Description

Macrotrachelia nigronitens (Stål, 1860) (Heteroptera: Anthocoridae) is permanently present in the wild in Auckland (AK), New Zealand. It should therefore be added to the New Zealand Organisms Register (NZOR). It is a specialised predator of thrips inside leaf-roll galls. It has been present in New Zealand since at least the 1980s. Aspects of its biology, distribution, biosecurity status and history in New Zealand are discussed. The first detailed specimen records from New Zealand are provided, and a biological association is noted for the first time with Teuchothrips disjunctus on Callistemon, probably its main association in New Zealand, where only two species of thrips cause leaf-roll galls. It has not been found associated with other thrips in New Zealand. M. nigronitens is not known to be present in Australia, but the poorly known Anthocoris austropiceus Gross, 1954 has been reported, in an easily overlooked publication, to be associated with Teuchothrips disjunctus on Callistemon in Canberra. This led to an early tentative identification, by the author, of New Zealand material of M. nigronitens as A. austropiceus, in collections. This likely misidentification can now be discounted, but further research in Australia is required to determine the true identity of both A. austropiceus, and whatever species of anthocorid was found in Canberra.
