<paragraphid="2B797E9875E41BC7CDD1923E1FD90411">This species was named in honour of the collection locality and Ceduna Area School students who collected the specimen. This species is colloquially known by the students as the ‘ golden-bum wasp’, however a collaborative decision was made to have the formal scientific name be more broadly relevant to the local community. The epithet ‘ ceduna’ is a noun in apposition.</paragraph>
