The leafhopper family Cicadellidae (Hemiptera: Auchenorrhyncha) is plant feeders, with mouthparts adapted for sucking. Almost of the them cause injuries of destruction to plants, including fruit trees and grain crops, and can be vectors of plant diseases. Therefor, Cicadellidae is one of the most important pests in the world. However, their identifications are very difficult because of small size and morphological similarities, and their exact biological information such as host plants, life cycle and distribution are not clear for most species. So, we provide and integrated biological database that present accurate diagnostic methods and ecological infromation.

The leafhopper subfamily, Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae), caused direct damage by sap-sucking or indirect damage by transmission of viruses or diseases to the host plants, so Typhlocybinae is one of the most important insect pests in agriculture, urban ecology, forest, etc. in the world. However, their identifications are very difficult due to small size and morphological similarities, and their exact biological information such as host plants and life cycle are not reported yet for most species. So, we construct an integrated biological database that presents accurate diagnostic methods (illustrated key characters, DNA barcoding data), patterns and seasons of occurrences, and some ecological photographs such as dorsal habitus of specimens and plant damages

The subfamily Iassinae Walker belongs to the family Cicadellidae (Hemiptera: Auchenorrhyncha). A total of 124 genera with 1,999 species have been described in the world. To date, two genera, Batracomorphus Lewis and Iassus Fabricius, and 5 species of the subfamily have been recorded in Korea. In this talk, one new species and one new record of the genus Batracomorphus and one new species and two new records of the genus Iassus from Korea are presented. And we also provide biological information such as host plants and distributional records of the Korean Iassine species.

Leafhopper subfamily, Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae), caused direct damage by sap-sucking or indirect damage by transmission of viruses or diseases on the host plants, so typhlocybinae is one of the important pest groups in the world. Typhlocybinae distribute worldwide and a total of 471 genera and more than 4,300 species have been described. so far, 38 genera and 102 species were recorded in the Korean Peninsula. In this talk, we provide several taxonomic studies for the Korean typhlocybene fauna based on the genus-level reviews of the subfamily from the Korean Peninsula.

Genus Tautoneura Anufriev, 1969 (Hemiptera: Auchenorrhyncha: Cicadellidae: Typlocybinae) were recorded 59 species in the world. Among them, only 1 species: Tautoneura mori has been recorded so far in the Korean Peninsula. Tautoneura mori is known as a major pest of Mulberry in China and Japan, and we also confirmed that it appears on Mulberry in Korea. In this talk, we confirmed two new records: Tautoneura japonica, Tautoneura tricolor to the Korean typhlocybinae fauna, and we also discovered one new species to science. Additionally, we provide biological information such as host plants and distributional records, with a key to the Korean Tautoneura species. We also discuss potential status of each species as an agricultural pest concerning its biological traits.

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 Arboridia Zachvatkin belongs to the tribe Erythroneurini of the subfamily Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae). A total of 69 valid species have been described in the Palaearctic and Oriental region. So far, seven species of this genus have been recorded in the Korean Peninsula. In this study, we present two new species, Arboridia sp. nov. 1, Arboridia sp. nov. 2, and provide a key to the Arboridia species in the Korean Peninsula with biological information such as host plants and distributions.
