Abstract
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.
