Phlaeopterus
Phlaeopterus is a genus of omaliine rove beetles containing 22 species distributed across northwestern North America and eastern Asia. The genus exhibits notable evolutionary transitions in body size, with two independent origins of large-bodied adults (exceeding 5 mm) from a small-bodied common ancestor. Large-bodied species are exclusively associated with alpine snowfield habitats, though statistical support for this correlation remains unconfirmed. The genus is monophyletic based on combined molecular and morphological phylogenetic analyses.
