Lycorma delicatula (Hemiptera: Auchenorrhyncha: Fulgoridae: Aphaeninae) finally, but suddenly arrived in Korea

A history of name changes in two fulgorid species – Lycorma delicatula and Limois emelianovi – is reviewed. Lycorma delicatula was once mistakenly reported to occur in Korea. Now, it has suddenly become common in western Korea, creating the suspicion that it has recently arrived from China and settled in Korea. A brief morphological and biological description of L. delicatula is provided, and its original Korean name, “ggot‐mae‐mi”, is revalidated. Limois emelianovi , sometimes considered a synonym of emeljanovi , is the correct name for this species, as emeljanovi is simply another transliteration of the personal name Emelianov, Emeljanov or Emel’yanov. The name emelianovi stands correct based on the International Code of Zoological Nomenclature code 32.5.1, because there is no internal evidence of an inadvertent error, and an incorrect transliteration is not considered an inadvertent error. The cytochrome oxidase I (COI) barcoding regions of both species were sequenced and compared for future reference.
