Edaphus

Edaphus species are distinguished within Euaesthetinae by genitalic and external morphological characters detailed in species-level keys. The Korean fauna can be identified using the key provided in Puthz (2022), which separates six species based on male genitalia, body proportions, and punctation patterns. Specimens are small-bodied rove beetles with the characteristic abbreviated elytra of Staphylinidae.

Forest leaf litter and soil; deadwood debris; bamboo forest litter; riparian zones near streams and waterfalls; fungal fruiting bodies and plant root zones; pine needle and herbaceous debris.

Cosmopolitan: documented from Palaearctic, Oriental, Afrotropical, Australian, Nearctic, Neotropical, and Pacific regions. Specific records include South Korea (provinces: Jeonnam, Jeonbuk, Chungbuk, Chungnam, Daejeon, Gyeonggi, Gangwon, Gyeongbuk, Gyeongnam, Jeju, Ulsan), Denmark, Norway, and Sweden.

Specimens have been collected using sifting of leaf litter and soil, mushroom window traps, flight intercept traps, and Lindgren funnels, indicating ground-dwelling habits with potential dispersal by flight.

Edaphus species inhabit forest floor decomposition zones including leaf litter, soil, and deadwood debris, indicating participation in soil detritivore communities.

• Other Euaesthetinae generaEdaphus is distinguished from related euaesthetine genera by combinations of genitalic morphology, punctation patterns, and body proportions; precise differentiation requires reference to genus-level keys for the subfamily.
