, 0.45, 0.29). Color in alcohol (Fig. 31) as in male. Sternum as in male. Epigynum (Figs 42, 43, 45): window large, with sclerotized rims, median septum absent; lateral depressions shallow. Vulva (Figs 44, 46): CD long and coiled, swerving for nine times; AG small and oval, almost extending anteriorly; spermathecae slightly bulging, peanut-like.
