While a number of species of Auximus have been described from 

 Ecuador, only one was previously known from Peru, A. funestus 

 (Keys.), a species differing rather widely from the present one in hav- 

 ing its posterior row of eyes straight, in the sparser spining of legs, 

 in the different form of epigynum as well as in color.
