What it looks like: 2-3 mm in length. Its body is shiny, reddish-brown, oval-shaped, and more elongated than the other species in its genus. It has distinctly clubbed antennae and hairs cover its entire surface. The male hind femur has a large, sharp tooth.

Where you'll find it: This species is found in coastal California and Oregon.

Natural History: These beetles are rarely collected and very little is known about their habits and habitat. Like most leiodids, they are probably subterranean fungus feeders. They have been collected in leaf litter and flight traps between the months of March and May.
