 and 4 and an indistinct median dorsal vitta shining black, the heavy pollen 

 confined mostly to sides of abdomen and to a narrow basal margin or 

 entirely absent in median dorsal area of segments 2, 3, and 4 in various 

 lights. Palpus brownish black to black ; midtibia more bristly, especially 

 in female, with three or more easily noted median anterolateral bristles, 

 usually two bristles above longest middle one; midtibia with one long 

 and one shorter inner ventral bristle, the shorter one often approaching 

 or in vicinity of half the length of the longer; hind tibia with uneven 

 bristles; sometimes fourth segment almost wholly shining black; sides 

 of female abdomen black or only slightly red
