A new hydromedusa Eirene lacteoides (Leptomedusae; Eirenidae) from Toba, Mie Prefecture, Japan is described based on the laboratory-reared 18 male medusae and 33 immature ones. The new species resembles Eirene lactea (Mayer, 1900) in having distal projections of peduncle, but can be distinguished by the presence of an adaxial papilla on every well-developed tentacular bulb and even on some small tentacular bulbs bearing very short tentacles. The development of medusa, the nematocyst equipment, and the distributional records of E. lacteoides are also described.
