Pselaphinae

Pselaphinae is a subfamily of beetles belonging to the family Staphylinidae, commonly known as rove beetles. These small, often cryptic insects are characterized by their greatly reduced antennae, which are typically clubbed and have only a few segments. They also possess distinctively shaped heads, often with prominent palpi. Pselaphinae are predominantly found in leaf litter, soil, and decaying wood, and some species inhabit ant or termite nests, where they exhibit myrmecophily or termitophily, respectively. Their diet varies, with many species being predatory on small invertebrates such as mites, springtails, and insect larvae.

The subfamily is diverse, with numerous genera and species distributed worldwide. Due to their small size and secretive habits, they are often overlooked, and many species remain undescribed. Research on Pselaphinae focuses on their taxonomy, evolutionary relationships, and ecological roles. Their association with social insects has provided insights into the evolution of symbiotic relationships. Despite their small size, these beetles play a role in the decomposition process and nutrient cycling within their microhabitats.
