Abstract
The occurrence of the subfamily Columbariinae in the eastern Indian Ocean is documented for the first time. Of the 5 species recognized, one, Coluzea distephanotis, new combination, has been previously described from the Torres Strait. Additional material suggests that this type locality is erroneous. Four new species, Coluzea aapta, C. icarus, C. liriope and C. gomphos are described. The eastern Indian Ocean species appear to be more closely related to their congeners from off southern and eastern Africa than to those from off New Zealand, suggesting post-Eocene vicariance of at least some elements of the psychrospheric faunas of the Indian and Pacific Oceans.
