Integrative taxonomy

Morphological differences between the two identified morphotypes of C. vernale (A and B sensu Nedeljković, 2011) were small and further analyses were required to test whether they were separate taxa. To find additional differences between morphotypes A (typical C. vernale) and B (C. montanum sp. nov.), DNA, the morphometry of wings and surstyli, and ecological niches were analysed.
