We found a new recorded species, Drosophila subpulchrella Takamori & Watabe from Dopyeong-ri, Idong-myeon, Pocheon-si, Gyeonggi-province. The species of the D. suzukii subgroup in the D. melanogaster species group is reported from Japan and southern China up to now. This species is morphologically very similar to D. suzukii: with spots on the tip of fore-wing(male) and serrated ovipositor(female). The goals of this study are to add a new recorded species, D. subpulchrella to Korean fauna and provide the biological references such as morphological and molecular data using for the species identification

Adult and genitalia of male is described, with illustrations.

Anastatus orientalis Yang & Choi, 2015 (Hymenoptera: Eulpelmidae) is reported for the first time from Korea. It is a solitary endo-parasitoid in egg of Licorma delicatula (Hemiptera: Fulgoridae), Which causes damages to many ornamental and fruit trees in Korea. This species would be a good biological agent for suppression of the spotted lanternfly in Korea. More than 40 specimens of this species were collected in Cheonhyeon-dong, Hanam-city and Samsung-dong, Seoul city. This Korea species was compare with that from China in morphlogical characteristics and barcodes region of COI.

A genus Daptus Fischer von Waldheim, 1823 of the tribe Harpalini Bonelli, 1810 (Coleoptera: Carabidae) is recorded for the first time in the Korea, based on D. vittatus Fischer von Waldheim. A redescription, illustrations of diagnostic characteristics including genitalia of both sexes, and a key to Korean genus of the tribe are provided.

The genus Miaenia Pascoe, 1864 (Coleoptera Cerambycidae) in Korea is taxonomically reviewed in this study. Miaenia was erected by Pascoe (1864) based on the type species M. marmore. Miaenia has been accepted as a subgenus of Sciades for a long time, howerer, Roguet (2012) considered Sciades as a synonym of the genus Miaenia. Previously, two species, M. fasciata fasciata (Matsushita, 1943) and M. maritima Tsherepanov, 1979, of the genus have been reported in South Korea. In this paper, M. tonsa (Bates) is recorded in Korea for the first time. A key to the Korean Miaenia species, diagnoses, illustrations of diagnostic including male genitalia are provided.

A predatory genus Cryptalaus Ôhira, 1967 (Coleoptera: Elateridae) in Korea is taxonomically reviewed in this study. Up to date, two species of the genus Cryptalaus, C. berus Candèze, 1865 and C. larvatus pini Lewis, 1894, have been reported from Korea. From the present study, C. yamato Nakane, 1957 which has been regarded as an endemic to Japan, is reported from the Korean peninsula for the first time. A key to the Korean species of the genus Cryptalaus, diagnosis, illustrations of diagnostic characteristics are provided.

The family Scelionidae is distributed all around the world, which has approximately 3,000 species within 150 genera in the world. To date 39 species of 15 genera from 3 subfamilies in Scelionidae are recorded in South Korea. In this study, we report a new record of the genus Idiris with one species. There are many parasitory and predatory insects specializing on spider eggs. Among scelionids, some species (Baeus achaearneus, Comastichus zopheros, Idris sp.) parasitize spider eggs. However, there was no Korean record for scelionid wasps parasitizing in egg sacs of spider. Based on morphology, ecology, and DNA identification, we recognized this species, Idris sp., being new to Korea. All examined specimens and DNA samples are deposited in Kunsan National University.

The genus Toxares (Braconidae: Aphidiinae) is reported for the first time in Korea. Members of Toxares are known as solitary koinobiont endoparasitoids especially specific for aphidine aphids. In this study, Toxares deltiger (Haliday, 1833) is found as new to Korea, which has a wide host range for 31 aphid species within Aphidinae. Thus, this species would be useful as natural enemy for biological control in the future. Diagnosis and host information are included.

A newly recorded glycerid polychaete collected from mud of the tidal flat in the southwestern coast of Korea is identified as Glycera fallax Quatrefages, 1850 based on the morphologies of papaillae and ailerons on proboscis, parapodial postsetal lobes, and branchiae. In this paper, we provide a detailed description and illustration of Korean materials of this species and a key to the species of the genus Glycera from Korean waters.

A sea urchin was collected from 140 m deep at Gapado which is nearby Moseulpo in Jejudo Island, Korea on 30 June 2010. This specimen was classified as Echinolampas koreana H.L. Clark 1925, belonging to family Echinolampadidae of order Echinolampadoida based on its morphological characteristics. This order and lower categories are newly recorded from Korea. Distinct morphological characters of this species are as follows: test is relatively high. Abactical system has four large genital pores. Periproct is slightly sunken and situated below equator line. Peristome is very small and rather deeply sunken. Tridentate and ophiocephalous pedicellariae are present. Color in alcohol is light purple. These morphological characters are re-described with illustrations.

A new species of the genus Ebrechtella Dahl, Ebrechtella juwangensis n. sp. and the male of Ozyptila geumoensis Seo and Sohn, 1997 are reported new to science. Ozyptila utotchkini Marusik, 1990 is reported for the first time in Korea. Habitus photos and illustrations of these three species are provided.

Rhyparini is one of the tribes of well-known termitophilous scarabs included in Aphodiinae Leach, 1815. Several species of the tribe are known to live in association with termites, with both organisms occurring together in relatively large numbers. In extant numbers of this tribe, the larvae live inside termite nests. The tribe Rhyparini can be distinguished by the following combination of characters: clypeus usually bidentate though sometime feebly so, inflexed edge medially obtusely angulate; frons and vertex with tufts of setae or longitudinal tubercles; pronotum with six longitudinal costae equally spaced in at least posterior half of disc, lateral pronotal edge at least feebly bilobed in anterior half; elytra costae, costae varying on height, number and spacing, elytral apices frequently bulbous, epipleura narrow; posterior prosternal process hastate; antenna 9th segmented, club 3th segmented, segments of club short and compact. The tribe includes 77 species of 12 genera worldwide, and Pittino (2006) published a key to world genera in the subfamily Rhyparinae (tribe Rhyparini). In total, nine species of two genera in the tribe Rhyparini have been recorded in the Palaearctic region up to date: Rhyparus Westwood with eight species and Sybacodes Fairmaire one species, In Japan three species are known, China with one and Taiwan five. However, up to date, any has not been reported in Korea. In the present study we report on the tribe Rhyparini from Korea for the first time, based on Rhyparus azumaiazumai Nakane, 1956. Diagnosis and illustrations of detailed diagnostic characters, including male genitalia are provided.

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.
