MALE (n=3): length=1.12, 1.44, 1.48; radicle, A1 and A2 yellow, coxa A3–A12 bright brown; (FCI =1.21); HW/IOS =1.41, 1.47, 1.53; HW/TSL =1.32, 1.28, 1.33; OOL longer (POL/OOL =1.47, 1.40, 1.50; OOL/LOL =1.54, 1.53, 1.57); A1/r =2.85, 2.80, 3.00; A2–A6 unibottled, A5 modified; A7–A11 double bottled, with distinct constrictions; flagellomeres with numerous ventral microcilia; A8 7, 7, 7.5 times as long as wide; TSL/ML =1.48, 1.42, 1.47; posterior row of foveae of mesopleural carina reduced, maximal distance between posterior row of foveae of mesopleural carina and mesepimeral sulcus 4–5 times as long as posterior row of foveae of mesopleural carina; m/st =2.90, 3.10, 3.10; HWW/HWS =2.30, 2.68, 2.73; metasoma elongate (T1W/T1+T2L =1.50, 1,54, 1.55); T3W/TSL =0.96, 0.96, 0.97; T3 costae reduced, shortened laterally and medially;

Diagnosis. Most similar to X. comatus , distinguished by the sparse, thin setae of body, smooth frons, presence of frontal patch, presence of netrion sulcus, absence of rugulous sculpture on T3.

Etymology. From the latin aureus, meaning golden and the latin pes, meaning leg, referring to pale yellow color of legs.
