Hypothesis
Is Trichocnemis a distinct genus separate from Ergates and Callergates?
Conclusion
Trichocnemis and Ergates are distinct genera, supported by shared characters in North American Trichocnemis species.
Supporting Evidence
- Trichocnemis has not been recognized as a separate genus in North America since 1962.
- Two species of Trichocnemis are recognized: Trichocnemis spiculatus and Trichocnemis pauper.
- Trichocnemis species share distinct characters not present in Ergates or Callergates.
Takeaway
This study looks at a group of beetles and shows that one type, Trichocnemis, is different from two others, Ergates and Callergates.
Methodology
External morphology of male and female specimens was examined, along with male genitalia of one species from each genus.
