From Latin convector, noun in apposition, masculine = the fellow traveller, passenger, referring to its broad adventitious distribution along with its hosts. Distribution. Australia (Northern Territory); adventive in Brunei, Cambodia, India (Odisha), Laos, Malaysia (Sabah), Singapore, Thailand and the United States of America (Florida). Host plants. Acacia auriculiformis A.Cunn. ex Benth. and A. mangium Willd. (Fabaceae, Caesalpinioideae, mimosoid clade). Acacia auriculiformis, northern black wattle or ear-pod wattle, occurs in Australia, Papua New Guinea and Indonesia. Its distribution in Australia comprises the north of the Northern Territory including several off-shore islands as well as the Cape York Peninsula and the Torres Strait Islands, Queensland (Boland et al. 1990). In Papua New Guinea it occurs in the Central and Western Provinces, and extends into Irian Jaya (Papua Barat) and the Kai Islands of Indonesia. Acacia auriculiformis is naturalised widely in Africa, the Americas, Asia and Oceania (Vélez-Gavilán 2016). Acacia mangium, brown salwood or black wattle, has a similar distribution. It originates from Australia (northeastern Queensland), the Western Province of Papua New Guinea, Irian Jaya and the eastern Maluku Islands (Francis 2003). It has been planted throughout the tropics and is naturalised in many areas (CABI 2021). Comments. Acizzia convector sp. nov. is well characterised by its fore wing pattern and structure of the male and female terminalia in the adults as well as the chaetotaxy in the immatures. It resembles Acizzia beieri Loginova and A. jucunda Tuthill in the male proctiger with a long apical portion and a spine-like process adjacent to the posterior lobe, as well as the paramere with an anterior tooth on the fore margin. It differs from the former in the presence of a dark fore wing pattern and from the latter in two metabasitarsal spurs and the female terminalia bearing hooked long setae posteriorly., Published as part of Taylor, Gary S., Halbert, Susan E., Tripathy, Ashirwad & Burckhardt, Daniel, 2023, A new Australian species of invasive psyllid, Acizzia convector Burckhardt & Taylor, sp. nov.
