Genus Greenidea Schouteden Remarks: An exclusion from the list is Greenidea (Trichosiphon) psidii van der Goot. There are a series of slides for this species (originally recorded as Greenidea formosana), from a single collection instance in Queensland, containing an alate ovipara, and an aptera with no host records. The aptera is unfortunately missing siphunculi, as they commonly detach when slide mounting this genus, and without which a definite identification is impossible. Halbert (2004) notes having a slide mounted specimen that is likely this species from Brisbane, but as yet it remains absent from Australian institutions. Further collecting and slide mounting is therefore needed to prove the species is present on the continent with any certainty., Published as part of Brumley, Cameron, 2020, A checklist and host catalogue of the aphids (Hemiptera: Aphididae) held in the Australian National Insect Collection, pp. 575-600 in Zootaxa 4728 (4) on page 594, DOI: 10.11646/zootaxa.4728.4.12, http://zenodo.org/record/3626584, {"references":["Halbert, S.

We report the discovery of the invasive aphid Aphis lugentis for the first time in Australia. This aphid specialises on Compositae, particularly on Senecio species. Aphids were tended by several ant species at a site on Kangaroo Island, South Australia, which is unlikely to be the location of the original introduction. We recommend the investigation of the distribution of A. lugentis in Australia and its impacts on plant hosts including threatened species and associated native ant and aphid community structures.
