Galerita is a of ground beetles in the Carabidae, containing over 90 described . Members are commonly known as False Bombardier Beetles due to their resemblance to bombardier beetles (Brachinus), though they lack the explosive chemical defense mechanism. The genus was established by Fabricius in 1801 and belongs to the tribe Galeritini within the Dryptinae. These beetles are primarily distributed across the Americas, with species found in North, Central, and South America.
