The anterior median eyes are twice as large as the anterior laterals and the same size as th e posterior laterals; and are closer to each other than to the laterals. The clypeus height equals the diameter of an anterior median eye . Lower margin of the furrow of the chelicerae with three, almost equally spaced teeth, the median tooth the largest, the othe r two similar in size . Legs 4123, unbanded. Tibia I with twelve long, overlapping ventrolateral, two pro -lateral, and retrolateral spines . Metatarsus I with nine ventrolateral and lateral spines, the distal pair far removed from the apical position . Tibia II with 12 long overlapping, ventrolateral, two prolateral, and two retrolateral spines. Metatarsus II with nine ventrolateral and lateral spines .
