dozen stout bristles in a row behind; forceps red, the 

 apical part shining black; viewed from behind they 

 are not at all divergent, the free part is narrower at 

 the base, widening with an angle on the outer side; 

 the apices sharp and close together. In profile the 

 free part bends back considerably to the point of an- 

 gulation behind, then slightly forward to the apex; 

 just back of the extreme tip but not extending to the 

 hind angle there is a striking tuft of small black erect 

 hairs; accessory plate yellow, large, triangular, with 

 angles rounded; posterior clasper reddish, the tip 

 blackened, rather straight, not much hooked; an-

 curved forward but not very long, rather flat at apex ; 

 penis one- jointed, reddish brown, the back plate mod- 

 erately grooved along its middle, and near the base

 an angle toward the apex, its sides developed into a 

 thin and somewhat rolled-up margin; its apical part 

 forming two widely divergent black lobes; fifth ster- 

 nite very inconspicuous, not diverging and not pro- 

 vided with noticeable hairs.
