Table 3. Summary of the ecological interchangeability (EI) criterion for cohesion species delimitation between populations of the A. unicolor species complex. We evaluated a proxy for ecological interchangeability by measuring the overlap between ENMs for the sister lineages comparisons as well as taking into account previous morphological and behavioral criteria for distinguishing A. microunicolor. Na and Nb values are the number of occurrence records for the first and second lineages used in a comparison, respectively. Niche identity to refers to the ”niche equivalency test”, and niche similarity refers to the ”niche similarity (i.e. background) test” proposed by Warren et al. (2008) (see Methods for details). a ENMs are no more similar or different than expected by chance; b ENMs are more similar than expected by chance for one comparison, yet ENMs are more different than expected by chance for the reciprocal comparison; see Discussion.
