Cryptotympana atrata belongs to the family Cicadidae, has long been recognized as a damaging plant-sucking pest, and is distributed in East Asian countries. In addition, their cries cause direct harm to us through noise pollution and also reported twig damage in the forest environments. In this study, we isolated strains of the entomopathogenic fungus Metarhizium that occurred from C. atrata collected this year. Here, we provide the morphological character and molecular phylogenetic relationship of this species. This is the first record of the entomopathogenic fungus Metarhizium viridulum isolated from C. atrata in Korea and provides a candidate strain with potential use for biological agents.

Chrysaster Kumata, 1961는 Gracillariidae (나비목: 가는나방상과)의 Lithocolletinae에 속해 있으며 우리나라에는 Chrysaster hagicola Kumata, 1961 한 종만이 알려져 있다. 본 연구에서는 동속의 국내 미기록종인 Chrtsaster ostensackenella (Fitch, 1859)를 처음으로 소개한다. 본 종의 유충과 성충은 Robinia pseudoacacia L. (콩목: 콩과)에서 채집되었다. 종 동정을 위한 특징과 간략한 기재를 제시하고, 성충과 수컷 및 암컷 생식기의 사진을 제공하였다. 최근 중국에서 양봉업에 매우 중요한 아까시나무의 심각한 해충으로 보고된 바 있어 본 종에 대해 조속한 추가 연구가 필요한 상황이다.

Coniopteryginae is a highly diversified group of Coniopterygidae. In Korea, only two species, Semidalis aleyrodiformis and Conwentzia pineticola, are recorded. Here we report two additional species of Coniopteryginae, Coniopteryx pallescens and Conwentzia sinica, as new records in Korea. Brief descriptions, photos of adults and male genitalia as well as COI barcode sequences are provided.

Conwentzia와 C. pineticola를 한국 미기록속 및 미기록종으로 보고한다. 본 종의 성충에 대한 간략한 기재와 성충 사진 및 생식기 사진과 함께, 16S rRNA 와 COI 염기서열을 제공한다.

가루깍지벌레류인 Pseudococcus viburni Signoret (Hemiptera: Pseudococcidae)는 포도원과 다른 과실 과원에도 피해를 주는 국제적 해충 이다. 이 종은 한국에서 오랫동안 격리되어 왔으며 야외에서의 발생기록은 전혀 없다. 본 연구에서는 한국에서의 P. viburni 부재를 확인하기 위해 전국적으로 감 과수원 533사이트, 사과 및 기타 과수원 144사이트, 묘목원 및 온실 281사이트를 지난 3년간(2015-2017) 조사하였다. 그 결과 P. viburni는 한국의 야외에서나 묘목원 등에서 발생되지 않는 것으로 확인되어 이를 보고한다.

We investigated if Pseudococcus viburni and P. longispinus, the two notorious pest species of mealybugs are foundin Korea. Our survey involved a total of 602 sites all over the country for the last three years. Pseudococcus viburniwas only once referred in Gimpel’s 1983 dissertation on P. affinis group: only one record was noted from Korea amongmany specimens from various countries. However, the species has never been reported from Korea for the last severaldecades and none was found in our thorough survey. We believe there was a misidentification, as noted by the authorregarding the species complex, and conclude that P. viburni does not occur in Korea. On the other hand, P. longispinushas been found in 36 sites, all from imported tropical houseplants in a green house or nurseries. In addition, anothersimilar species has been found from 86 sites. This unknown species was surprisingly best matched with P. orchidicola.Both species could not survive Korea’s harsh winter and they could only survive in a temperature-controlled place suchas nurseries and restaurants.

Berothidae is one of the uncommon group of Neuroptera. The family currently include about 22 genera and 100 species in the world. The genus Isoscelipteron include about 20 species in the world, with the distribution covering Eurasia. Several species of this family are known to be a termite predator during larval stage. We collected Isoscelipteron pectinatum adult, which is a new species record in Korea, which is in fact a new family record as well. Here we provide a brief description, photos of adult and male genitalia, and DNA barcode sequence based the specimen examined.
