03A736490C333A0EFF34FC52FC6AD890.taxon	description	Acanalonia bivittata is the second species of the family introduced in Europe. It is reported from Canada (Ontario), eastern and south USA (where it ranges from Maine to Florida, and west to Minnesota, Kansas, Texas, and Arizona) and Mexico (Bartlett et al., 2014). The species was collected by the first author in northern Italy (Veneto region) in the summer of 2021 and 2022.	en	Sanna, Francesco, Poggi, Francesco (2022): First record of three alien Auchenorrhyncha species from Europe: Acanalonia bivittata (Say, 1825), Branchana xanthota Li, 2011, and Dryadomorpha pallida Kirkaldy 1906 (Hemiptera: Auchenorrhyncha: Acanaloniidae, Cicadellidae).

According to Wilson & McPherson (1981), who studied the life history of Acanalonia bivittata in southern Illinois, the species is univoltine and adults hatch from mid-July and can be found up to October. According to Wilson & McPherson (1980) and again based on observations made in Illinois, the species is highly polyphagous. In Italy, from observations made in 2022 adults were seen or captured on Erigeron canadensis L. (Asteraceae), Equisetum ramosissimum Desf. (Equisetaceae), Oxalis corniculata L. (Oxalidaceae), Populus alba L. (Salicaceae), Setaria pumila (Poir.) Roem. & Schult. (poaceae) and other plants, data which confirm the high polyphagy of the species.	en	Sanna, Francesco, Poggi, Francesco (2022): First record of three alien Auchenorrhyncha species from Europe: Acanalonia bivittata (Say, 1825), Branchana xanthota Li, 2011, and Dryadomorpha pallida Kirkaldy 1906 (Hemiptera: Auchenorrhyncha: Acanaloniidae, Cicadellidae).

03A736490C313A0FFF34FEEFFAB7DEF0.taxon	biology_ecology	Biology and host plants. B. xanthota is a bamboo-feeding leafhopper. In China it was reported from Qiongzhuea communis Hsueh & Hi and Phyllostachys edulis (Carrière) J. Houz. (Chen et al. 2012), while in Japan from Phyllostachys edulis, Phyllostachys reticulata (Rupr.), and Pleioblastus simonii (Carrière) (Kamitani, 2018). In northern Italy (Lombardia region) it was collected both by light trap and from Phyllostachys aurea Carrière (naturalized alien species), in woodland habitat in a hilly pre-alpine area; in both cases only adults were found. There are no published data on the life cycle of this species.	en	Sanna, Francesco, Poggi, Francesco (2022): First record of three alien Auchenorrhyncha species from Europe: Acanalonia bivittata (Say, 1825), Branchana xanthota Li, 2011, and Dryadomorpha pallida Kirkaldy 1906 (Hemiptera: Auchenorrhyncha: Acanaloniidae, Cicadellidae).

03A736490C313A0FFF34FEEFFAB7DEF0.taxon	discussion	Remarks. The male genital characters of the specimens collected in Italy match with those of the Chinese specimens, according to the description and drawings by Li et al. (2011) and Chen et al. (2012). This is not the case with the Japanese specimens which show some differences, according to the description and drawings by Kamitani (2018), reporting the four apical processes of the aedeagus clearly shorter and not sinuous (difference also noted by the Japanese author, only for the length of the upper pair) and the apexes of the anterior arms of connective convergent and contiguous apically (not convergent and not contiguous apically in Chinese and Italian specimens). For this reason, we cannot exclude the possibility that the Japanese specimens may belong to a different still undescribed Branchana species; further morphological and genetic studies would be advisable.	en	Sanna, Francesco, Poggi, Francesco (2022): First record of three alien Auchenorrhyncha species from Europe: Acanalonia bivittata (Say, 1825), Branchana xanthota Li, 2011, and Dryadomorpha pallida Kirkaldy 1906 (Hemiptera: Auchenorrhyncha: Acanaloniidae, Cicadellidae).

According to observations made by the first author in Bovolone (VR) up to August 2022, the species seems to be able to complete 2 – 3 successive generations per year, with adults mainly present from early July to late September / early October, and juvenile stages present in June and from late July to the end of September. No adults were observed before the end of June. Both young and adults mainly live on lower leaf surface, where they cause superficial browning due to their trophic activity. So far, in northern Italy, adults and nymphs (1 st to 5 th instar) have mostly been obtained from the ornamental tree Lagerstroemia indica L. (in Italy cultivated or casual alien species), as well as reported for adults in Korea (Kim & Jung, 2022). The specimens were found only on unpruned trees, while no specimens were found on ornamental trees periodically pruned by removing 1 – 2 years old branches during winter. The evidence suggests that the species probably overwinters as eggs that are laid under the bark of the young branches. D. pallida has been reported also from Ziziphus jujuba Mill. (Zhang & Webb, 1996), present in Italy both as cultivated and as naturalized alien species, and Lumnitzera racemosa Willd. (Evans, 1966), absent in Italy.	en	Sanna, Francesco, Poggi, Francesco (2022): First record of three alien Auchenorrhyncha species from Europe: Acanalonia bivittata (Say, 1825), Branchana xanthota Li, 2011, and Dryadomorpha pallida Kirkaldy 1906 (Hemiptera: Auchenorrhyncha: Acanaloniidae, Cicadellidae).

03A736490C373A0BFF34FD0FFA89DC14.taxon	discussion	Remarks. The general appearance of the 5 th instar nymph, matches the description provided by Dmitriev (2004) for the genus Dryadomorpha, based on Dryadomorpha metrosideri (Osborn, 1934) nymph. Differently from D. metrosideri, D. pallida presents an apical process on head and a longitudinal carina on face, characters that allows to clearly distinguish the two species. These morphological differences between the nymphs suggest that D. pallida and D. metrosideri are distinct taxa, unlike the possibility considered by Gnezdilov (2022) that they could be a single species. It is also noteworthy that the head of Dryadomorpha nymphs, according to the species, can have a longitudinal carina, as well as others Drabescini nymphs and differently from what Dmitriev (2004) reported.	en	Sanna, Francesco, Poggi, Francesco (2022): First record of three alien Auchenorrhyncha species from Europe: Acanalonia bivittata (Say, 1825), Branchana xanthota Li, 2011, and Dryadomorpha pallida Kirkaldy 1906 (Hemiptera: Auchenorrhyncha: Acanaloniidae, Cicadellidae).
