== Description == Members of ''Cyrtomon'' are mid-sized (12–24&nbsp;mm) and can be recognized by their dense and uniform scale coverage, which is grey to green or brown in coloration. Their elytral shoulders are well developed.

Lanteri provides the following diagnosis for ''Cyrtomon'':<ref name=":3"/>
