Key Identification Features
- has several distinctive morphological identification features, though these features vary considerably both within single populations and across different geographical regions.
- Morphological features that were previously used to separate P.
- More recent molecular studies have identified cryptic species: genetically distinct lineages that cannot be reliably distinguished through morphological examination alone.
- Its genetic makeup shows distinct geographical structuring, with European and North American populations forming separate sister clades.
