Oreoneta
A genus of dwarf spiders (family Linyphiidae) established in 1894, comprising approximately 30 species distributed across cold-temperate and Arctic regions of the Northern Hemisphere. Most species inhabit high-latitude or high-altitude environments. The genus was revised extensively by Saaristo & Marusik in 2004, resulting in numerous new species descriptions.

Pentodontini
rhinoceros beetles
Pentodontini is the most diverse tribe within the subfamily Dynastinae (rhinoceros beetles), containing over 100 genera distributed across multiple biogeographic regions. Most genera are restricted to a single biogeographic region. The tribe is characterized by substantial morphological diversity, with generic-level identification often relying on mouthpart morphology in females and secondary sexual characters (horns, claw modifications, antennal club length) in males.
