What it looks like: 4-5mm in length. Its body is light to dark reddish brown, flattened, and with rounded elytra. The pronotum is smooth, while the elytra have distinct rows of punctured striae. Its antennae are elongate, and gradually widened toward the tips.

Where you'll find it: From higher elevations of southern California (including the San Jacinto and San Bernardino ranges) north through the Sierra Nevada into Oregon.

Natural History: This species is probably a general scavenger on decaying organic material. It is most often found under and among debris in moist places, especially along montane streams. They are primarily active at night, and may then be found out running around stream edges.
