| Abstract |
Calliostoma bellatrix n. sp. is described from depths of 250 to 400 metres depth in the seaway between northern Australia and the southern Indonesian archipelago, and extending into the eastern Indian Ocean. Its smooth shell, with flat sides to the whorls and an acutely angled periphery ornamented with a "double" nodulose keel, render it unique among Indo-Pacific calliostomes, and it may be the sister species to C. schroederi Clench and Aguayo from similar depths in the Caribbean Sea. Both C. bellatrix and C. schroederi clearly belong within the subgenus Ampullotrochus Monterosato. |
