Diagnosis.
Females of Ablemma singalang can be distinguished from most congeners by the small rounded basal boss on the chelicerae (Fig. 30, arrow), and the elongated narrow inner plate of the internal genitalia (Fig. 33); short and triangular in other species. Furthermore, females are distinguished from A. malacca with similar internal genitalia, by the larger carapace tubercles (Fig. 31), smaller in the latter species (see Lin et al. 2017, fig. 7H).
Description.
Male. See Lethinen 1981: 48.
Female. Measurements: Total length: 1.14; carapace length: 0.48; carapace width: 0.41; abdomen length: 0.66; abdomen width: 0.60; clypeus height: 0.11. Length of legs: I 0.90 (0.29, 0.12, 0.23, 0.13, 0.13); II 0.78 (0.28, 0.13, 0.22, 0.15, 0.15); III 0.89 (0.26, 0.11, 0.20, 0.16, 0.16); IV 1.18 (0.36, 0.13, 0.30, 0.20, 0.19).
Carapace: Brownish orange; pars cephalica smooth dorsally, flat behind the ocular area than sloping upward with a fringe of 5 pits of which each bear a seta, and 3 small tubercles at apical end, reticulated laterally; pars thoracica finely reticulated, sloping straight down and then at an angle (Figs 28, 31); clypeus brownish yellow; sloping forward; short and smooth (Figs 30, 31). Sternum: Brownish orange; slightly wider than long, reticulated except medially (Fig. 29). Chelicerae: Yellowish orange; basal boss as a small rounded projection (Fig. 30, arrow); lamina well developed, translucent. Eyes: 6 eyes in compact group (Fig. 28). Abdomen: Dorsal scutum smooth, yellowish brown (Fig. 28). Laterally with 4 yellowish brown stripe-like plate, separated (Fig. 31). Ventrally covered by 4 smooth scuta; plumonary scutum brownish orange, with oval book-lung covers; postgenital scutum thin and straight, shorter than preanal scutum; preanal scutum large, rectangular, with dark and rounded posteromedial corner and 2 small posterolateral corners; anal scutum conical, short and curved (Fig. 32). Legs: Brownish orange, femora I–IV rugose ventrally. Genitalia: Inner plate long, distal end slightly bent; ducts narrow, transculent, connected to seminal receptacle; sac-like seminal receptacle with distinctly folded cuticle (Fig. 33).
Natural history.
Male and females specimens were collected together in secondary lowland rainforest, rainforest with rubber trees, and rubber plantation.
