The two sexes can readily be separated from the other members of the genus by the 

 structure of the rïfth pairs of feet. The genital segment of the female has two large ventrally 

 directed spines. The right side of the last thoracic segment of the male terminates in a slightly 

 biiurcate prolongation. The distal end of the right side of the male genital segment is greatly 

 produced. 



Candacia pacJiydactyla is widely distributed in tropical seas.
