Fig. 9, Cephalothorax, rostrum and anterior part of abdomen. ^^^/i 



The cephalothorax (Fig. 9) widens posteriorly more than 

 in the other species; the anterior margin is slightly concave, 

 the posterior one is convex and the posterior angles are 

 concealed by the projecting angles of the abdomen. 



The small pseudocapitulum is constricted at the base and 

 for the greater part covered by the anterior edge of the 

 cephalothorax; it has no sense hairs. 



The two pairs of seyise hairs are shaped as in the other 

 species; the posterior pair is however placed further back- 

 wards.
