Notodesmus, gen. now 



Differing from Antichiropus and closely related genera in the char- 

 acter of the male gonopods. Readily distinguished from the same 

 in wholly lacking spines or processes at the end of the long tibial or 

 proximal division of the telopodite; the distal division of the telopodite 

 consisting of a straight proximal subdivision at the dorsodistal edge 

 of which there is (at least in the genotype) a thin short spine, and a 

 strongly curled, thin distal blade which in the genotype crosses or 

 interlocks with that of the other gonopod. The first legs as in related 

 genera stout, with the third joint provided with a tooth at proximal 

 end on ventral surface but not so strongly modified as in Antichiropus. 

 Fifth sternite with anterior edge bearing the usual plate-like elevation 

 but this low and thick in the genotype. Antennae of moderate length, 

 distally clavate; second, third, and fourth articles subequal and but 

 little longer than the fifth and sixth. Keels but slightly raised above
