The first zoeas of Eualus leptognathus are described and illustrated in detail from laboratory-hatched material. Morphological comparison is made with previous description of this species from Japan. Minute rostrum and two anteroventral denticles behind pterygostomian spine on the carapace readily distinguish the first zoeas of Eualus leptognathus from those of Eualus sinensis, the only known zoeas of Eualus from Korean waters.

First zoeas of Alpheus albatrossae (Banner, 1953) are described and illustrated for the first time, based on laboratory-hatched zoeas from a female collected in Ulleung-do Island, eastern Korea. The first zoeas of A. albatrossae can be distinguished from those of seven known species of Alpheus (A. brevicristatus, A. digitalis, A. heeia, A. japonicus, A. lobidens, A. richardsoni, and A. sudara) from Korea by having 6-segmented scale of the antenna and the endopod of the first maxilliped with four terminal setae.

The first zoeas of Nursia rhomboidalis and Pyrhila carinata were obtained from laboratory condition. They are described and illustrated for the first time. Morphological comparison with those of other Korean described species of the family Leucosiidae reveals that the zoea of N. rhomboidalis is very similar to those of Myra fugax and Arcania undecimspinosa based on characteristics of the carapace spines length, the antenna morphology, the maxilla endopod setation, and the telson, whereas, the zoea of Py. carinata coincides well with those of Philyra kanekoi and Pyrhila pisum based on characteristics of the carapace spines length, the antenna morphology, the maxilla endopod setation, and the telson. Furthermore, we find that at least two groups of zoeas exist in the Korean species of the subfamily Ebaliinae. A provisional key to the known zoeas of ten leucosiid species from Korean waters is provided.

One ovigerous crab of Hemigrapsus longitarsis (Miers, 1879) was collected in Jeju Island, Korea and their larvae were reared in the laboratory. Five zoeal and one megalopal stages are described and illustrated in detail. Morphology of the zoeas slightly differs from that in the previous record. Within the genus Hemigrapsus, H. longitarsis shows similarity closer to H. sanguineus and H. penicillatus than to H. sinensis based on the zoeal morphology. The zoeas of H. longitarsis can be distinguished from those of the two other species in having a dorsal carapace spine with minute spinules which is naked in H. sanguineus and H. penicillatus. A provisional key is provided to aid the identification of the grapsid zoeas in Korea.

The first zoeas of Chinese ditch prawn Palaemon gravieri (Yu, 1930) and carpenter shrimp Palaemon serrifer (Stimpson, 1860) are described and illustrated in detail based on laboratory-hatched material. They are distinguished from those of Palaemon ortmanni (Rathbun, 1902) and Palaemon pacificus (Stimpson, 1860), previously known larvae from Korean waters by the length of the rostrum and endopod of antenna, the shape of the third abdominal somite, and ornamentation of the fifth abdominal somite. Larval characters of the genus Palaemon are revised. A. provisional key to the known first zoeas of Palaemon from Korean waters is given.

The first zoeas of Parapanope euagora and Halimede fragifer hatched in the laboratory from two ovigerous galenid crabs of Pilumnoidea were collected from Jindo Island, Jeolanam-do, southern Korea. Their morphologies are described in P. euagora for the first time in the world and re-described in H. fragifer with the color images of live zoeas. In this study, they show a general morphology of Pilumnoidea by having a long antennal exopod, an endopod of the maxillule with 1, 2+4 setae, an endopod of the maxilla with 3+5 setae, and a fork of the telson with two lateral armatures. However, the first zoea of P. euagora differs from other known zoeas of pilumnoid species including H. fragifer by having a long antennal exopod with a medial seta and spine, not two spines, and a fork of telson with two lateral setae, not a seta and spine. Such characteristics of the antennal exopod and the fork of telson are reported for the first time in the pilumnoid zoeas. A comparison between the first zoeal stage of H. fragifer in this study and that of Terada shows minute differences in the characteristics of the antennule and the fork of telson.

The zoea1 stages of Philyra kanekoi Sakai, 1934 were obtained by laboratory rearing. Three zoeal stages were described and illustrated in detail. Zoeal morphology was compared with those of other described species of the family Leucosiidae. Morphological comparisons with congeneric species revealed that zoeas of P. kanekoi were more similar to those of P. pisum and P. platychira than to other Philyra. The present material could be distinguished from other Philyrinae species by having no dorsal carapace spine, a spinous tip of the antenna, and no chromatophore on the base of a dorsal carapace spine. Within the family Leucosiidae, the zoeas of three Philyra (P. kanekoi, P. pisum and P. platychira) showed the greatest affinities with Leucosia sima and L. pubescens (Leucosiinae), and the number of setae on the basipod of the first maxilliped could be very useful characterisitcs for indentification between Philyra and Leucosia zoeas.

The complete larval development of Chiromantes haematocheir was obtained by laboratory rearing. Five zoeal and one megalopal stages are described and illustrated in detail. Morphological characteristics of the larvae slightly differ from those of Lee (1988), especially in the setal presence of mouthpart appendages. Seven sesarminid zoeas (Parasesarma acis, Parasesarma pictum, Perisesarma bidens, Sesarmops intermedius, Chiromantes dehaani, Chiromantes haematocheir, and Nanosesarma gordoni) can be distinguished from each other in characters of the carapace spines, the antennal exopod and the fork of telson. A provisional key is first provided to aid the identification of seven sesarminid zoeas in Korea.

The first zoea of Camptandrium sexdentatum is described for the first time with a digital image of live zoeas. An ovigerous crab of C. sexdentatum was collected at the muddy sand flat in Namhaedo Island on 2 June 2012 and hatched in the laboratory on 6 June 2012. In Camptandriidae, the first zoea of C. sexdentatum is distinguished from the first zoeas of Cleistostoma dilatatum and Deiratonotus cristatum by having no dorsal and lateral carapace spines, an abdomen significantly broadened posteriorly, and a subovoid telson without forks. Especially, the finding of a subovoid telson without forks is the first report in brachyuran zoeas.
