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.

Four species of the family Diastylidae (Crustacea: Cumacea) are redescribed based on the samples collected in the Yellow Sea. They are Leptostylis hexaspinula (Liu and Liu, 1990), Dimorphostylis brevicaudata (Zimmer, 1903), Dimorphostylis asiatica Zimmer, 1920 and Dimorphostylis hirsuta Gamo, 1960. Except Dimorphostylis asiatica the three species are new to the Korean fauna.

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.

In this study, a new species, $Dimorphostylis$ $breviplicata$ n. sp. is described and illustrated on the basis of specimens collected from the shallow Korean waters. This new species is similar to $Dimorphostylis$ $brevicaudata$ (Zimmer, 1903), $Dimorphostylis$ $acroplicata$ Harada, 1960 and $Dimorphostylis$ $valida$ Gam$\hat{o}$, 1962 in that the carapace has three pairs of oblique ridges on the surface. However, the new species is distinguished by the combination of the following features: the middle oblique ridge is short and not joined to the other oblique ridges; the transverse ridge is absent on the frontal lobe; the dorso-median process on the pereonite 5 is only barely visible; the male telson has no short stout seta on the both lateral margins; the length ratio of the first to remaining articles combined on the male uropod is 1 : 0.7. A key to the Korean $Dimorphostylis$ species is provided. Also, $Diastylis$ $alaskensis$ Calman, 1912 is redescribed as a new recorded species of the Korean fauna.

A new species, Dimorphostylis namhaedoensis (Cumacea, Diastylidae) is described on the basis of the specimens collected from southern shallow coast of Korean peninsula. The new species resembles four other species, D. asiatica, D. valida, D. hisuta and D. acroplicata, in having three apical spines on the terminal margin of the male telson and three pairs of the oblique ridges on the carapace, but are obviously distinguished from them in that the pattern of the ridges on the carapace is different and the third article of the antennular peduncle is very long in female. Furthermore, the dorsal carina of the female carapace has a row of forward spines and among the three apical spines of male telson, the median spine is much smaller than the lateral ones.
