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.

Lisne buhe (Hemiptera: Sternorrhyncha: Psylloidea) sitni su kukci koje je u prirodi teško otkriti, posebno kada se nalaze u populacijama niskog intenziteta. Procjenjuje se da je u svijetu do danas opisano oko 4000 vrsta klasificiranih u sedam porodica. Samo manji broj vrsta ubraja se u važne poljoprivredne štetnike, a u posljednje vrijeme dobivaju na značaju zahvaljujući spoznaji da prenose uzročnike biljnih bolesti. Faunističko istraživanje lisnih buha u Hrvatskoj započelo je 2015. godine. Cilj ovog istraživanja bio je sastaviti popis vrsta lisnih buha prisutnih u Hrvatskoj, uz pregled pripadajućih biljaka domaćina, kao i utvrditi potencijalno prisustvo nekih do danas u Hrvatskoj nepoznatih vrsta. Odrasli primjerci lisnih buha uzorkovani su entomološkim kečerom ili metodom otresanja biljaka na bijelu podlogu te su usnim aspiratorom prikupljani u Falcon epruvete i do laboratorijske analize pohranjeni u 70% etilni alkohol. Identifikacija vrsta provedena je klasičnom makroskopskom i mikroskopskom analizom na osnovi morfoloških karakteristika odraslih stadija i genitalija mužjaka, vrlo rijetko i ženki, uz korištenje dihotomnih ključeva dostupnih u literaturi. U periodu od 2015. do 2021. godine sljedeće vrste lisnih buha iz porodice Psyllidae zabilježene su po prvi puta u Hrvatskoj: Diaphorina chobauti Puton, 1898, Arytaina genistae (Latreille, 1805), Cacopsylla brunneipennis (Edwards, 1896), Cacopsylla myrthi (Puton, 1876), Cacopsylla saliceti (Foerster, 1848), Livilla variegata (Löw, 1881), Psylla foersteri Flor, 1861 i Psylla hartigii Flor, 1861., Psyllids or jumping plant-lice (Hemiptera: Sternorrhyncha: Psylloidea) are a relatively small group of insects. Some 4000 species have been described so far, classified in seven families. Due to their smally body size they often go unnoticed on their host plants. Not many psyllid species are known as plant pests, but they have recently gained attention as vectors of some very harmful plant pathogens. Field survey of psyllid fauna in Croatia started in 2015, with an aim to compile a check-list of psyllid species, with an emphasis on detecting new, previously unrecorded species, together with their host plants. Adult psyllids were collected with entomological fine mesh sweeping net or by beating of branches on a white tray. Entomofauna was subsequently collected with a mouth aspirator and deposited into 70% ethanol until laboratory identification. Species were identified following classical identification methods based on morphological characteristics of adults and male, rarely female, genitalia, using identification keys available from the literature. During the period 2015-2021 following species from the family Psyllidae were recorded for the first time in Croatia: Diaphorina chobauti Puton, 1898, Arytaina genistae (Latreille, 1805), Cacopsylla brunneipennis (Edwards, 1896), Cacopsylla myrthi (Puton, 1876), Cacopsylla saliceti (Foerster, 1848), Livilla variegata (Löw, 1881), Psylla foersteri Flor, 1861 and Psylla hartigii Flor, 1861.

The colour preference of the plum psyllid,Cacopsylla pruni(Hemiptera, Psyllidae), is yet poorly studied. This species is the only known vector of the ‘CandidatusPhytoplasma prunorum’, the agent of European stone fruit yellows (ESFY), a devastating disease of several cultivatedPrunusspecies in Europe. As ESFY is still uncurable, vector control, thus vector monitoring, is pivotal to protect these trees.Cacopsylla pruniis a univoltine, host-shelter-alternating species; overwintered adults migrate from conifer to wild or cultivatedPrunusspecies (family Rosaceae) in late winter-early spring. To select the most effective colour indicating the arrivals of the immigrants, yellow, fluorescent yellow, white, red and transparent sticky traps were deployed in an apricot orchard in Hungary. The two most abundant species in sticky traps wereC. pruniandC. melanoneura. Catches of white traps were significantly biased towardsC. prunias compared toC. melanoneuraspecimens. Moreover, white sticky traps were better at catching plum psyllids than the other colours. Attraction to white was strongest when immigrants from shelter plants kept arriving in the orchard, coinciding with the blooming principal phenophase of apricot trees. When the host flowering growth stage was over, catches ofC. pruniin white traps declined sharply to the level of yellow traps that was highest during this post-blooming period. We recommended white sticky traps for promptly monitoringC. pruniin apricot orchards because it is more potent and more selective than yellow ones during the critically important early flowering interval.

Paratypes of Psylla initialis: Armenia: 13 ♂, 16 ♀, Meghri, along the Megriget bank, 07.vi.1955 (Loginova), (ZIN, dry and slide mounted). Other material examined. South Korea: 4 ♂, GB, Bonghwa-gun, Chunyang-myeon, Uguchi-ri, San 49, Uguchi Valley, 37°03'27.23"N 128°49'02.96"E, 750 m, 01.vii.2017, on Salix sp. (G. Cho), (NIBR, SNU, slide mounted and in 95% ethanol). Distribution in Korea. GB (NIBR, SNU). Host plant. Salix L. (Salicaceae). Comments. New record for Korea. Only male specimens are available from South Korea. In the Korean material, the apex of the paramere is slightly narrower than in Russian specimens. Based on the Russian material (ZIN) and the original description (Loginova 1966), Psylla initialis Loginova, 1966 belongs to Cacopsylla Ossiannilsson, 1970 and we transfer the species here as Cacopsylla initialis (Loginova, 1966), comb. nov.

