Native to North America, Corythucha arcuata (Say, 1832) (Hemiptera, Tingidae) is an invasive species
of lace bug in Europe (CSÓKA et al., 2020). It is mainly a pest of oak trees (Quercus spp.), but other
plant species have been recorded as hosts, namely trees such as Castanea dentata (Marsh.) Borkh.,
Castanea sativa Mill., Malus sylvestris (L.) Mill., Ulmus minor Mill., and Acer spp. and shrubs like Rosa
canina L., Rubus idaeus L., and Rubus ulmifolius Schott (ZÚBRIK et al., 2018; GOLUB & SOBOLEVA,
2018; CSÓKA et al., 2020).
Corythucha arcuata was first recorded in Europe from Italy by BERNARDINELLI &
ZANDIGIACOMO (2000), who suggested that the species had been introduced a few years earlier due
to its wide distribution in the Italian peninsula. In the following two decades, it has swiftly spread and
has already been found in 18 countries, the closest to Portugal being France, where it was detected in
2017 (CSÓKA et al., 2020; MERTELÍK & LIŠKA, 2020). To our knowledge, no Spanish records of C.
arcuata have been published yet.
In this paper, we present the first records of C. arcuata from the Iberian Peninsula, more
specifically in the district of Porto (Portugal).

The North American oak lace bug feeds on leaves of ‘white oaks” in its native range. In Europe, it was first discovered in northern Italy in 2000. In recent years, it has subsequently spread rapidly and population outbreaks have been observed in several European countries. In the present study, we summarize the steps of its expansion. To predict its potential host range, we checked 48 oak species in 20 sentinel gardens in seven countries between 2013 and 2018. In total, 27 oak species were recorded as suitable hosts; 13 of them are globally new ones, 23 out of the 29 in section Quercus (∼ white oaks, an intrageneric taxonomic unit within genus Quercus), including Asian oaks, native to Japan, Korea and China, and four out of five in section Cerris (another intrageneric unit of the same genus), were accepted as hosts. None of the species in section Lobatae (red oaks) or in the Ilex group was accepted. Host records were also collected in forest stands of 10 countries. We found 11 oak species that were infested. Outbreak populations were most commonly found on Quercus robur, Quercus frainetto, Quercus petraea and Quercus cerris, comprising widespread and outstandingly important oaks species in Europe. Based on our findings, we conclude that suitable hosts for oak lace bug are present in most of Europe and Asia. This means that a lack of hosts will likely not restrict further range expansion.

The oak lace bug Corythucha arcuata (Say) (Heteroptera, Tingidae) has been observed in northern Iyaly (Lombary and Piedmont regions) since May 2000. The host plants found up to now in Italy are Quercus robur, Q. pubescens and presumed hybrids of Q. robur and Q. petrea. This is the first record of occurrence of this nearctic species in Europe. The pest is spread over a wide area, suggesting that it was introduced some years ago. Brief notes are given on the morphology, geographical distribution, host plants, biological cycle, injury and control of this pest.

The paper presents an original key for the identification of three harmful species of the lace bugs (Heteroptera: Tingidae) distributed in the south of the European part of Russia: the Palaearctic Stephanitis pyri (Fabricius, 1775) and the Nearctic Corythucha arcuata (Say, 1832) and C. ciliata (Say, 1832); the last two species are invasive in Europe.
