 pitch}', the middle legs blackish, with the lower half of 

 the femora yellowish. Hind legs black. 



In the male the 6th segment is, on the underside, a little 

 emarginate in the middle; the 7th with a rather deep and 

 narrow notch, on each side of which the hind margin is

 Peru in my collection, which I believe is conspecific with 

 the Amazonian individuals.
