A poorly known spider, Pholcus kwangkyosanensis Kim & Park, 2009 is redescribed with diagnosis, detailed descriptions, and taxonomic photographs of diagnostic characters. P. kwangkyosanensis is similar in appearance to P. kwanaksanensis Namkung & Kim, 1990, in terms of the shape of the genital organ and body, but it can be easily distinguished from the latter by the shape of the cheliceral apophysis, uncus, and procursus in males, as well as the shape of the epigynum and pore plates in females. The specimens of this spider were collected at the type locality (Mt. Gwanggyosan, Suwon), specifically under the bridge on a local stream in an agricultural landscape surrounded by rice fields, upland fields, or horticultural greenhouses.

Necrophila (Calosilpha) brunnicollis brunnicollis (Kraatz, 1877) is a common necrophagous beetle in the Palaearctic region. The species is often encountered on the corpses of large vertebrates, such as human and pig, and is well recognized as a potentially group of beetles in forensic entomology. All of the developmental stages can be found in the corpse and under the soil near a corpse, which can be used to reconstruct the site, such as estimating PMI(Postmortem interval). However, its larval instar stages were never thoroughly described for identification. In this study, we redescribe the morphological characters of all larval stages of N. brunnicollis for quantitative and qualitative morphological information. In addition, we provide the images of larvae and an indentrifiaction key to larval instars.

During a recent study to understand an interaction of Collembola community and their environmental factors, two species in the genus Folsomia, F. quadrioculata Tullberg 1871 and F. octoculata Handschin 1925, were found in the forest of South Korea. From 2013 to 2015, these two species were sampled from six mountains and F. quadrioculata or F. octoculata was the dominant species in 5 sampling sites among 6 sampling sites. F. quadriocualta and F. octoculata were found in litter of deciduous and pine forest, respectively. Therefore, the major tree species seems to be one of the important factors determining their habitat. F. quadiroculata is newly recorded from the Korean Peninsula and F. octoculata is redescribed based on new materials from South Korea.

Two species of the minuta-subgroup within the oncaeid copepod genus Triconia Böttger-Schnack, 1999 collected in the equatorial Pacific Ocean are newly recorded. A female T. minuta (Giesbrecht, 1893 [“1892”]) and both male and female T. umerus (Böttger-Schnack and Boxshall, 1990) from the northeast equatorial Pacific are redescribed with the comparison of its morphological details, which differs from previous studies, in terms of the larger body size, the length to width ratio of the genital double-somite, the relative length of the outer basal seta on P5, and the ornamentation of the appendages. The characters, which are used for identification, such as the length ratio of the outer subdistal and outer spine versus the distal spine on P3-P4, and the outer spine length of the middle exopodal segment on P3 and P4 are reported for the first time. Information on the variations in the endopodal spine lengths of swimming legs 2-4 is also provided for T. minuta and T. umerus, with the summary of the wide zoogeographical distribution of these two species.

The genus Phyllocnistis belongs to the family Gracillariidae including 85 described species in the world (De Prins and De Prins 2005). The genus has been placed under the family Phyllocnistidae, which is now the subfamily of the family Gracillariidae. In Korea, only one species of the family, Phyllocnistis citrella Stainton has been listed for the first time by Ko (1969) without the taxonomic information. It was first reported by Heppner (1993) from North America, and it has become to the major pest of Rutaceae, especially damaging on the genus Citrus spp. It has been called as CLM (citrus leafminer) in the world. This study was carried out to identify and monitor CLM easily and correctly with providing the genitalic structures and DNA barcode which is now one of the major insect pest on citrus farm.

개맥문동(Liriope spicata (Thunb.))이 검정주머니나방(Mahasena aurea (Butler))의 새로운 기주식물로 처음으로 확인되었기에 보고한다. 또한 본 연구를 통해 본 종의 유충과 암컷이 우리나라에서는 처음으로 채집되었다. 이들의 암컷과 수컷에 대한 외부형태적 특징을 재기재함과 동시에 수컷생식기, 성충, 애벌레, 번데기 등의 특징을 도해하여 제시하였다.

The genus Halectinosoma Vervoort, 1962 is first reported from Korean waters by the discovery of H. perforatum Itô, 1981. This species, previously recorded only from Japan, is collected from the sandy beach on the south coast of Korea, and is well distinguished from other congeners by the combination of following morphological characteristics: the elongate caudal ramus; the remarkably bilobated exopod of female P5; the small innermost seta on the distal margin of female P5 exopod; the presence of three setae on the distal exopodal segment in P4; and the presence of scale-like spinules on the ventral surfaces of urosomite. We herein provide detailed description and illustrations of this species.

Cynegetis impunctata (Linnaeus, 1767), a phytophagous lady beetle, was recorded in South Korea for the first time recently. Previously, only the adult form of this species had been described. In this study, we provide a redescription of the adult and the first descriptions of the larva and pupa. Diagnostic characters for this species are given, and intraspecific color variation in Cynegetis impunctata adults is discussed.

Taxonomic history of Korean Arctiidae was recently revised by Park (2000), comprising a total of 59 species, 31 genera from South Korea. Subsequently, Choi (2004, 2010) added two more arctiine species, and Bae et al. (2013) enumerated 63 species, 31 genera including one unrecorded species, and Lee et al. (2014) reported one more lithosiine species from South Korea. In the present study, we report and confirmone rare species, Spilarctia robusta (Leech, 1899), which has been reported by Nam (1985) from Jeju Is., but it has been omitted from the Check List of Insects from Korea (1994), due to that no specieman has been collected after Nam (1985). We found this species from the collection of the Korea National Arboretum (2012), and redescribed with illustrations of genitalic structure. Therefore 65 species of Arctiinae are known to the fauna of Arctiinae from South Korea.

 ,  , Synanthedon velox (Fixsen) is redescribed and the genus Bembecia is reported for the first time from Korea with B. pavicevia Tosevski, Description, images of the adult, genitalia, and the Korean common names of two species are provided. Their host plants are listed and their biology is briefly summarized.

During the survey of plant parasitic nematode of Citrus orchard in Korea, Paratrichodorus minor (Colbran, 1956) Siddiqi is founded from the soil of Citrus unshiu Markovich for the first time in Korea. The body length of females is 428.34~506.22 ㎛ long: a = 12.08~22.79, b = 4.02~5.02, V(%) = 38.46~60.68. The excretory pore is located near the base of esophagus. Additionally, the morphological characteristics on P. porosus (Allen, 1957) Siddiqi, 1974 recorded in 1976 on Korea is redescribed in detail.

Mormonilla phasma is redescribed, based on the specimens from the Northeastern Pacific. M. phasma in the study area has the following morphological characteristics; second endopodal segment of mandible partly fused to basis and a distinct three-segmented

Jassa slatteryi was redescribed as a new record to Korean fauna, accompanied by the morphological account in comparison with Jassa falcata Montagu, 1808. This work was based on the specimens which were collected from the screw of the international trade s
