 inal segment with dense row of marginals; genital 

 segment red, white-pruinose below, the orifice slit- 

 like, two spiracles in each lateral sclerite, the outer 

 separated by more than its own width from the mar- 

 gin (in other species one of them is generally at the 

 outer edge of the sclerite if visible at all) ; legs not 

 villous, middle tibia with two bristles on outer side. 

 Otherwise as in male.
