 correspond in position with the most dorsal setae. 



Reproductive system. Two pairs testes in segments 10 and 

 11, into which the ciliated rosettes open. 



Spermiducal glands, coiled, tubular, in segments 18 and 19.

 9 and the anterior of segment 12. 



Ovaries in segment 13, into which the oviducts open. 



Spermathecae, five pairs, in segments 5-9, each consisting of a
