sp. nov. males lack an apical pile brush on the profemur and have an unmodified metatibia. The proximal ventral section of the profemur has 3-4 long black pile and the metafemur is covered with long, thin yellow pile and some shorter and thicker black pile on the ventral side, except on the extreme distal end where the black and yellow pile is equally long. The pair of maculae on tergite II are very large and rounded. The species resembles
