with strong bristles at each joint. The claws are large, and the 

 cleft at the distal end of each leg into which they sink when at 

 rest is large and pointed at its junction with the claws. The 

 legs of the fourth pair are longer and slighter, but the joints are 

 well protected by strong bristles similar in structure to those 

 we find on the other legs. The palpus is strong, and, as usual, 

 composed of five segments. The width of the palpus is about 

 the same as the second segment of the first pair of legs. On the

penultimate segment of the palpus is a chitinous peg near the 

 fifth segment, and behind that on the flexor edge are two very 

 small papillae with setae. 



The dorsal surface is quite smooth without any plates. The 

 ventral surface is nearly two-thirds covered with the epimera, 

 which are pushed up close together as shown in the drawing. 

 The genital cleft is long, with a tongue-shaped plate on each side. 

 Each plate has ten acetabula. 



Only one female was taken. I propose to name this species
