Also found in: Wikipedia.
a family of polyphagous beetles. The body, which is 3–5 mm long, ranges in color from yellow to brown. The antennae are long and clavate, and the elytra are shortened. The legs are three-jointed and have a single claw. There are two subfamilies, embracing approximately 4,000 species. Ninety species are found in the USSR. Beetles of the subfamily Pselaphinae have eyes and highly developed palpi on the lower jaws; they feed on decomposing matter. Beetles of the subfamily Clavigerinae have no eyes, and their palpi are incompletely developed. They live in anthills, where the ants feed them and then collect secretions from the abdominal glands of the beetles.
