Length of leg segments: I 1.38 + 0.73 + 1.12 + 0.92 + 0.50 = 4.65; II 1.08 + 0.59 + 0.79 + 0.73 + 0.45 = 3.64; III 0.72 + 0.47 + 0.50 + 0.61 + 0.30 = 2.60; IV 1.15 + 0.57 + 0.91 + 0.98 + 0.40 = 4.01. Carapace deep yellow-brown, with faint grey mottling; surface finely wrinkled; fovea short, distinct, at ⅔ CL. AER slightly procurved, almost straight; clypeus height equal to approximately ½ AME diameter; AME and ALE subequal in size; AME separated by distance approximately ½ their diameter; AME separated from ALE by distance slightly less than ⅓ AME diameter; PER recurved, PME and PLE subequal; PME separated by distance approximately equal to their diameter; PME separated from PLE by distance equal to their diameter. Chelicerae deep yellow-brown, anterior surface covered with quite dense long, fine setae; promargin with three slightly separated teeth, retromargin with three adjacent teeth on common base; endites and labium orange. Sternum shield-shaped, yellow-brown, with orange-brown borders; surface finely wrinkled, covered with scattered short, fine setae. Abdomen elongate-oval, broadest in posterior half; creamy-yellow dorsally, with yellow dorsal scutum from ¼ AL to posterior; broad grey mottled stripe along midline, sides of abdomen also mottled grey, markings separated by pair of cream mediolateral strips; two pairs of distinct round sigilla, first and second pairs respectively just behind ¼ and ½ AL. Legs I to IV with yellow femora, remaining segments progressively darker to yellow-brown tarsi; cusps only present on metatarsi and tarsi I (Fig. 20 A View Figure 20 ).
