Abstract: In December 2006, we found hydroids of bivalve-inhabiting hydrozoans on the southern coasts of China, associating with Crassostrea sp, and their mature medusae were obtained by culture in the laboratory. The morphology of both hydroids and medusae of Eugymnanthea japomca Kubota from Zhang pu is described with photographs as the first information enabling the connection of the two developmental stages based on the Chinese materials. The identification as Hebella dissymetrica Billard of specimens formerly collected from Tong an Bay in 2001 in the same area is corrected here as the present species after checking many specimens deposited in Xiamen University, China.
2006年12月初旬に中国南部沿岸の樟浦(Zhang pu)から採取されたマガキ属のl種Crassostrea sp.から初めてカイヤドリヒドラ類のポリプを発見し,実験室での飼育により成熟クラゲを得た.その結果,カイヤドリヒドラクラゲEugymnanthea iaponica Kubotaと同定できたので中国産の本種のポリプとクラゲの形態をセットで記載する・以前,同海域の同安湾(Tong an Bay)よりマガリコップガヤHebelladissymetrica Billardなるクラゲがプランクトンサンプルから発見され記載されていたが,その標本精査の結果,本種と判明した.
