Coniopterygidae is the fourth largest group of Neuroptera. There are currently 23 genera and 560 species recorded in the world. They have a tiny-sized body, and their wings are covered with whitish wax powder. In Korea, only one species, Semidalis aleyrodiformis has been recorded in Coniopteryginae. Recently we collected two additional species, each belonging to Spiloconis and Coniocompsa in Aleuropteryginae. In this poster, Spiloconis sexguttata and Coniocompsa postmaculata are newly recorded in Korea. Morphologically Spiloconis sexguttata has reddish colored body with some flagella segments black while Coniocompsa postmaculata has blackish pattern on forewing. We provide brief descriptions, photos of adults and male genitalia and DNA barcode sequences based the specimens examined.

Two species of the genus Herpetogramma Ledere are reported for the first time from Korea: Herpetogramma licarsisalis (Walker) and Herpetogramma stultalis (Walker). The larvae of H. stultalis are well known pest of Achyranthes aspera. Also H. licarsisalis important pest of turf and some other grass crops in Hawaii, Australasia, and Southeast Asia. The description, host plants, adult photographs, and pictures of male and female genitalia are provided.

The genus Saissetia Deplanche is newly reported from Laos, including two new species, Saissetia simulocoffeae Choi & Lee, sp. n. and S. quasioleae Choi & Lee sp. n., and a first record of S. miranda (Cockerell & Parrott, 1899). A key to all five species of Saissetia known from Indochina is provided. The DNA barcodes (mitochondrial cytochrome oxidase subunit I-mtCOI) of the two new species were obtained for future use.

A taxonomic study of Korean species of the geostibine genus Aloconota is presented. The genus is represented in Korea by seven species including five new species, A. brunnea Lee & Ahn, sp. n., A. hydrosmectoides Lee & Ahn, sp. n., A. impressa Lee & Ahn, sp. n., A. parviocularis Lee & Ahn, sp. n. and A. tuberculata Lee & Ahn, sp. n. A key to the Korean species and illustrations of diagnostic characters are provided.

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 Banchinae are a large cosmopolitan subfamily that includes approximately 1,700 species in 65 genera. The number of species in South Korea is still pooly known and only 18 of the 275 Eastern Palaearctic species have been reported. Most species are koinobiont endoparasitoids of Lepidopteran larvae and pupae. A few banchines also parasitize Coleoptera and Hymenoptera. This subfamily is divided into three tribes; Atrophini, Banchini and Glyptini. The former is the largest tribe with 953 species in 40 genera, and is easily distinguished from two other tribes by the tergites without oblique grooves and the nevellus which is intercepted at middle. Cryptopimpla is moderately large genus with worldwide distribution. As a member of tribe Atrophini, Cryptopimpla can be distinguished by follow: Occipital carina connected with hypostomal carina; epomia absent; lower half of mesopleuron weakly convex; ovipositor sheath 0.5-1.0 times as long as hind tibia; ovipositor tip with subapical dorsal notch. Until now the genus was not found in Korean fauna. Here we report four species, two of them are described as new to science. The description is given also for newly reported male of Cryptopimpla brevigena Kuslitzkii and C. carinifacialis Sheng. A key for South Korean species is proposed.

A new species of the cave-dwelling springtail Lethemurus coreanus Chang and Bae, sp. n. is described from Korea. Lethemurus coreanus can be distinguished from congeners by the spinelike setae on the tibiotarsus, numbers of dental spines, number of setae on the trochanteral organ, and body macrochaetae chaetotaxy. A key to the species of Lethemurus is provided.

Two new species of Tanaidacea are described from the eastern coast of Korea; Apseudomorpha n. sp., and Leptochelia n. sp., belonging to the family Metapseudidae and Leptocheliidae, respectively. Apseudomorpha n. sp., is characterized by pleonites 2 and 5 and pleotelson have a large lateral seta; pleopods are biramous, in five pairs, each bearing a two-segmented exopod and a single- segmented endopod; the maxillular palp is two-segmented, with five setae on its distal segment. Leptochelia n. sp., differs from the basis of maxilliped has 4 setae; the uropod exopod is 0.5 to 0.6 times as long as proximal endopod segment and endopod 3 segment is the longest.

