Amphichroum maculatum
Amphichroum maculatum is a species of rove beetle in the family Staphylinidae, subfamily Omaliinae. It is a small beetle found in western North America, with records from British Columbia south through Washington, Oregon, and California, and east to Nevada. The specific epithet "maculatum" (spotted) suggests a patterned appearance, though detailed morphological descriptions are limited in available sources. As a member of the Omaliinae, it likely inhabits moist terrestrial environments where these beetles are commonly encountered.
