Discussion: The males are most similar to those of hilli by the 
form and development of the right paramere. Newtoni is easily 
separated from hilli by spurred mesotrochanters, long spatulate to 
pedunculate mesotibial spurs, and symmetrical penis apex. 
Etymology: Named for A. F. Newton, Jr., who has collected 
many interesting Pselaphidae in Australia.
