  • Three xanthid crabs from Chejudo island, viz., Forestia depressa (White, 1847), Pilodius nigrocrinitus Stimpson, 1858, and Palapedia integra (De Haan, 1835) are recorded as new to the Korean fauna. Up to data the Korean crabs of the family Xanthidae s. restr, consist of 15 species of 8 subfamilies.

  • The first zoea of Microcassiope orientalis is described and illustrated from laboratory hatched materials. Comparisons with previous studies of the first zoeal stages in the Xanthidae from Korean waters, revealed that some former studies were incorrected. The first zoea of M. orientalis described by Ko was identical to the first zoea of Macromedaeus distinguendus described by Terada. In addition, zoeal stages of Nanocassiope granullipes described by Ko & Clark was revealed the zoeal stages of M. cassiopes. So, the first zoea of M. orientalis is redescribed and illustrated in detailed with color photo herein, and compare its morphological characteristics with previous described zoea of N. granulipes by Ko & Clark.

  • Three xanthid crabs, Liomera margaritata, Neoxanthops lineatus and Pilodius miersi, are described and illustrated for the first time in Korea. Liomera margaritata and N. lineatus are the first species of their genera to be found in Korea. The three species represent extensions of their previously known ranges and bring the number of known species of the xanthid crabs to 25 from Korean waters.

  • The first zoea of Liomera bella belonging to the subfamily Liomerinae is described and illustrated for the first time. Its morphological characteristics are compared with those of other known species of the Xanthidae The general morphology of it corresponds well with zoeas of the Xanthidae. Based on the zoeal morphology, the zoea of L. bella shows a greatest affinity with those of Xontho incisus and Pseudomedaeus agassizii by having the exopod of antenna with two setae, the terminal segment of the endopod of the second maxilliped with six setae, and the fork of telson with one stout and one smaller lateral spines.

  • Gaillardiellus orientalis (Odhner, 1925) has been reared in the laboratory, form hatching to the first young crab stage at $25^{\circ}C$. The four zoeal stages and one megalopal stage are described and illustrated in detail. Within the subfamily Actaeinae, the zoea of G. orientalis differs from the other known zoeae in the characteristics of the antenna and the telson.

  • The larval development of Parupilumnus trispinosus Sakai, 1965 completed in the laboratory consisted of four zoeal stages and one megalopal stage. Completion of the lanral development required at least 18 days at 20-25"C. The morphology of the lanrae of each stage is described in detail, and comparisons are made with larvae of other 11 species of the subfamily Pilumninae. Although, the zoeae of the subfamily Pilumninae show almost consistent characteristics of the mouthpart appendages, in the characteristics of the carapace spines and the abdominal lateral knobs they can be divided into five groups: (1) the genera Heteropanope and Heteropilumnus, (2) the genera Actumnus and Pilumnus, (3) Pilumnopeus makiona and P sewutifrons, (4) Porupilumnus trispinosus, and (5) Pilumnopeus eucratoides and. p indic${\alpha}$.

  • Novactaea pulchella was reared in the laboratory, from hatching to the megalopal stage at $25^{\circ}C$. The larval stage of it consists of two zoeal and one megalopal stages. The first zoea of the present study differs from that described by Terada (1990) in the setal presence of the carapace, the maxilla and the maxilliped, and the lateral process on the abdominal somite. It is reported for the first time that brachyuran zoeas belonging to a species share two types of lateral processes on the abdominal somites. They are either on the abdominal somites 2 and 3 or on abdominal somites 2 to 5. A provisional key is provided to aid the identification of the actaeine zoeas in Korea and the adjacent waters.
