40FB2815B957569AB37D133C264A8180.taxon	diagnosis	Diagnosis. Although a number of undescribed species of Acizzia associated with Dodonaea have been reported recently, and are in the process of being described (McClelland et al. 2025), the only currently described species of Acizzia associated with Dodonaea is Acizzia dodonaeae (Tuthill, 1952). Geographically, distributions of A. aliceae and A. dodonaeae do not overlap, and the two species are easily distinguished morphologically due to the absence of any wing pattern in A. aliceae. Furthermore, the male parameres of A. aliceae are broader and less sinuous than those of A. dodonaeae, while the female proctiger is less arched posteriorly (Tuthill 1952).	en	Martoni, Francesco, Tweed, James M.

40FB2815B957569AB37D133C264A8180.taxon	etymology	Etymology. The species epithet was chosen to honour the Australian entomologist, Dr Alice Wells, for her fundamental contribution to entomology in the Austro-Pacific. Dr Wells was likely the first person to collect this species during the 2012 – 2014 survey (Maynard et al. 2018).	en	Martoni, Francesco, Tweed, James M. H., Blacket, Mark J., Percy, Diana M.

5A9053FF33745E9FA9E321861972300C.taxon	diagnosis	Diagnosis. The shape of the fore wing of P. aewagriini, which is elongate and narrow (> 2.6 × longer than wide), as well as the pigmentation pattern, clearly aligns this taxon with other Pseudophacopteron in the Austro-Pacific region (Malenovský 2008); the type species, P. tuberculatum Crawford, as well as most other taxa also found on Apocynaceae host plants, have a fore wing that is pyriform and broad (length <2.6 × width) (Malenovský 2008; Malenovský and Burckhardt 2009; Malenovský et al. 2015). A similar narrow wing morphology to that of P. aewagriini can be observed in some of the African Pseudophacopteron species such as P. nigritulum Malenovský and Burckhardt and P. wagneri Malenovský and Burckhardt (Malenovský and Burckhardt 2009), but in these cases the vertex lacks a distinct median ridge, and only P. wagneri is possibly associated with Apocynaceae.

5A9053FF33745E9FA9E321861972300C.taxon	etymology	Etymology. The name epithet uses the Norf’k (local resident language spoken on Norfolk Island) word “ aewagriin ” that refers to the host plant, Alyxia gynopogon, known on Norfolk Island as the Evergreen. The name is treated as a Latinised noun, gender masculine, in genitive case. This name was chosen by receiving multiple nominations during the Norfolk Island Flora and Fauna Society meeting, held on Norfolk Island on the 10 June 2023. Members of the society remarked on the importance of such a species that has managed to “ hairng orn ” (hold its place) on Norfolk Island.	en	Martoni, Francesco, Tweed, James M.

5A9053FF33745E9FA9E321861972300C.taxon	distribution	Distribution. This species is the only Pseudophacopteron present on Norfolk Island, and has been recorded from locations throughout Norfolk Island National Park (Fig. 15). The species has also been recorded within Selwyn Reserve, a Norfolk Island Regional Council reserve which adjoins the western border of the National Park (G. Maynard, pers. comm. 2024; Fig. 15). The distribution of this species is limited by the distribution of the host plant, which although common within the National Park, is scarce across the rest of the island group. No specimens have been found on the few plants that have been located and inspected outside of the National Park and Selwyn Reserve and it is likely P. aewagriini is confined to the National Park and its immediate surrounds.	en	Martoni, Francesco, Tweed, James M.
