The carapace is narrow, and in form almost a regular 

 hexagon ; the antero-lateral, the front, the postero-lateral 

 and the posterior borders being almost of equal length ; 

 it is very flat, smooth, or slightly lobular antero-laterally, 

 where it is thick and toothed. The front is wide, with a 

 wavy margin; the orbits are very open. The basal 

 antennal joint is widely joined to the front, and its 

 movable part is lodged in the internal orbital hiatus. The 

 fourth joint of the external maxillipedes is subrectangular 

 its antero-external angle is slightly prolonged, its antero- 

 internal angle is truncated for the insertion of the fifth 

 joint. The first pair of legs long, and in general smooth ; 

 the fourth joint exceeds by more than a half of its length 

 the border of the carapace. The walking legs are thin 

 and long, usually they have above a few hairs and 

 spines. 



The abdomen of the male is narrow, and composed of 

 five joints, the third, fourth, and fifth segment being 

 soldered together.
