Diagnosis. No oblique ridge on inner surface of palm. Carapace 

 broad behind. Ambulatory legs narrow. 



Description. Carapace very convex, smooth, less uneven than in 

 U. pugnax. Front more than one-third of fronto-orbital width, 

 broadly rounded below. Eyebrow deeper than in U. pugnax, its 

 lower part visible in dorsal view. Upper margin of orbit slightly 

 sinuous; antero-lateral angle little prominent. Lateral margin 

 strongly curved outward behind the orbit. 



Large cheliped of male shaped much as in U. pugnax, although 

 the fingers do not attain so great a length. A ridge runs along the 

 pollex from the tip backward a slight distance upon the palm. The 

 largest prehensile tubercles are just behind the middle of the pollex 

 and near the tip. Inner surface of palm granulate, the granules 

 coarser on the thickest part of the palm ; no oblique ridge across the 

 middle.
