Abstract
Megadrymus Gross is an endemic seed bug genus that occurs in subtropical and tropical wet and dry rainforest on the eastern and northern coasts of Australia. The genus is revised with the redescription of the type species M. terraereginae Gross, the transfer of Brentiscerus tenuicornis (Gross) to Megadrymus, and the description of five new species: M. aurorae, sp. nov., M. brunneus, sp. nov., M. capeyorkensis, sp. nov., M. kakadu, sp. nov. and M. refugiensis, sp. nov. A key to species is included. A phylogeny, and biological and distributional information, are presented and discussed.
Additional keywords: Australia, Heteroptera, new species, new combination, phylogeny, rainforest, Rhyparochromidae, taxonomy, vine scrub.