The former Scelionidae (sensu stricto) is considered to be a part of Platygastridae, recently. During the parasitic wasp collecting with yellow pan trap, aiming at investigating promising biological control agents which attack on plantbug pests for soybean cultivation, one new species and one unrecorded scelionine species were identified. Opisthacantha albertoi sp. n. was collected from central part of korean peninsula. It is very unique by its yellowish body, compared with the black of the most recorded korean scelonine species. It has a long ovipositor which is 1.3 times longer than body length. It was named after the late Dr. S.-B. Ahn, the noctuid specialist. The unrecorded Tiphodytes gerriphagus (Marchal) was famous for its extremely extraordinary habit of diving for Hymenoptera to attack the eggs of gerrid hosts (Gerris, Trepobates spp.). It was collected nationwidely in Korea. As a result, two genera are newly added in korean scelionine fauna and korean Scelioninae is composed of eight species in five genera in total.

Four new species of the genus Cacopsylla Ossiannilsson are described and illustrated based on adults and fifth instar immatures. Cacopsylla spp. nov. are associated with Malus baccata (L.) Borkh. (Rosaceae), Crataegus pinnatifida Bunge (Rosaceae), Aralia elata (Miq.) Seem. (Araliaceae), Pittosporum tobira (Thunb.) W. T. Aiton (Pittosporaceae) respectively. Short biological notes are provided.

The Lamiine subgenus Pseudale Schwarzer, 1925 from Korean peninsula is reviewed. Along with the only recorded species Pterolophia (Pseudale) jiriensis Danilevsky, 1996, we found two additional new species based on morphological and genital difference. Descriptions, photographs of habitus and male genitalia of each species and a key to species of Korea are provided herein. Hence, genital variation of 4 different geographical populations of Pterolophia (Pseudale) jiriensis is discussed.

Four new species of the genera Masirana Komatsu, 1942 and Longileptoneta n. gen. (Araneae, Leptonetidae) are described from Gyeongsangbuk-do and Chungcheongbuk-do, Korea, under the names Longileptoneta songniensis n. sp., Masirana bonghwaensis n. sp., M. ilweolensis n. sp., and M. flabelli n. sp. A new genus, Longileptoneta n. gen., is also described.

Ten new species of the genus Falcileptoneta are described; Falcileptoneta bifurca n. sp., F. boeunensis n. sp., F. chiakensis n. sp., F. cornuta n. sp., F. digitalis n. sp., F. hansanensis n. sp., F. juwangensis n. sp., F. moakensis n. sp., F. naejangenesis n. sp., and F. unmunensis n. sp. And six species previously known as Leptoneta spiders are transferred to Falcileptoneta as fo11ows; Falcileptoneta coreana (Paik and Namkung, 1969), F. hwanseonensis (Namkung, 1987), F. secula (Namkung, 1987), F. simboggulensis (Paik, 1971), F. yebongsanensis (Kim, Lee and Namkung, 2004), and F. yongdamgulensis (Paik and Namkung, 1969), all n. comb.

The bdelloids collected from various terrestrial habitats such as mosses, lichens, mushrooms on tree trunks, leaf litter and soil at four different locations in Korea were investigated. Five bdelloids new to Korea were identified: Macrotrachella inermis Donner, 1965, Macrotrachela magna Schulte, 1954, Macrotrachela oblita Donner, 1949, Habrotrocha eremita (Bryce, 1894) and Habrotrocha schultei Donner, 1965. All these rotifers except M. inermis are new to Asia as well. Remarkably, these five Korean new records included four rare species with poorly known distributions. M. magna and H. schultei are recorded outside their type localities for the first time. M. oblita has been reported only from five European countries, and M. inermis has been known from three European countries and Eastern Turkey before the present study. The taxonomy and distribution of each rare bdelloid are discussed here.
