The family Pyralidae comprises over 6,000 species, and is composed of five subfamilies. Among those, the subfamily Phycitinae includes 3 genera, Addyme Walker, 1863, Calguia Walker, 1863, and Coleothrix Ragonot, 1888, with more than 3,300 species worldwide. However, several species of the genera have been erroneously stated and identified due to confusions caused by high morphological similarities. Therefore, we correct those errors through re-examinations of most of the type specimens, along with a diagnosis and table exhibiting the history of those genera. Additionally, we introduce two misidentified Korean pyralids belonging to the genus Addyme.

Chironomids are a large group of invertebrates that live in various aquatic habitats. The distribution range of these invertebrates has become varied due to anthropogenic impacts; as such, their distribution can be used as an indicator of environmental health. Adult chironomids are well known in South Korea; however, the larvae have rarely been studied due to difficulties associated with morphological classification. To address this lack of information, we collected larvae from four important rivers in South Korea and summarized their taxonomic morphological characteristics. The antennae, mandible, and mentum were used for larval taxonomic characterization. In this study, we describe the basic morphological features and key pictorial features of 20 species of chironomids, representing 16 genera.

Epyris Westwood, 1832 is the largest genus of Bethylidae with more than 300 nominal species and 19 species of Epyris have been recorded in Korea. The Epyris species are small to medium sized (2–10 mm) wasps with the palpal formula 6:3; the median lateral clypeal lobe reduced; pronotum usually longer than wide; notauli and parapsidal furrows present; scutellar pits not connected by a groove; basal vein of the fore wing arising almost at apex of subcostal vein. As results of taxonomic studies on Korean bethylids, Epyris emiae Terayama, a brachypterous species, is first discovered from South Korea. In this presentation, a diagnosis, figures of diagnostic characteristics of E. emiae are provided with a discussion on forewing veins of Korean bethylid genera.

A research probing for the unrecorded and taxonomically undescribed indigenous species has been initiated since 2006. Samples were collected from an intertidal zone along the coasts of Korea as well as around the Jeju Island. We have found five unrecorded species of four genera belonging to the order Dinophysiales, Gymnodiniales, Peridiniales, and Prorocentrales. The species are as follows, Sinophysis canaliculata (2017) Bispinodinium angelaceum (2015), Cabra armorica (2016), Prorocentrum bimaculatum (2017), and P. tsawwassenense (2017) (note; The numbers in parenthesis refer to the year in which the species was reported as unrecorded indigenous species by National Institute of Biological Resources, NIBR hereafter).

개미사돈아과는 반날개과에서 두 번째로 큰 분류군이지만 다른 아과에 비해 연구가 가장 미흡한 분류군 중 하나이다. 개미사돈아과 내 다른 모든 아과의 자매군인 Faronitae상족은 비교적 작은 상족이며 최근 뉴질랜드 지역에서 종 수준의 포괄적인 재검토가 이루어졌다. 이를 바탕으로 Faronitae상족의 12속을 좀 더 쉽고 빠르게 동정하기 위하여 이미지를 활용한 interactive 분류키를 작성하였다. 분류키는 Lucid 3.3 builder를 사용하여 제작하였으며 총 36개의 형질과 134개의 형질상태를 사용하여 작성되었다. 이 프로그램은 현재 세계적으로 다양한 분야에서 사용되고 있는 식별키 프로그램이며, 제작 후 배포에도 용이하여 다른 연구자들에게도 정보를 제공할 수 있다. 이번 연구에서 포함된 속은 현재 뉴질랜드에 알려진 모든 속을 포함한다. 본 연구를 통하여 Faronitae상족에 대한 정보들을 제공하고, 웹 기반의 다양한 활용이 기대된다.

An investigation focusing on the unrecorded and taxonomically undescribed indigenous has been done since 2006. Samples were collected from various sites in the coastal and offshore waters of Korea as well as around Jeju Island. Since 2008, 16 unrecorded species belonging to the family Gymnodiniaceae have been found. The species were as follows: Amphidinium thermaeum (2015), Cochlodinium convolutum (2015), C. strangulatum (2015), Gymnodinium abbreviatum (valid name: G. gracile), G. arenicola (2015), G. gracile (2015), G. dorsalisulcum (2015), G. microreticulatum (2014), G. micrum (2016) (valid name: Karlodinium micrum), G. pyrenoidosum (2016), G. simplex (2015), G. veneficum (2016) (valid name: Karlodinium veneficum), Gyrodinium aureum (2015), G. fusiforme (2015), G. dominans (2014), and Nusuttodinium latum (2016) (valid name: Amphidinium latum). (The numbers in parentheses refer to the year that the species was found). These species were newly recorded in Korean waters in this study.

The order Prorocentales currently includes two genera Prorocentrum Ehrenberg and Mesoporos Lillick. The Prorocentrum genus is a predominant group throughout the year found in Korean waters. To date, the Prorocentrum genus includes 31 species and the Mesoporos genus has only one species in Korean waters. In this study, we identified one Mesoporos species and three Prorocentrum species around a coast of Jeju Island, and described them as newly recorded species in Korean waters.
