METHODS 
Measurements. All measurements listed are in millimeters. When 
available ten specimens of each sex were measured. The purpose of 
this was to give some idea of the variation to be expected within a 
species population. Measurements are presented in tabular form to 
facilitate comparisons and aid in their use. 
Collection Records. Collection records for Mexico and Central 
America only are listed. Records north of Mexico are in earlier 
publications. Localities are listed geographically from north to south 
and from east to west. The number of specimens collected at each 
locality is indicated; the lower case “o” representing immature 
specimens. 
Drawings. Epigyna and palps were drawn after they were scraped 
free of hair and large setae removed. Internal genitalia of the 
female were drawn after clearing in clove oil.
