Diagnosis. Distinguished from other species of vermiformis  group by tip of procursus (distal part and ventral flap of approximately same size, parallel and curved towards dorsal; Figs 188–189View FIGURES 188 – 203; see also figs 153, 154, 158 in Huber 2011) and by crescent-shaped pore plates ( Fig. 194View FIGURES 188 – 203; see also fig. 157 in Huber 2011); from most (except C. bugis  ) also by thin proximal part of bipartite cheliceral apophysis ( Fig. 192View FIGURES 188 – 203; see also fig. 161 in Huber 2011) and by strong and regular fringes at tip of embolus (figs 153, 160, 163 in Huber 2011); from several species also by narrow and distinct epigynal ‘knob’ ( Fig. 195View FIGURES 188 – 203).

Measurements and variation. Male from Lembah Anai  : palpal femur as in Fig. 191View FIGURES 188 – 203, distal process at 28% of femur length; palpal tibia length/diameter 0.55/0.33; bulb length 0.38; embolus length 0.50.

There seems to be no significant genitalic variation among specimens from different localities in this widely distributed species. Tibia 1 in 20 newly examined males: 6.2–7.5 (mean 6.9); in 19 females: 5.3–6.5 (mean 6.0).

Natural history. At Sikulikap Fall, most specimens were collected at one patch of large-leaved herbaceous plants close to the ground; webs were barely visible, consisting of only a few threads directly attached to the leaf surface; when disturbed the spiders did not vibrate but ran away (and eventually dropped to the ground). At most localities, this species occurs together with either C. phyllicola  or with C. anai  (or with both). Egg-sacs in this species are only moderately elongated ( Fig. 125View FIGURES 120 – 127).

Distribution. Widely distributed on the Malay Peninsula and on Sumatra, reaching into western Java ( Fig. 283View FIGURE 283). The specimens from Java (Cibodas; 1♂ 3♀ in RMNHAbout RMNH, ARA 17408View Materials) listed in Huber 2011 were re-examined for the present paper and their identification confirmed.
