AbstractTwo new species of the genus Bathyacmaea Okutani, Tsuchida and Fujikura, 1992 are described and illustrated from deep-sea chemosynthetic areas in the western Pacific. Bathyacmaea austrina new species, sampled from hydrothermal vents in Okinawa Trough at depths of 1314-1374 m, is closely related to Bathyacmaea secunda Okutani, Fujikura, and Sasaki, 1993 in having a rounded shell outline, but differs in having beaded shell sculpture. Bathyacmaea brevidentata new species, collected from a methane seep area in the South China Sea, is most similar to Bathyacmaea lactea Zhang, Zhang, and Zhang, 2016 in having a thick shell with regularly-spaced concentric growth lines, but can be separated from it by having a highly arched shell with a concave aperture margin. Phylogenetic reconstruction based on partial sequences of COI also support their placements within Bathyacmaea.
