Seven species of Chelifer have been found in the United 

 States. These can be separated by the following table which is 

 based on one published by Banks C95&):

 side. This is a cave species, described from Kentucky 

 and Virginia. Cheli f er mirabilis 



AA. With two distinct eyes. 



B. Tibia of the pedipalp a little convex on the inner side; 



fingers a little shorter than the hand. This is a western 



species which has been found in Utah, California, and 



Oregon. Chelifer scabrisculus 



BB. Tibia of the pedipalp not convex on the inner side; 



fingers as long as the hand. 



C. Hand much darker than the other part of the palpus. 



Common in the East and the Middle West. 



Chelifer muricatus 

 CC. Palpi unicolorous. 



D. Tibia of the pedipalp longer than the cephalothorax 

 plus the chelicerae and distinctly concave on the 

 outer side at the base. Known only from south- 

 ern Florida. Chelifer floridanus 

 DD. The tibia of the pedipalp not longer than the ceph-
