Colouration: carapace dark brown to black; femora darkened; sternum, chelicerae, endites and labium similar in colour to carapace (Fig. 23). Carapace: smooth in texture; fovea absent; decorated with squamose setae; posterior margin truncating; anterior margin narrowing slightly from coxa I; PER procurved in dorsal view, AER recurved in anterior view. Chelicerae: decorated with plumose setae. Labium: triangular in shape; tuft of setae present at tip. Endites: oblique; cluster of setae present on inner–apical margin. Sternum: shield-like, broadest at coxa II; posterior margin tapered to point between coxa IV. Legs: femora laterally flattened, highest at base, leg I more pronounced in this fashion; rest of legs normal, thin; decorated with lanceolate setae (Fig. 68). Leg macrosetae: Palps: 1do, 1pl, 1do, 1pl, 1pl, 1plv, 3vt. Leg I: 1do, 1pl. II: 1d. III: 1do, 1pl, 1rl, 1plv, 1vt, 1pl, 1rl, 1plv, 1rlv, 4vt. IV: 1do, 1pl, 1rl, 2plv, 2vt, 1plv, 4vt. Legs I–IV with two rows of scopulate setae on metatarsi and four rows on tarsi. Abdomen: cylindrical in shape; decorated with squamose setae; dorsal pattern not visible; venter similar in colour to dorsum; sigilla not visible. Palp: retrolateral tibial apophysis present subapically on dorsal margin, small; median apophysis present medially, elongate, curved at tip; sperm duct present on retrolateral surface of tegulum, curved at base of tegulum; embolus broadest at base, tip thin and elongate, skewed retrolaterally; cymbium widest at midline; tapering slightly towards apex and round at tip, two small spines present on tip of cymbium, three ventral terminal spines present in front of embolus (Figs 142, 143).
