Two new species, Joeropsis denticulatus sp. nov. and Joeropsis semicircularis sp. nov. are reported from South Korea. Joeropsis denticulatus sp. nov. differs from its congeners by the following features: (1) whole body has chromatophores dorsally, although those in pereonite V occasionally are faint or lacking according to individuals; (2) lateral margins of the cephalon are smooth and narrowing anteriorly; (3) the distal end of the pseudorostrum is round; (4) maxillipedal palp article II has a mesial lobe bifid distally; and (5) basis of pereopods have serrated cuticular scales superiorly. Joeropsis semicircularis sp. nov. can be distinguishable from other Joeropsis species by the following characteristics: (1) the cephalon, pereonite IV, and pleotelson have dark brown chromatophores dorsally; (2) lateral margins of the cephalon are smooth and parallel each other; (3) the distal end of the pseudorostrum is round and slightly serrate; (4) flagellar article I of the antenna is swollen and semicircular-shaped; and (5) the pleotelson and uropods are serrated on lateral margins.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

Two new species, Cleantiella ampliscutula sp. nov. and Pentias pluriarticulatus sp. nov., are reported from Korean waters with keys to all known species of the genera Cleantiella and Pentias. Cleantiella ampliscutula sp. nov. can be distinguished from its congeners by the following characteristics: the body is relatively small; pereonite 1 is expanded anterolaterally; coxal plates 2–7 are triangular; the pleon has three partial sutures; the pleotelson is widening posteriorly on the lateral margin; the flagellum of the antenna is single-articled; and the maxillipedal palps are four-articled. Pentias pluriarticulatus sp. nov. can be distinguishable from its congeners by the following characteristics: the lateral margins of the body are parallel; the anterior margin of the cephalon is slightly concave and has a small median notch; the coxal plates are invisible dorsally on pereonites 2–4, but visible on pereonites 5–7; the pleon has three partial sutures; the flagellum of the antenna is composed of nine articles; and the distal ends of the uropodal endopods are sinuous.

A New Species

Integrative taxonomy tests the validity of taxa using methods additional to traditional morphology. The existence of two different morphotypes in specimens identified as Chrysotoxum vernale Loew (Diptera: Syrphidae) prompted their taxonomic study using an integrative approach that included morphology, wing and male-surstylus geometric morphometrics, genetic and ecological analyses. As a result, a new species is recognised, Chrysotoxum montanum Nedeljković & Vujić sp. nov., and C. vernale is re-defined. A lectotype and paralectotypes are designated for C. vernale to stabilize this concept. An additional species, Chrysotoxum orthostylum Vujić sp. nov., with distinctive male genitalia is also described. The three species share an antenna with the basoflagellomere shorter than the scape plus pedicel and terga with yellow fasciae not reaching the lateral margins. This study confirms the value of integrative approach for resolving species boundaries.

Two news species of Tricorythodes are described from both, nymph and male imago: Tricorythodes chalaza sp. nov. and Tricorythodes diasae sp. nov. Imagoes of T. diasae sp. nov. can be characterized as follows: vein CuP of wings absent or incomplete; distal 3/4 of hind legs black; inner margins of styliger plate projected; penes rectangular with lateral margins sclerotized, forming two distal lobes inserted apico-dorsally with rounded margins whereas imagoes of T. chalaza sp. nov. present: vein CuP incomplete or absent; inner margins of styliger plate projected; basal swelling on segment II of forceps shaded with black; penes pyramidal with lateral margins sclerotized, divided apically.

A little known tachinid genus, Metadrinomyia Shima, is revised based on four East Asian species including two new to science: M. flavifrons sp. nov. and M. xanthokolos sp. nov. The majority of the specimens used in this study were collected from low vegetation in the foothills of mountains in South Korea. The new species can be clearly distinguished from their congeners by their pruinosity, chaetotaxy and genitalic structures. A key, descriptions, photographs, and illustrations of the male genitalic structures are provided and the phylogenetic relationships among the species are investigated.

Insight Into

Two new planktonic ostracods of the genus Proceroecia Kock, 1992, P. hwanghaensis sp. nov. and P. joseondonghaensis sp. nov., collected from neritic waters off the south coast of South Korea are described. Morphologically, they are similar to P. microprocera (Angel, 1971), the type species of the genus, but show several clear morphological differences, most prominent being the shape of the male endopodite on the second antenna and the presence of a sensilla on the coxale of the fifth limb. The two new species have subtle differences, such as the length of the frontal organ, number of spines on the comb-like e-seta on the first antenna in males, number of spinules on the b-seta on the second antenna in females, etc. Sequences derived from partial mitochondrial cytochrome oxidase c subunit 1 (mtCOI) for these novel species have been compared with sequences available for other Proceroecia species on GenBank, including P. microprocera. These comparisons suggest that both new species are distinct taxa. They also indicate that one set of sequences on GeneBank previously attributed to P. microprocera and derived from material collected from Chinese waters, belong to P. hwanghaensis, and that another set of sequences of an unidentified Proceroecia species from the South China Sea can be attributable to P. joseondonghaensis. Hence, these new species occur widely in the neritic waters of East Asia. The present study increases the number of the known Proceroecia species to nine, and the numbers of halocyprid ostracod species recorded from Korean waters to six.
