Australian Heloridaw, including Monomachidae (Hymenoptera)

Abstract

The genera Helorus, Monomachus, Ropronia, Vanhornia, and Tetraconus are considered to belong in one family, the Heloridae, rather closely allied to the genus Austroserphus of the family Proctotrupidae. A new genus (with three new species) combining many of the characters of the above genera is described as well as a new species and a new subspecies of Monomachus.
