Micropeplinae
Micropeplinae is a small subfamily of rove beetles (Staphylinidae) characterized by 9-segmented antennae with single-segmented clubs and a tarsal formula of 4-4-4 (appearing as 3-3-3). The group comprises approximately six extant genera worldwide, including Micropeplus, Kalissus, Cerapeplus, Peplomicrus, and Arrhenopeplus, plus the extinct †Protopeplus from Burmese amber. Species are primarily associated with moist microhabitats and feed on mold spores and fungal hyphae.
