As a result of an ongoing systematic study of the genus Phasia Latreille in Korea, we have discovered P. aurigera and P. takanoi for the first time in Korea. We here provide detailed redescriptions and illustrations with their diagnostic characters indicated. Phasia aurigera can be distinguished from other congeners by the combination of the following characteristics: 1) scutum with distinct yellow pruinose spot; 2) male abdominal tergite 5 posteromarginally with V-shaped yellow pruinosity; 3) distiphallus divided into anterior and posterior processes; 4) female sternite 7 short, as long as or slightly longer than sternite 6 (visible part); and 5) female sternite 8 (ovipositor) bent dorsally. Phasia takanoi can also be distinguished by the combination of the following characteristics: 1) abdominal tergites strongly shiny; 2) surstylus strongly bent upward; and 3) posterior margin of female sternite 7 straight in ventral view.

In Korea, species of the genus Ptecticus Loew, 1855 (Family Stratiomyidae) have been known as three species, P. aurifer (Walker, 1854), P. matsumurae Lindner, 1936 and P. japonicus (Thunberg, 1789) (= P. tenebrifer (Walker, 1849)). Additionally, an unrecorded species, P. sinchangensis ${\hat{O}}uchi$, 1938, was found in Korea. We therefore report the species for the first time in Korea with morphological diagnosis and key for the identification of the Korean species of the genus. In total, the members of the genus Ptecticus are officially recognized as four species in Korea.

Mycophagous gall midges in the family Cecidomyiidae (Diptera) are poorly known in Korea, with only 14 recorded species. From our sampling throughout South Korea during 2015-2017, we present evidence of the Korean distribution of another 20 species as follows-Lestremiinae: Anarete angusta Mo & Xu, 2009; Micromyinae: Anodontoceras saigusai Yukawa, 1967, Campylomyza appendiculata Jaschhof, 2015, Campylomyza furva Edwards, 1938, Peromyia gotohi Jaschhof, 2001, Peromyia pumila Jaschhof, 2001, and Tekomyia populi Möhn, 1960; Winnertziinae: Leptosyna nervosa (Winnertz), 1852, Winnertzia nigripennis (Kieffer), 1894, and Winnertzia solidaginis Felt, 1907; Porricondylinae: Bryocrypta indubitata Mamaev, 1964, Camptomyia flavocinerea Panelius, 1965, Coccopsilis obscura (Mamaev), 1964, Coccopsilis paneliusi (Yukawa), 1971, Cryptoneurus muscicola (Kieffer), 1896, Dirhiza abludentis(Mamaev), 1998, Divellepidosis separata (Yukawa), 1971, Larimyia lavalis Fedotova & Sidorenko, 2007, Parvovirga latostylata Jaschhof, 2013, and Porricondyla nigripennis(Meigen), 1830.

Members of this family Sciomyzidae are known as marsh flies and snail-killing flies because most of the known larvae are obligate predators of Mollusca, especially freshwater and terrestrial Gastropoda. Most species are found in the shallow ephemeral aquatic habitats with rich organic substrates, such as the hard-water streams, small ponds and lakes in mountain valleys. To date, a total of 8 marsh fly species in 4 genera have been known in Korea. During a taxonomic survey of the family Sciomyzidae in Korea, the authors have found the genus Ditaeniella Sack, 1939; thus, it was discovered for the first time in Korea. This genus can be distinguished by the other related taxa with hairs over much of the mesopleuri, hairs on the prosternum and one orbital seta. In addition, the nominate species, Ditaeniella grisescens Meigen, 1830 was also firstly recoded in the Korean fauna.

The genus Parorthocladius is a small group among the subfamily Orthocladiinae (Diptera: Chironomidae). A total of ten species of Parorthocladius have been recorded in the world, of which two species were found from Japan, three species from China, and three species from the Russian Far East. Only one species, P. nudipennis is widely distributed in Europe and the Russian Far East. This genus can be distinguished from other genera by the absence of acrostichals on the thorax, wing vein R4+5 ending proximal to the tip of vein M3+4, anal point parallel side, rounded apically. We report four new species of Parorthocladius collected in Korea and described them with illustrations. As a result, fourteen species of Parorthocladius have been recorded in the world.

Three species of the genus Dohrniphora, viz., D. cornuta, D. malaysiae, and D. prescherweberae were newly recorded from Korea. These newly recorded species can be easily identified by the characteristic that inner face of male hind femur equipped with a group of peg-like stout setae on basal sensory area. Peg-like setae are arranged perpendicularly in D. cornuta whereas linear in D. malaysiae and somewhat arched in D. prescherweberae. Also, concave area near the peg-like setae is also well developed in male which is smooth in D. cornuta, on the other hand, there is well developed distal carina in D. malaysiae and with groups of microtrichia in D. prescherweberae. In this study, detailed descriptions with photographs of three newly recorded species and a key to males of all Korean Dohrniphora species are provided.

The family Chamaemyiidae is commonly referred to as aphid flies, as all larvae are predators of sternorrhynchous aphidoid or coccoid hemiptera, as well as a small group of acalyptratae flies found worldwide. Adults are small flies and typically found near their larval prey in grasslands and forests. They have a silver-gray body with dark gray or black markings on the abdominal tergites. This family is described for the first time in the Korean fauna, based on the discovery of two nominated species: Leucopis argentata and Leucopis glyphinivora. Diagnoses and figures about the firstly recorded species, and a key to the Korean species are provided herein.

The genus Dichaeta Megen is a small group of acalyptratae flies belonging to the subfamily Notiphilinae in the family Ephydridae. Up to now, six species are recorded only in the Northern Hemisphere. Adults are small flies and typically found in the sedge and grass around lentic and lotic aquatic systems, and larvae feed on saprophytic microorganisms. Adults are readily recognized with the following peculiar morphology of the male abdomen: fourth abdominal tegite with some markedly long setae along its posterior margin, and these setae sometimes extend beyond the length of the posterior apex of the abdomen; modified fifth abdominal tergite produced posteriorly, either forming a slender and elongated tube with two to three larger and elongated terminal setae. This genus is recorded for the first time in the Korean fauna based on the discovery of a nominated species, Dichaeta caudata (Fallén, 1813). Diagnoses and figures about the firstly recorded species are provided herein.

Chironomus is a large genus of Diptera comprising about 400 species and occurs worldwide except for Antarctica. The strong morphological cross-taxon similarity of chironomid larvae renders identification at the species level difficult. Here, we analyzed the morphology of larvae of Chironomus flaviplumus, an easily cultured species employed as a bioindicator in polluted environments, to determine identifying morphological characteristics at the first through fourth instar. Observed differences appearing at each instar include the presence or absence of setae on the body and tubules on the 10^th and 11^th body segment, the number of seta interna in the mandible, and the presence or absence of ring organs in the antennae. Some specific morphological characteristics did not change after hatching. Our findings provide a reliable method for identifying C. flaviplumus larvae.
