Species in genus Megymenum have extended or greatly expanded pronotal margins (as in the type species M. dentatum) with a rounded scutellum: characteristic of the Dinidoridae. In most species the second valvifers are reduced, lightly sclerotised, and fused in the middle. Some species have reduced hemelytra and are flightless.^[3]
