  • The cumacean fauna currently contains more than 1200 species worldwide (Wafting, 1997). Many of the habitats where cumaceans are likely to be found, such as estuaries, shallow embayments, beaches, tidal flats, and the inner continental shelf, have not yet had their cumacean fauna documented (Watling, 1997).

  • A taxonomic study was carried out on the cumacean specimens collected from shallow coast of the Yellow Sea in Korea. As a result, Bodotria ovalis Gamo, 1965 is redescribed as new to Korean cumacean fauna based on the differences between ours and previous researchers' views on this species. B. ovalis rarely occurs in the coast of the Yellow Sea.

  • Thirteen cumacean species in four families were identified from the southern coast and Chejudo Island in Korea. Three of them, Campylaspis pumila Gamo, Cumella alveata Gamo, and Cumella glaberata Gamo, are recorded newly to Korean fauna. Among them, female of C. alveata is described for the first time in the would.

  • Two Campylaspis species, C. amblyoda $Gam\hat{o}$, 1960 and C. reticulata $Gam\hat{o}$, 1960, are redescribed as new to Korean cumacean fauna. Campylaspis amblyoda is characterized by having a carapace with five or six pairs of pellucid spots on dorsal surface, a pair of projections near proximal portion of frontal lobe, and lacking sulcus on lateral portion. Campylaspis reticulata is easily distinguished from its congeners by having a pair of broad sulcus and several large reticulations on lateral portion of carapace. The collected Korean specimens were congruent with the original descriptions, except for several minor differences. Herein, we add two Campylaspis species to the Korean cumacean fauna. The female of C. reticulata is described for the first time. A key to the Korean Campylaspis species is also provided.

  • Subtidal zonation of a cumacean Bodotria biplicata was investigated in the sandy shore surf zone of Dolsando, southern Korea. Three replicate samples were taken with a sledge net at three sites, such as the surface and bottom of 1 m depth and waters edge, at hourly intervals over the neap and spring tide cycles on January 1993 (n=225). B. biplicata, the most dominant cumacean in this area, exhibited peak density at the bottom while about $0.6\%$ of total catch was collected at the surface. Mean density during the neap tide cycle was slightly higher than that during the spring tide cycle. The depth of subtidal zone influenced the total catch of B. biplicata. The changes in density were related to the depth of subtidal zone rather than day-night cycle or ebb-flood tide. The results obtained in this study suggest that the diel vertical migration is not distinct. During both neap and spring tide cycles, B. biplicata attained a density maximum at the same level of about 90 cm below lower low water (LLW). It is likely, therefore, that this species performs shore- and seaward horizontal migration fortnightly. The speed and distance of migration may be directly related to the beach slope and tide range. Ontogenetic differences in subtidal distribution were observed. Juveniles and manca larvae tended to occur lower areas than the adults. Such differences may reduce intraspecific competition for diets.

  • Through taxonomic survey of specimens collected from the coasts of Korea from 1993 to 2006, Dimorphostylis echinata $Gam{\hat{o}}$, 1962 is new to Korean cumacean fauna. Especially, the adult male and female of D. echinata are described for the first time. Dimorphostylis sculpturensis Vassilenko and Tzareva, 1990 is proposed as a synonym of D. acroplicata Harada, 1960 in this research. Also, its female is redescribed for the first time in Korea.

  • Two diastylid species, Dimorphostylis manazuruensis Gamo(1960) and Dimorphostylis longicauda Gamo(1962), are recorded as new to Korea cumacean fauna. The subadult male of D. longicauda is described for the first time. As a result, the genus Dimorphostylis found in Korean waters now consists of eight species.

  • The genus Nippoleucon was newly established within the family Leuconidae and two Hemileucon species, N. hinumensis (Gamo, 1967) and N. enoshimensis (Gamo, 1967), were transferred to this genus. Through examination of the cumacean specimens from the Gwangyang Bay of the Korea Strait, N. hinumensis is recorded as new to Korean fauna. The genus Nippoleucon is reported from Korea for the first time.

  • This study on Korean cumaceans was based on the specimens collected from K jedo I. and Chejudo I. in Korea. Two species in the Genus Bodotria (Bodotriidae) were identified: B. biplicata Gam , 1964 and B. carinata Gam , 1964. They are redescribed and illustrated as new records to Korean fauna. Especially, male of B. carinata is described at first on the basis of the specimen from Korean waters. As a result, Korean cumacean fauna consists of 10 species of five genera in three families.

  • This study dealt with cumacean specimens collected from the shallow waters of the South Sea and East Sea, Korea. Campylaspis fusiformis Gam$\hat{o}$, 1960 belonging to the family Nannastacidae is newly recorded to Korean fauna. This species resembles C. pumila and C. striata in having a similar body form and a pair of narrow lateral sulcuses on the carapace, but it is easily distinguished from them by the dactylus of the pereopod 2 which is more than 3.5 times the length of the propodus and bears many setae (about 20) on the surface. This species mainly occurs in the Korean and Japanese waters.
