The family Erebidae (Lepidoptera: Noctuoidea) is known as one of the largest families in Lepidoptera, comprising about 1,760 genera and more than 24,569 described species worldwide. Within this family, the genus Plecoptera Guenée, 1852, belonging to the subfamily Anobinae, has been documented across the Palaearctic, Oriental, and Afrotropical regions. Here, we introduce the subfamily and genus for the first time in Korea, along with a new species. The diagnosis, description and photographs of adult and genitalia are provided here.

The community temperature index (CTI) reflects the temperature and environmental preferences of the community. We investigated the distribution patterns of major aquatic insect assemblages (Ephemeroptera, Plecoptera, and Trichoptera; EPT) based on CTI in streams of South Korea. We selected unpolluted 151 study sites at upper streams (less than 3rd) with less than 1.5 mg L-1 of biochemical oxygen demand. Study sites were clustered into six groups based on the similarities of their EPT composition. All three orders showed a continuous decrease in the number of species as CTI increased, especially in Plecoptera. In addition, the functional feeding groups were also significantly changed according the CTI changes. Temperature tolerance range of each group’s indicator species varied according to the CTI of the group. Finally, changes of CTI reflected differences of EPT assemblages according to the differences of environmental condition including temperature. Therefore, CTI can be applied to the evaluation and preservation of stream ecosystems and prediction of community changes due to climate change.

최근 보령 지역의 후기 트라이아스기 아미산층에서 다량의 화석 강도래 유충이 발견되었다. 이들의 유충은 그 형태적 특징에 의해 Platyperlidae과, Baleyopterygidae과, Siberioperlidae과 등으로 분류되었다. 이 중 양적으로 가장 많 이 발견되는 종류는 Baleyopterygidae과의 화석 강도래이다. 이러한 사실은 강도래가 러시아, 몽골 및 중국을 비롯한 동 북아시아 지역까지 이미 중생대부터 넓게 분포했음을 의미한다. 현생 강도래는 대부분 유수성이며 맑은 물에 서식하기 때문에 화석 강도래가 발견되는 보령 지역도 유사한 환경이었을 것으로 추정된다. 또한 강도래와 함께 발견되는 화석들 로 미루어 볼 때 당시의 강도래는 하루살이나 패갑류 등을 먹고 살았던 것으로 추정된다.

Life cycles of Sweltsa illiesi and S. lepnevae were determined from a headwater stream in Mt. Jumbong. Identification of nymphs was done by using DNA barcoding. Nymphs begin to have species specific color pattern on their head several months prior to adult emergence and differ in the form of the third antennal segment. Two species appear to have similar semivoltine life cycles in this stream, beginning to hatch from June and finishing adult emergence about 701 days later. The combined annual mean biomass in ash free dry mass (AFDM) was estimated as 96 mg AFDM m-2. The combined annual secondary production were 373 mg and 297 mg AFDM m-2 yr-1, calculated by using size frequency method and increment summation method respectively.

한국산 강도래목의 연구는 1921년에 시작되어 1980년대 이후부터 최근 20년간 연구가 가장 활발하였고.과별로 종수는 Nemouridae가 가장 많고, 다음이 Chloroperlidae였다. 한편 북한산 강도래목의 연구는 1938년에 시작되었고, 외국인에 의해 1970년대에 많은 진전이 있었고, 그 이후 적은 수의 종들이 추가적으로 보고되고 있으며, 과별 종수를 보았을 때 Perlidae가 가장 많고, 다음이 Nemouridae였다. 한국산 강도래목은

Two species of peltoperlid stonefly nymphs, Cryptoperla bisaeta (Kawai) and Cryptoperla sp. 1 (Plecoptera, Peltoperlidae), are described from Vietnam. Their descriptions, diagnoses, photographs, and taxonomic remarks are provided.
