margins of cephalic and median tibiae armed with five to six 

 (normally six) well spaced spines. Male subgenital plate with 

 distal margin more or less decidedly truncate, with no decided 

 emargination or production; small, slender, filiform styles present 

 disto-laterad. 



The difference in number of caudal tibial spurs separates this 

 subgenus from the subgenus Xiphidion Serville. 



Of the material here studied, the species modestus (Redtenbacher) 

 and javanicus (Redtenbacher) alone belong to the present subgenus.

This is a very plain species. The dorso-internal node on the 

 male cercus, proximad of the heavy median spine, serves readily 

 to distinguish this sex of affinis from the males of the other species 

 here recorded. 



The ventro-external margins only of the caudal femora are armed, 

 with the following number of spines in the present pair; cf 2 and 3, 

 9 2 and 3. 



Length of body c? 13, 9 13.7; length of pronotum tf 1 2.8, 9 3; 

 length of tegmen d 1 15.9, 9 15; length of caudal femur cf 12,
