Dasycerinae


The Dasycerinae are a subfamily of the Staphylinidae rove beetles.

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.
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.

Systematics

The lone genus, Dasycerus Brongniart 1800, has four species in North America, and they are also found in the Palearctic and Oriental regions.
