A taxonomic study on the freshwater harpacticoids of the genus Attheyella has been accomplished as one of the serial researches on the family Canthocamptidae in South Korea. As a result, a total of seven species belonging to Attheyella are listed, three of which are new to Korean fauna: A. crassa (Sars), A. nakaii (Brehm), and A. orientalis Chappuis. A key to the species of the genus Attheyella known from Korea is prepared.

Genera Mesochra and Elaphoidella have been studied as one of the serial studies on the taxonomy of the family Canthocamptidae in South Korea. As a result of it, two species of Mesochra and three species of Elapholidella are added to Korean fauna: M. alaskana Wilson, M. suifunensis Borutskii, E. grandidieri (Guerne and Richard), E. bidens (Schmeil) and E. superpedalis Shen and Tai. A key to the species of the genera Mesochra and Elaphoidella known from Korea is prepared.

Two new species belonging to the genus Attheyella of Canthocamptidae, collected from two springs each of Mt. Hambak and Mt. Halla of South Korea, are described under the name of Attheyella(Attheyella) paucisetosa and Attheyella(Mrazekiella) byblis, respectively.

Five freshwater harpacticoid species of the genus Bryocamptus are identified as one of the serial taxonomic studies on the family Canthocamptidae in South Korea: B, zschokkei caucasicus (Borutzky, 1930), B. nivalis (Willey, 1925), B, pacificus Ishida, 1992, B. vejdovskyi (Mrazek, 1893) and B. umiatensis Wilson, 1958. Bryocamptus pacificus, B. vedjovskyi and B. umiatensis are newly known from Korea. A key to the species of the genus Bryocamptus in Korea is provided.

Four harpacticoid species belonging to genus Attheyella were confirmed from South Korea: Attheyella (Attheyella) coream Miura, A. (A.) paucisetosa Chang and Kim, A. (Mrazekiella) byblis Chang and Kin, and A. (M.) tetraspinosa, n. sp. The new species and the male of A. (A.) paucisetosa are described. A. (M.) tetraspinosa, n. sp. most resembles A. baikalensis Borutzky, but readily distinguished from it and its relatives by the extraordinarily elongated leg 5 exopod and the female leg 5 basipod bearing four spines on it.

A new copepod species, Cletocamptus koreanus, is described from estuaries and salt marshes on south and southwest coasts in Korea. Cletocamptus koreanus n. sp. evidently belongs to C. deitersi species group in sharing 6-segmented antennule, 3 setae on antennary exopod, leg 1 with endopod shorter than exopod, and 2+1 inner setae on the third exopodal segments of legs 3-4. However, C. koreanus is distinguished from its allied congeneric species by different setal armatures of mandibular palp, antennary exopod, endopod of female leg 2 and the third exopodal segments of legs 3-4, and relative length and shape of apophysis of male leg 3 enp 2. Description and taxonomic accounts of the new species are presented herein, with detailed illustrations and scanning electron microscope photomicrographs. Discussion on the affinities with other species of C. deitersi group are provided, along with brief comments on the morphological discrepancies between the new species from Korea and other Asian species from China and India.

Material of a Bryocamptus species, formerly reported as B. umiatensis Wilson, 1958 from Sakhalin and South Korea, is here recognized as a distinct new species. Specimens of both sexes were recently obtained from an alpine wetland, Sumeunmulbaengdui, located in the Hallasan National Park, Korea, and newly registered as a Ramsar Wetland in 2015. The new species, B. jejuensis n. sp., differs from the type population of B. umiatensis from Alaska by the smooth margin of the anal operculum in both sexes, the peculiarly modified terminal seta on the distal endopodal segment of the male leg 3, the sword-like spinous seta on the distal endopodal segment of the male leg 4, and the presence of a setule row on the inner distal margin of the caudal rami in the female. Both sexes of the new species are described in detail with particular reference to the male characters. A revised key to the seven species of the genus Bryocamptus Chappuis, 1929 occurring in Korean waters is provided.

Conthocamptus mirabilis Sterba is redescribed on the basis of the material newly collected from the type locality near Bekijing, China, with an evaluation of the variability of several characters. C. mirabilis possesses the plesiomorphic characters of the round and narrow hyaline membrane and the unmodified outer terminal furcal setae, while it also bears the apomorphic ones of the male-type caudal rami in females and the modified outer terminal setae of male leg 4 exopod. the peculiar dorsal keel ornamented with spinule array on the female's caudal rami is the most significant feature differentiating this species from its relatives of the mirabilis group, which turned out to be a species group of closely related and largely allopatric or parapatric species. Affinities with the allies of the species group are discussed, and the morphological discrepancies differentiating the Japanese population are enumerated.

As one of the serial studies on the taxonomy of Conthocamptus mirabilis species group in South Korea, C. semicirculus Kikuchi, widely distributed in the southern part of the Far East, and C. coreensis n. sp. from the middle west of South Korea are recorded. Intraspecific variability of some important characters like outer caudal setae and the spinous process of male leg 3 exopod was examined in Korean population of C. semicirculus. Canthocamptus coreensis n. sp. possesses the plesiomorphic characters of the round and narrow hyaline membrane of anal operculum and lacking the sexual reverse transformation in female caudal rami, while it also evolves the apomorphic ones of the modified outer apical setae of male leg 4 exopod and the spinous process of male leg 3 exopod. A key to the five species of the species group known from Korea is prepared.
