The Genus Psectra is a small group of Hemerobiidae, and Psectra diptera is one of the rare and attractive species in this group because of hindwing variation. They are well known to have their hindwing reduced, similar to flies, depending on their habitat environment. We report Genus Psectra and Psectra diptera, new records from Korea. We provide brief descriptions and photos of adults and genitalia.

Hemerobius contumax Tjeder, 1932 is a well known species of Hemerobiidae (Neuroptera) in Europe and Middle East countries, but has never been found in Asia. In Korea, a total of eight hemerobiid species have been recorded including the genus Hemerobius. So far only two species, Hemerobius humulinus and Hemerobius harmandinus are reported. Recently we collected another species of which the specific identity is in question: morphologically very similar to Hemerobius contumax but with c.a. 5% difference in COI barcode sequences. With 5% genetic difference, it may be easily considered as a different species from H. contumax. However, the adult image from the specimen sequenced for H. contumax found in the BOLD site is morphologically slightly off from the usual H. contumax, and there is still an investigation needed to confirm its specific identity. In any case, here we provide a brief description, photos of adult and male genitalia and DNA barcode sequence based the specimen examined.

The Genus Drepanepteryx Leach, 1815 and Drepanepteryx phalaenoides (Linné), 1758 (Neuroptera:Hemerobiidae) are newly reported to Korea. Only one species, Neuronema albostigma have been reported in Korea as a species of Drepanepteryginae. In this study we report another species, Drepanepteryx phalaenoides and provide photos of adult and male genitalia based the specimen examined.

본 연구는 온도(15, 20, 25, 30℃), 습도(70 ± 10%), 광주기(16L:8D)에서 갈고리뱀잠자리붙이의 생물적 특성을 조사하기 위해 수행되었다. 알에서부터 번데기까지의 발육영점온도 및 유효적산온도는 각각 9.6℃ 및 270.3일도였다. 25℃에서 갈고리뱀잠자리붙이의 알 기간은 4.4일, 유충은 5.5일, 번데기는 6.9일이었다. 암컷 성충의 수명은 34.9일, 산란 기간은 28.7일이었고, 총 산란수는 515.2개, 1일 최대 산란수는 54.8개였다. 25℃에서 갈고리뱀잠자리붙이에 의한 싸리수염진딧물의 1령, 2령, 3령 및 성충의 일일 포식량은 각각 18.9, 47.2, 57.7 및 91.0마리이었다. 따라서 갈고리뱀잠자리붙이는 진딧물의 포식성 천적으로 이용이 가능할 것으로 여겨진다.

Micromus variegatus (Neuroptera: Hemerobiidae) is reported here as new to South Korea. In addition, three other hemerobiid species recorded only the collection data, Hemerobius harmandinus, Sympherobius tessellatus and S. domesticus are also reported with a brief description, images of the adult and wings, and its Korean common name. With four previously reported species in Korea, there are eight species of the family Hemerobiidae from Korea.

Study of the Korean Hemerobiidae has been so scarce that only three species in two genera were recorded in Korea. Here we report an undescribed species, Micromus angulatus, new to Korea. A brief description and images of the wing pattern, and adult and genitalia of both sexes are provided.

The genus Micromus is a large group, belongs to the family Hemerobiidae with a worldwide distribution. This genus was named by Rambur, 1842 based on the type species Hemerobius variegates Fabricius, 1793. Eighty five species have been described from the world. Among them only one species, M. numerosus (Navás), has been recorded from Korea. Morphologically, Micromus is easily distinguished from other hemerobiid genera by the combination of the following characteristics: maxillary palpus 5 segments, labial palpus 3segments; forewing with costal area quite narrow at base and one prestigmal Sc-R crossvein, without recurrent humeral vein and crossvein 2M-Cu. Members of the genus Micromus are generally considered to be beneficial as predators of various aphids, particularly on sugar cane and corn plants. This genus occurs in a variety of habitats including both trees and grasses. It is often found in alfalfa fields where both larvae and adults feed on aphids. Adults are also highly attracted to lights at night. In this reviewing study about the Korean Micromus, we study two species. M. angulatus (Stephens) and M. numerosus (Navás). Among them M. angulatus is newly included in Korean fauna. We also provide a key to the Korean species of Micromus, description, illustrations of diagnostic characters and distributional data.

Study of the Korean Hemerobiidae has been so scarce that only three species in two genera were recorded in the list of insects in Korea (1994). Here we report two undescribed species, Hemerobius harmandinus and Micromus variegatus, new to Korea. Descriptions and images of the adults and their genitalia are provided.
