Diagnosis. Distinguished from most other species of phyllicola  group (except C. bidayuh  , C. bankirai  , C. semengoh  ) by shape of appendix (widely curved with two ventral tines; Figs 47, 52View FIGURES 45 – 54; see also figs 170, 171 in Huber 2011), by male palpal tarsal organ on cylindrical process of tarsus (fig. 179 in Huber 2011), by serrated edge of embolus (figs 170, 173 in Huber 2011), and by drop-shaped pore plates ( Figs 49, 54View FIGURES 45 – 54; see also fig. 175 in Huber 2011); from closest known relatives ( C. bidayuh  , C. bankirai  , C. semengoh  ) by absence of split hairs dorsally on procursus; from C. semengoh  also by much shorter palpal segments and external female genitalia; from C. bankirai  also by tip of procursus (wide dorsal flap; Figs 45, 50View FIGURES 45 – 54); from C. bidayuh  also by absence of distal spine-like process on procursus. Females of C. bidayuh  and C. bankirai  lack the transversal sclerotized ridges on the epigynum of C. phyllicola  ( Figs 48, 53View FIGURES 45 – 54), and have the pore plates wider apart.

Variation. As noted previously ( Huber 2011), there is variation among males from different localities, especially with respect to the tip of the procursus ( Figs 45–46, 50–51View FIGURES 45 – 54). In males from eastern Borneo [type locality in East Kalimantan (Sepaku) and two further localities in East and South Kalimantan (Bukit Bankirai  , Loksado  )] the procursus dorsal flap is long and gradually narrowing towards distal ( Fig. 45View FIGURES 45 – 54; see also fig. 171 in Huber 2011). In all other males (central and western Borneo, Sumatra, Malay Peninsula) the dorsal flap does not reach the tip of the procursus and the ventro-distal apophysis is more distinct ( Fig. 50View FIGURES 45 – 54). The appendix in these males is slightly smaller but mostly identical in shape; in most of them, the subdistal tine on the appendix has a shallow depression (arrow in Fig. 52View FIGURES 45 – 54).

Within localities there is almost no detectable variation. Females are difficult to compare because most external genital structures (except some transversal folds) are pale whitish; internal structures are variably well visible through the cuticle, giving the impression of variation even within localities. Tibia 1 in newly examined specimens: 61 males: 6.0–8.9 (mean 7.92); 51 females: 5.4–7.5 (mean 6.62).

Natural history. At Kemensah, this species was abundant on palm leaves only. At Gunung Liang, a female with parasitized egg-sac was collected. Six of the eight eggs were parasitized (including the eggs closest to the female chelicerae; Fig. 15View FIGURES 13 – 19). At Bukit Barisan, webs were observed in detail and consisted of a relatively dense layer of silk very close to the leaf surface, not extending beyond the leaf. Egg-sacs contained between 8 and 12 eggs.

Distribution. Widely distributed in Southeast Asia ( Fig. 282View FIGURE 282), but note that all specimens other than those from East and South Kalimantan are assigned tentatively.
