( Fig. 99 a-e)

Description: Female: Total length 5.85 mm. Cephalothorax 2.20 mm long, 1.90 mm wide, 1.40 mm high. Abdomen 3.65 mm long, 1.80 mm wide, 2.35 mm high. Cephalothorax chocolate-brown with a broad leaf-like or inverted umbrella-like band in the middle, eight yellow spots in the lateral margins (four on each side),and black eyes margins. Cephalic moderately attenuate and lateral sides almost parallel. Anterior part of the yellow band extended between PME. Thoracic area distinctly globular with a short black longitudinal fovea and a slightly cleft midposterior end. Eight eyes, all clear, in two rows, slightly recurved to straight, AE shorter than the procurved PE. Eye diameter (mm): AME = 0.20, ALE = PLE = PME = 0.15. Eye separation: AME-AME one half eye diameter, AME-ALE one fifth ALE or 0.15 AME diameter, PME-PME as long as one eye diameter, PME-PLE one half AME diameter. Median ocular quadrangle almost a square, front very slightly longer than behind, posterior width and length equal. Clypeus height small, 0.75 times AME diameter. Sternum yellow with yellow-brown hairs and brown margins, wider than long, with truncate anterior end and shortly pointed posterior end between coxae IV. Labium wider than long, brown with yellow distal end, subbasal area groove transverse. Maxillae same color as labium, longer than wide, outer lateral margins without indentions for the reception of pedipalps, inner lateral margins with a cavity, distal end with two or three thick sets of blackish yellow scopulae on a yellow base. Chelicerae moderately small and robust, attenuate apically, slightly swollen frontomedially, with a small boss. Promargin bears two teeth and scopulae anterior to the teeth and entire length of attenuation. Retromargin with five small teeth. Legs moderately long and slender, yellowish brown except dark brown to black femora I and II and apical one half of femora III and IV, black patches in patellae and posterior and subapical areas of tibiae I and 11. Spination in femora I = 4-0-3-0, II = 3-0-2-0, III = 3-0-2-2, IV = 3-0-0-1, tibiae I = 0-16-0-0, II = 0-12-0-0, III = 0-15-1/2-2, IV = 0-4/5-2-2; metatarsi I = 04-0-0, II = 0-6-0-0,111 = 0-5-0-1, IV = 0-5-2-2. Metatarsus I/tarsus I = 1.16. Tarsi two-clawed, each superior claw with five to seven teeth, claw tuft distinct and plumose apically. Leg formula 4132. Pedipalp yellow-brown with blackish femora, spination in femora = 2-5-1-0, patellae = 1-0-2-0, tibiae = 2-5-2-0, and tarsi = 0-1-1-0, singleclawed with ten teeth.

Abdomen elongate, yellow with irregular black to gray flecks and broad black to gray bands on each side of the cardiac area. Venter of abdomen with a W-shaped brownish gray band from epigastric furrow to the sclerotized posterior spiracle. Epigynum moderately bulbous, reddish brown with yellow margins, narrow and deep posterior cleft and shallow anterior notch. Spinnerets visible dorsally, all segment II yellow in all pairs, anterior pair wide basally and slightly separated from each other, posterior pair more wide apart and cylindrical.
