A new species of sea anemone, Antennapeachia jambio sp. nov., was collected off Jogashima, central Japan. The presence of a single, strong siphonoglyph and physa-like aboral end, and the absence of the sphincter muscle classify this sea anemone within the family Haloclavidae. Two antenna tentacles and non-paired microcnemes categorize it into genus Antennapeachia, where only Antennapeachia setouchi Izumi and Yanagi, 2016 was included. However, unlike A. setouchi, A. jambio has two more marginal tentacles and two macrocnemes between ventral directives and ventro-lateral mesenteries. On the basis of details of these new characters of Antennapeachia, the diagnosis of the genus was revised to accommodate both species.
