The slightly increased COI variation of this species (2.3%) is expected for specimens separated by great geographic distance. For example, the specimens from Pennsylvania are 0-1.3% different from each other and the specimens from Saskatchewan are 0.3% different from each other, but Pennsylvania specimens are 1.3-2.0% different from the Saskatchewan specimens. However, even specimens from New Mexico are only 2.0-2.3% different from other localities, despite being separated by great geographic distance and ecoregions that act as barriers for other

|
(i.e., the Great Plains). This variation in COI in the New Mexico samples supports two hypotheses: 1) given the relatively low divergence of approximately 2%, New Mexico specimens represent the same species as specimens further east; and conversely, 2) given the relatively high divergence of greater than 1%, New Mexico specimens represent a long-standing population, not a recent introduction from the east.

<paragraph pageId="0" pageNumber="1">This species hypothesis is supported by low COI divergence within the species (0-2.3%) (but see above discussion) and high divergence between species (3-15%), and by the morphological characters outlined in the diagnosis.</paragraph>
