The postembryonic development of Trigoniulus corallinus (Gervais) was surveyed using the specimens collected from the Okinawa Island in November 25, 1990. The specimens in younger stages were obtained by culture of their eggs. The number of abdominal segments, legs, ocelli and ocellar rows, the length and the width of body, the live weight, the male gonopod and the secondary sex characteristics were surveyed. Based on these observations, we distinguished ten postembryonic stages (Ist-IXth larval stadia and Xth adult studium). The adult (Xth stadium) specimens had 47-51 abdominal segments and about 40 ocelli in nine rows. The adult male was about 37 mm in length, 3.5 mm in width, and about 350 mg in live weight, and the adult and subadult females were about 40 mm, 3.6 mm and about 450 mg, respectively.
