Description

In the original description, Powell described the genus as below:

The new genus Exomulopsis is characterised by its strong superficial resemblance to the Turrid genus Exomilus , i.e. attenuate spire, sagged, low keeled whorls, crossed by axial folds, and a narrow rectangular aperture, but without an anal sinus. The genus Retizafra , to which spica and its allies have most in common, has a fewer whorled more broadly conic protoconch and the shell is of more conventional fusiform shape, the sculpture being axial reticulated by spiral cords. [2]

Taxonomy

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 . [2] Boyer et al. (2022) suspect that the genus is likely a synonym of Gatliffena . [3]

Distribution

Exomilopsis is found in the temperate waters of south of Australia and around New Zealand. [2]
