Quick identification Discolomatidae are oval to almost circular, strongly flattened, with 9- or 10-segmented antennae and a 1-segmented club. They can always be distinguished by the structure of the coxae (second figure) all three pairs of which are transverse but partly enclosed so that they appear to be globular and widely separated.
