Legs light yellow-brown, coxae of all legs with dark spot, fore and middle femora with brown stripe dorsally and ivory spot on the underside apically, hind femur red with dorsal brown stripe, hind tibia with ivory on the upper side.

Morphology. Head with very fine microsculpture. Scutum, scutellum and lateral parts of propodeum smooth and shiny, without remarkable microsculpture. Propodeal enclosure finely reticulated, with distinct oblique striae (fig. 16). Body without long erect setae. Inner orbits, hind margin of pronotum, anterior part of mesopleuron, lateral parts of propodeum, of fore femur and outside of mid, hind coxa and lateral hind parts of terga II‒III with appressed silver pubescence.