Psylla (Hepatopsylla) silvestris Kwon, 1983 is a junior primary homonym of Psylla silvestris Bajeva, 1969 (ICZN 1999/2012: Art. 57.4) and, hence, Psylla (Hepatopsylla) silvestris Kwon, 1983, the junior homonym, is permanently invalid (ICZN 1999/2012: Art. 57.2). Here we propose Cacopsylla kwonorum Cho & Burckhardt, nom. nov. as a replacement name for Psylla (Hepatopsylla) silvestris Kwon, 1983. The new name is dedicated to Yong Jung and Jin Hyung Kwon in recognition of their fundamental work on the Korean Psylloidea. Based on the study of type material (ZIN) and the description by Bajeva (1969), Psylla silvestris Bajeva, 1969 belongs to Cacopsylla Ossiannilsson, 1970 and, therefore, we propose the following new combination: Cacopsylla silvestris (Bajeva, 1969), comb. nov., Published as part of Cho, Geonho, Burckhardt, Daniel & Lee, Seunghwan, 2022, Check list of jumping plant-lice (Hemiptera: Psylloidea) of the Korean Peninsula, pp. 1-91 in Zootaxa 5177 (1) on page 49, DOI: 10.11646/zootaxa.5177.1.1, http://zenodo.org/record/7021934, {"references":["Kwon, Y.

Psyllinae Latreille, 1807 Comments. Kwon & Kwon (2020) referred Anomoneura Schwarz to the subfamily Anomoneurinae. Immatures of Anomoneura resemble morphologically those of Psylla and Spanioneura (Ossiannilsson 1992; Liao & Yang 2018) suggesting a close phylogenetic relationship of the three genera. We, therefore, follow Burckhardt et al. (2021) and treat Anomoneura as a member of the Psyllinae. Kwon & Kwon (2020) subdivided the genus Psylla Geoffroy, 1762 into the subgenera Koreopsylla Kwon & Kwon, 2020 and Psylla s. str. as well as the genus Cacopsylla Ossiannilsson, 1970 into the subgenera Cacopsylla s. str., Edentatipsylla Li, 2005 (misspelt as Edentipsylla), Hepatopsylla Ossiannilsson, 1970, Megapteripsylla Kwon & Kwon, 2020 and Thamnopsylla Loginova, 1978. Cacopsylla visci (Curtis, 1835), the type species of the monotypic subgenus Koreopsylla, does not match the diagnosis and circumscription of Psylla provided by Cho et al. (2019b) and Burckhardt et al. (2021), respectively. Rather,the species agrees with the concept of Cacopsylla by Burckhardt et al.(2021).For this reason, Koreopsylla, syn. nov., is synonymised with Cacopsylla and C. visci is referred to Cacopsylla rather than to Psylla (Koreopsylla). The splitting of Cacopsylla into subgenera by Kwon & Kwon (2020) is problematic as these subdivisions are, at least in part, artificial. In the «best ML tree» of Percy et al. (2018: Figure S1) species previously referred to the subgenera Cacopsylla s. str. (represented by 2 species) and Thamnopsylla (2 spp.) constitute each a monophyletic clade but not those to Hepatopsylla (15 spp.). Kwon & Kwon (2020) treated Cacopsylla tobirae (Miyatake, 1964) in the subgenus Edentatipsylla (misspelt as Edentipsylla) and Cacopsylla bibari (Kwon, 1983) in the subgenus Hepatopsylla. Both species are associated with Pittosporum tobira (Pittosporaceae) and are probably closely related, i.e. congeneric, though differing in the absence/presence of a genual spine. Similarly, Cacopsylla japonica (Kuwayama, 1955) is closely related to C. albopontis (Kuwayama, 1908), C. lineaticeps (Kwon, 1983) and C. pseudosieboldiani (Konovalova & Loginova, 1985) and shares the host association with Acer (Sapindaceae). Kwon & Kwon (2020) refer C. japonica to the monotypic subgenus Megapteripsylla, based on the broad forewing, but treat the other three species in the subgenus Hepatopsylla. For this reason we follow Burckhardt et al. (2021) in not recognising subgenera within Cacopsylla, and synonymise Megapteripsylla, syn. nov. with Cacopsylla., Published as part of Cho, Geonho, Burckhardt, Daniel & Lee, Seunghwan, 2022, Check list of jumping plant-lice (Hemiptera: Psylloidea) of the Korean Peninsula, pp. 1-91 in Zootaxa 5177 (1) on page 35, DOI: 10.11646/zootaxa.5177.1.1, http://zenodo.org/record/7021934, {"references":["Latreille, P.

Unknown. Comments. Cacopsylla hanlabori was described by Kwon (1983) from a single female from Korea and is, according to Kwon & Kwon’s (2020) key, similar to C. elaeagni and C. elaeagnicola. It is said to differ from related species in the body colour and head structure. Material recently collected in Japan differs from C. elaeagni in the more slender genal processes and forewings (H. Inoue, pers. comm.). Whether this Japanese material belongs to C. hanlabori cannot be judged at present. More material, including males and immatures, as well as information on the host are necessary to evaluate the identity of C. hanlabori., Published as part of Cho, Geonho, Burckhardt, Daniel & Lee, Seunghwan, 2022, Check list of jumping plant-lice (Hemiptera: Psylloidea) of the Korean Peninsula, pp. 1-91 in Zootaxa 5177 (1) on page 45, DOI: 10.11646/zootaxa.5177.1.1, http://zenodo.org/record/7021934, {"references":["Kwon, Y.
