Hi! According to Aphid Species File (http://aphid.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=1166527 ) it has been described as Syphocoryne artemisiae. The journal Redia is accessible at BHL. So, this should be the original description: http://biodiversitylibrary.org/page/15499193 (start of paper), http://biodiversitylibrary.org/page/15499196 (name), http://biodiversitylibrary.org/page/15499405 (Tab. X). The text is in Italian, I hope it is helpful to you. Regards
