Table 1. Measurements and indices of Pogonomyrmex mayri females and 
workers. Data for the first female specimen are listed first, followed by those of the 
second. Worker data are ranges from 6 individuals selected to include the largest and 
smallest available from 7 collections. Measurements are expressed in millimeters; 
indices in percentages, and both follow the standard definitions (see Brown, 1953: 
11-14; 1975: 3-4). Head width was measured just behind the eyes. Postpetiolar and 
gaster measurements were taken separately, and from dorsal view.
