현재까지 전세계적으로 Periphyllus allogenes (개성진사진딧물)은 무시성충세대에 대한 형태학적 정보만이 보고되었다. 본 연구에서는 2021 년부터 2022년까지 한국 가평군, 홍천군에서 그동안 P. allogenes의 알려지지 않았던 간모, 유시성충 세대를 채집하여, 이들에 대하여 형태학적 정 보, 분포지역, 기주식물, 생태 사진을 처음으로 보고한다.
The genus Periphyllus has been revised as seven species in the Korean Peninsula. Recently, Periphyllus hokkaidensis Sorin 1990 is newly discovered on the young shoot of Acer mono subsp. okamotoanum in Ulleung Island. This is the first record found P. hokkaidensis in other areas except Hokkaido, its origin region. As the result of this study, we announce totally eight species in this genus and present description and illustration of P. hokkaidensis with apterous viviparous females.
The genus Periphyllus is tree-dwelling group, mostly on maple tree (Acer spp.). In this study, we discovered one species new to Korea, P. loricatus (Pashtchenko 1987) on A. ginalla. In prior to Pashtchenko(1987), Periphyllus ginallae Paik in Szelegiewicz (1974) seems the same species, nevertheless, treated as 'nomen nudum' without any description. As a result of our revision, totally seven species belong to this genus in the Korean peninsula.
