Setre, save an odd one here and there, are invisible. 



Clitellnra strongly marked, saddle-shaped, incomplete 

 ventrally, except in the middle of segments IG and 17, 

 extending over segments 14-17. 



Male pores on very prominent papillae on segment 18. 



Oviduct pores placed on a ridge which runs across the 

 anterior part of segment 14>. 



Spermathecal pores, five pairs, between segments 4 and 5, 

 5 and C, 6 and 7, 7 and 8, 8 and 9. 



Dorsal pores present, the first between segments 3 and 4.
