MILLIPED GENUS DIXIORIA — HOFFMAN 17 



Relationships 



Generic : Dixioria is a member of the group of genera in which the 

 sternites are not strongly spined or lobed, the repugnatorial pores 

 open dorsolaterally through a distinct peritreme, the coxae of the 

 gonopods are without a long process, the prefemora are globosely 

 swollen and densely setose, and the telopodite is long, slender, and 

 unbranched, forming nearly a complete circle. This group also in- 

 cludes the genera Apheloria and Brachoria, of which the former is 

 obviously the closer relative. Both of these genera contain forms 

 which are distinctly broader in proportion to their length than are 

 the forms of Dixioria. Brachoria contains several species in which

the paranota are broadly rounded caudally as in Dixioria, and the 

 cyphopods of the two genera are similar. The males of Brachoria, 

 however, are singular in that the telopodite is interrupted at about it? 

 midlength by a distinct constriction or flexible articulation. The 

 gonopod of Apheloria differs chiefly in lacking subterminal processes 

 on the telopodite, here again the cyphopods are quite similar. In 

 none of the Aphelorias, however, are the caudal corners of the mid- 

 body paranota rounded off. 



SuBGENERic: As here conceived, Dixioria is composed of two 

 species, one of which is divisible into six geographic races. Both of
