  • 실험실에서 사육된 애기털보부채게의 유생은 4 zoea 유생기를 가졌고, zoea 유생기를 완료하는데 25$^{\circ}C$ 수온에서 최저 15일이 걸렸다. 각 zoea 유생기의 형태적 특징을 상세히 기록, 도시하고 Pilumnidae과의 이미 보고된 다른종의 제 1 zoea유생과 그 특징을 비교하였다. 애기털보부채게는 구부부속지나 갑각극의 형태적 특징에서 Pilumnus 속의 다른 종들과 차이가 없었으나 복부측돌기는 복부 제 2, 3, 4, 5절에 존재하므로 Pilumnus 속의 다른 종들과 형태적 차이를 보이고, 이 특징은 세가지 부채게에서 볼수 있는 복부의 형태적 특징으로 두종간에 어떤 유연관계가 있는 것 같다.

  • We obtained four zoeal stages of Harrovia japonica from laboratory-hatched material. They are described, illustrated in detail, and compared with those of other known species in the family Pilumnidae. The general zoeal morphology of H. japonica coincides well with those of other known species of the Eumedoninae (excluding Echinoecus pentagonus) and Pilumnus minutus of the Pilumninae. In order to facilitate the study of planktoncollected material, we provide a key for the identification of seven known zoeae of the Eumedoninae from the IndoPacific.

  • Ovigerous crab of Echinoecus nipponicus of subfamily Eumedoninae in Pilumnidae was collected from Seogwipo, Jejudo and hatched in the laboratory. The first zoeal stage of E. nipponicus is reported for the first time in the world and its digital image of live zoeas is provided. The first zoea of E. nipponicus has yellowish red chromatophores which occurring behind eyes, on dorsal spine and on anterior margin of telson, reddish brown chromatophores on abdominal somites 2-5 ventrally, dorsal, rostral, and lateral spines shorter than carapace length, three aesthetascs and two setae on the antennule, two medial setae on the antennal exopod, lateral processes on the abdominal somites 2, 3, and two lateral spine and one dorsomedial spine on the telson.

  • Two pilumnid species, Echinoecus nipponicus and Zehntneriana amakusae, are described and illustrated from Jejudo Island, southern Korea. These species are recorded for the first time in Korea, and Z. amakusae is the sole representative of the subfamily Rhizopinae of the family Pilumnidae.
