What it looks like: 1.9-2.0 mm in length. It's body is elongated, yellowish-brown, and covered in rows of small hairs. Dirt particles stick to these hairs, masking the beetle's true color and providing camouflage as it moves across the ground.

Where you'll find it: This rare beetle is known from California's coast ranges and central Sierra Nevada. It is the only species in its genus found west of the Rockies. In the coast ranges it had previously been known only as far south as Paso Robles. However, we have recently discovered it along the crest of the Santa Ynez range above Santa Barbara.

Natural History: They live and feed on fruiting bodies of fungi and in forest litter.
