Carapax rather strongly tubereulate. stout, greatest breadth hardly 

 great as length excluding beak; beak at tip eliminate; posterior 

 lateral tooth subacute, the two others bilobate ; medial region with 

 three small tubercles posteriorly, arranged triangularly; post-medial

 margin of carapax not tubereulate or bearing a prominence. Abdomen 

 of male very narrow, towards base suhorbieular, Fingers of hand a little 

 apart at base; the lower of fi tiuth . denticulate along its whole inner 

 margin, the upper near base bare in f nttth\ but having a bioad tooth
