NOTE: As of 2014, the California Beetle Project page is no longer updated. The original database and list of California beetles in the menu on the left will remain for the time being, but the information contained within is not necessarily current. SBMNH Entomology Curator Matthew L. Gimmel has divided up the function of the original database into two conceptual halves:

  1. The SBMNH Entomology specimen-level database, including all SBMNH beetle specimens included in the CBP database, which is now available (and ever-growing) through the ecdysis portal at https://serv.biokic.asu.edu/ecdysis/

  2. A literature- (and available specimen-)based checklist.
    3. of the Coleoptera of California, which is being revised and re-compiled by Dr. Gimmel, and, as of January 2017, is about 85% complete.

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.
