}}Japananus hyalinus, the Japanese Maple Leafhopper, is a species of leafhoppers of the subfamily Deltocephalinae, tribus Opsiini[2] (formerly placed in tribus Scaphytopiini). Believed to be native to eastern Asia, it has been carried with the trade in cultivated maples and is now widely found in Europe, North America and Australia.[3][4] DescriptionFemale 5.5mm long (even 6.5mm[5]), male 4.25mm. Head comes to an acute point, head and prothorax greenish yellow. Forewings translucent with reddish veins (paler in male). In the resting position three narrow beaded bands of purplish-brown colour run more or less straight across the wings, incorporating some portions of the veins.[1] Scutellum yellow with dark markings resembling the "frowny" emoticon ☹. The eggs are inserted into the nodes of young branches, making them very difficult to detect in dormant planting stock. There is normally one generation per year (two in Italy), with the eggs over-wintering.[4] The nymphs are sharply pointed at both head and tail and are frequently yellowish. Origin and spreadThe species was first described (as Platymetopius hyalinus) by Herbert Osborn in 1900, from specimens taken in Washington, D.C. Since it was unlikely that a native species would have remained undetected so long, he suggested it was an introduced species brought in with exotic plants.[1] This was confirmed in 1931 when P. W. Oman identified Platymetopius hyalinus with P. cinctus, described by Matsumura in 1914 and found in Hokkaido, Honshu and Kyushu.[5][10] In 1931 Elmer Darwin Ball designated P. hyalinus as the type (and, at the time, only) species of a newly differentiated genus Japananus. Since then a further five species have been placed in this genus. Apart from hyalinus they are all native to mainland Asia and show no tendency to major range expansions.[11][12] In North America J. hyalinus has been recorded from North Carolina in the south to Ontario in the north.[4] The first European records, from Austria and Romania, were published in 1961, followed by reports from Germany, the former Czechoslovakia and Yugoslavia (1987), Bulgaria and Hungary (1989), France, Spain and Northern Italy (1994), Slovenia (2002), Serbia and Southern Russia (2003), Luxembourg (2010) and Poland (2012).[3] It was discovered in Australia in 1997.[15] The status of J. hyalinus in the United Kingdom is currently uncertain. In 1999 two insects were found during inspections of imported Acer palmatum stock that originated from South Korea. In August 2014 the insect seen in the Taxobox was photographed in Cambridge, where the complete breeding cycle has been observed.[4] Host plantsIn its Asian home range the host plants are Acer japonicum and A. palmatum. In other places it readily adapts to other Maple species, which no doubt assists its spread. In Europe the main food plant is field maple (Acer campestre),[3] and it has been recorded from box elder, Norway maple, sycamore, silver maple, Montpellier maple, Acer buergerianum, A. truncatum and red maple.[4] Economic impactLeafhoppers are regarded with some suspicion by plant-growers, both because of the additional load they place on plant metabolism and their ability to act as vectors for virus diseases and phytoplasma diseases such as flavescence dorée (FD).[20] As of 2014 J. hyalinus is not known to be a disease vector and its potential to cause significant damage is assessed as very small.[4] References1. ^1 {{cite web|title=Japananus hyalinus (Osborn)|website=Key to the leafhoppers and treehoppers of Australia and neighbouring areas (Hemiptera: Auchenorrhyncha)|author=Fletcher, M.J.|date=2009|url=http://www1.dpi.nsw.gov.au/keys/leafhop/species/japanan.htm|accessdate=21 December 2014|publisher= Agricultural Scientific Collections Unit, NSW Govt.}} [1][2][3][4][5][6][7][8][9][10]2. ^1 {{cite journal|author1=Gaffuri, F. |author2=Sacchi, S. |author3=Cavagna, B. |title=First detection of the mosaic leafhopper, Orientus ishidae, in northern Italian vineyards infected by the flavescence dorée phytoplasma|doi=10.5197/j.2044-0588.2011.024.022|journal=New Disease Reports|year=2011|volume=24|page=22}} 3. ^1 2 {{cite journal|author=Matsumura, S.|year=1914|title=Die Jassinen und einige neue Acocephalinen Japans|trans-title=The Jassinae and some new Acocephalinae from Japan|journal=Journal of the College of Agriculture, Tohoku Imperial University, Sapporo|volume=5|issue=7|at=pp. 165-240 (at p. 215)|url=http://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/12517/1/5%287%29_p165-240.pdf|language=German}} 4. ^1 {{cite journal|author=Oman, P.W.|year=1931|title=New Jassinae, with notes on other species|journal=Journal of the Washington Academy of Sciences|volume=21|issue=17|pages=430–436|url=http://biostor.org/reference/105922.text}} 5. ^1 2 3 {{cite journal|author=Osborn, H.|year=1900|title=A neglected Platymetopius|journal=Entomological News|volume=11|pages=501–502|url=https://www.biodiversitylibrary.org/page/2588684#page/235/mode/1up}} 6. ^1 2 3 4 5 6 {{cite web |title=Rapid Pest Risk Analysis (PRA) for Japananus hyalinus |archiveurl=https://www.webcitation.org/6UyI1RJhC?url=https://secure.fera.defra.gov.uk/phiw/riskRegister/plant-health/documents/japanusHyalinus.pdf |url=https://secure.fera.defra.gov.uk/phiw/riskRegister/plant-health/documents/japanusHyalinus.pdf |publisher=Food & Environment Research Agency |author=Tuffen, M. |date=17 September 2014 |accessdate=20 December 2014 |archivedate=20 December 2014 |display-authors=etal |deadurl=yes |df= }} 7. ^1 2 3 {{cite journal|author1=Walczak, M. |author2=Musik, K. |author3=Mokrzycka, A. |year=2012|title=Japananus hyalinus (Osborn, 1900) - a new leafhopper for Polish fauna (Hemiptera: Cicadomorpha)|journal=Wiadomosci Entomologiczne|volume=31|issue=4|pages=242–250|url=http://pte.au.poznan.pl/we/2012/WE31-4_06_walczak_i_in.pdf}} 8. ^1 {{cite journal|title=A taxonomic study on the genus Japananus Ball (Hemiptera, Cicadellidae, Deltocephalinae), with description of one new species from China|year=2008|author1=Xing, J. |author2=Dai, R. |author3=Li, Z. |journal=ZooKeys|volume=3|pages=23–28|doi=10.3897/zookeys.3.24}} 9. ^1 {{cite journal|title=Two new species of the genus Japananus Ball, 1931 (Hemiptera: Cicadellidae: Deltocephalinae)|year=2010|author1=Xing, J. |author2=Dai, R. |author3=Li, Z. |journal=Zootaxa|volume=2415|pages=63–68|url=http://www.mapress.com/zootaxa/2010/f/z02415p068f.pdf}} 10. ^1 {{cite journal|title=A review of the tribes of Deltocephalinae (Hemiptera: Auchenorrhyncha: Cicadellidae)|author1=Zahniser, J.N. |author2=Dietrich, C. |year=2013|journal=European journal of taxonomy|volume=45|doi=10.5852/ejt.2013.45}} }} External links
