Anterior fringe of orange and white hairs present ( Fig. 15 ). Thorax with indistinct light brown lines radiating from fovea. Clypeus brown, much narrower (17%) than AME diameter, covered with long, white hairs. Chelicerae brown, slender with papillate anterior surface and frontal spur; fangs with distinctive protrusion ( Fig. 16 ). Promargin with single tooth, retromarginal tooth with 4–5 cusps. Endites brown, with lateral outgrowth ( Fig. 16 ). Labium brown. Sternum light brown. Palps light brown. Tibia short, light brown. RTA short, slightly hooked ( Fig. 18 ). Tegulum much longer than wide. Embolus thin and long, set prolaterally (at 8 o ′clock). Legs I brown, ventral spination: pI: 2, tI: 2-2-2 (prolateral 1), mI: 2-2. Legs II lightbrown; ventral spination: pII: 0, tII: 2-2-2 (prolateral 1-1), mII: 2-2. Other legs light brown. Abdomen brown with longitudinal whitish stripes along the sides and the middle.
