Abstract

Two newly recorded species of the genus Arboridia Zachvatkin (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae) from Korea are reported, which are Arboridia lunula Song & Li, 2013 and Arboridia agrillacea (Anufriev, 1969). Photographs of dorsal habitus, illustrations of male genitalia, abdomens and forewings and distributional records are provided. In addition, a key to the Korean Arboridia species is also given.

초록

Arboridia(두점박이애매미충) 속(노린재목: 매미아목: 매미충과: 매미충아과)의 국내 미기록 2종인 Arboridia lunula Song & Li, 2013 와 Arboridia agrillacea (Anufriev, 1969)을 기록한다. 성충의 사진과 함께 수컷의 생식기와 복부, 날개의 그림과 채집기록을 기재한다. 또한 국내 Arboridia 속의 검색표를 제공한다.


    The genus ArboridiaZachvatkin, 1946 belongs to the tribe Erythroneurini of subfamily Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae). Some members of the genus Arboridia are known as grape pests in the world as well as in Korea, and most of them have been also known as pests on cherry, hawthorn, pear, peach, apple, mulberry, maple, woodbine, dogwood, and several other plants (Song & Li, 2013). A total of 69 valid species have been described in the Palaearctic and Oriental regions (Song & Li, 2013). So far, eight species of this genus have been recorded in the Korean Peninsula (Kwon & Huh 2001).

    In this study, two new records of the genus from the Korean Peninsula are reported, and descriptions, genital illustrations and dorsal habitus of the species with a key to the Korean Arboridia species are presented. The specimens used for this study are stored at Laboratory of Systematic Entomology, Chungnam National University, Daejeon, Korea. The genital segments were detached from abdomen and macerated 10% KOH for about 60 min for dissection to examine male genitalia.

    Diagnoses

    The genus Arboridia can be identified by vertex with one or two pair of dark spots, and style apex with 3 points. Pronotum without conspicuous pits. Abdominal apodemes small and pygofer lobes without thick bristles. Subgenital plates have one group bristles at the middles of outer margin.
