Hypothesis
What are the characteristics and distributions of two new species of Pterostichus in Idaho?
Conclusion
Two new species of Pterostichus have been identified, both of which are restricted to specific montane stream habitats in Idaho.
Supporting Evidence
- Both species are obligate ripicolous hygrophiles, found near small montane streams.
- Extensive surveys indicate their geographic ranges are highly localized.
- Additional undescribed species may exist in Idaho.
Takeaway
Scientists found two new types of beetles that live near streams in Idaho, and they are very special because they only live in certain places.
Methodology
Specimens were collected by hand along small streams in mountainous terrain and preserved in ethanol and vinegar.
Limitations
The geographic ranges of the new species are not fully known, and they may be highly localized.
