Exomilopsis is a genus of minute gastropod molluscs belonging to the family Columbellidae. Both species are found in Oceania.
In the original description, Powell described the genus as below:
The genus' tall, conical protoconchs are more similar to barrow forms of columbellids.
The genus was first described by A. W. B. Powell in 1964, who named Mangelia spica as the type species, and also described a new species in the genus, E. hipkinsi. Boyer et al. (2022) suspect that the genus is likely a synonym of Gatliffena.
Exomilopsis is found in the temperate waters of south of Australia and around New Zealand, and is found in Miocene fossils in Victoria, Australia.
Species within the genus Exomilopsis include:
