irregular furrows. Ocular tubercle and anterior half of cephalothorax 

 densely covered with reddish granules (abbreviated spinules). 

 Upper lobe of rostrum as long as the lower lobes. 



In Hexisopus the 3 distal segments of the fourth leg are terete or 

 only slightly compressed and without angular edges, the tibia is 

 much longer than wide and subequal in length to the 2 distal 

 segments together, the metatarsus is narrower than the tibia and the 

 tarsus narrower than the metatarsus, each of them being also longer 

 than wide. The tibia of the third leg is terete and much slenderer 

 than the femur. The pedipalps are not spined, the inner surface of 

 the chelicerae is provided with a number of parallel stridulating 

 ribs, and the upper lobe of the rostrum is much shorter than the 

 lower lobe.
