Sympastrophus, gen. nov. 



This genus is undoubtedly close to Spirostrophus with which it 

 agrees, while difTering from Trigoniulus, in lacking pads on the tarsi 

 of the anterior feet of the males. It is segregated from Spirostrophus 

 on the basis of differences in the male gonopods. The median plate 

 of the gonopods is distally deeply incised. The anterior gonopods are 

 especially characterized by having the femur extended into a con- 

 spicuous process on the mesal side of a distinctly separated terminal 

 joint, this process curving ectad. In the posterior gonopods below 

 the ordinary processes there is a straight slender styliform process 

 that seems to convey the seminal duct, though this is not wholly 

 certain.
