Abstract
A. incubans sp. nov. is an internally brooding actinian known from the San Juan Archipelago, Washington, USA, and from Torch Bay, Alaska, USA. Found in sheltered intertidal habitats, this sea anemone average 25-30 mm in pedal disc diameter and has fewer than 65 tentacles. Females, hermaphrodites, sexually undifferentiated and possibly male individuals are known. A. incubans releases its brooded young through the pore at the tip of each tentacle; the young are tentaculate at the time of release. This species fits genus Bunodactis in all respects except that the outer tentacles of some individuals contain atrichous nematocysts. This feature alone, which is not apparent in all specimens of the species, possibly does not require naming a new genus. Rather, the definition of Aulactinia, a name that has priority over Bunodactis, is broadened to include this character.
