To this species I ref er — not without hesitation — a 

 single adult male from Tatarenda in Bolivia. In the struc- 

 tare of pedipalp and other parts of the body it seems to by 

 highly agreeing, but the colour is somewhat different. The 

 cephalothorax is yellow testaceous, only in the region of 

 eyes it is a little rufescent. On each side of the cephalo- 

 thorax a more or less distinct blackish band. Mouth-parts, 

 sternum and coxae påle testaceous. Legs of the same colour 

 but with blackish rings a t the ends of the tibial joint and 

 the two distal joints more or less rufous. Perhaps the speci- 

 men has just undertaken the last moulting.

 some small, unimportant details differs from that published 

 by Keyserling Hand olmberg.
