  • The 7 zoeal and 1 megalopal stages of Cha~bdi8 bimaculata (Miers, 1886) are descrihed and iflustrated in detail from larvae reared in lahoratory. Under isboratory conditions of 22$^{\circ}C$ temperature and 33.3~ salinity, the magalopa was attained in 32 days or more after hatching. The larval morphology of the first zoea of C. bimaculata are coincide with those of Charybdis species by hearing lateral spines on carapace, ~type antenna, A-type telson, 1,6 setae on the endoped of maxillule, and 6 setae on the endopod of maxilla. Morphological features of C. bimaculata larvae were compared to the previous descriptions of larvae of the other spedes helonging to the same genus.

  • The complete larval development of Scopimera bitympana Shen was descdbed and mustrated from the larvae reared in the lahoratory. S bItympana had five, or occasionally six, zoeal and one megalopal stages. At $25^{\circ}C$, the megalopa and the first crab instar were attained in 24 and 38 days (31 and 48 days in six zoeal series) after hatching respectively. S.bitympana zoeae can be distinguished from other described zoeae in the genus by the toothed carapace spines and the telson with a dorsal and two ventral spines. Megalopa of this species can be distinguished from other ScopimeTa spedes by the feature of carapace. Other minor morphological features of S. bitympana larvae are compared to the previous descripdons of larvae of the genus and the morphological differences are briefly discussed.

  • The complete larval development of Hemigrapsus penicillatus(De Haan, 1835) from hatching to first crab stage was obtained by culture in the laboratory. Under culture conditions with salinity 33.3% , temperature $25^{\circ}C$, and photophase 14/10 h light/dark, the megalopa and the first crab instar were attained in minimum of 18 and 29 days after hatching respectively. Five zoeal stages and a megalopal stage are described and illustrated in detail. Morphological characters of H. penicillatus larvae were compared with those of other members within the subfamily Varuninae. Morphological differences among H. penicillatus, H. sanguineus and H. sinensis in megalopal stage are tabulated.

  • As a result of continuous taxonomic study on crabs, Clistocoeloma villosum (A. Milne-Edwards, 1869) is newly reported from Korean waters. C. villosum has no epibranchial tooth on the carapace, while C. merguiense De Man, 1888, only recorded species of this genus in Korean fauna, has two epibranchial teeth. The description and illustrations of C. villosum are provided herein. Korean Sesarmid crabs now consist of 10 species belonging to six genera.
