The two sexes can readily be separated from the other members of the genus by the 
structure of the fifth 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 
bifureate prolongation. The distal end of the right side of the male genital segment is greatly 
produced. 
Candacia pachydactyla is widely distributed in tropical seas.
