Dasycerinae is a subfamily of rove beetles.[1] Dasycerinae currently only contains 1 extant genus and 3 extinct genera.[2]

Genera

There are currently 4 described genera in Dasycerinae:[2]

†Cedasyrus Yin & Cai, 2020
Dasycerus Brongniart, 1800
†Protodasycerus Yamamoto, 2016
†Vetudasycerus Cai, Thayer, Newton, Yin & Huang, 2018

(† = extinct)
Anatomy

They have antennae with 11 segments and trisegmented antennal clubs. The tarsi have three segments, and the elytra cover or nearly cover the entire abdomen.
Ecology

These beetles inhabit moist broadleaf forest litter.[3] Eastern species are wingless with small eyes; dissected females have only been found with a single egg. They are known to occur on fruiting fungi, but may not specifically feed on them.
