Range — the genus is known only from the Eocene to the upper Oligocene of New Zealand.

This genus shows relationship with the European-North American lower Tertiary Eopleurotoma. Both have the sinus spreading from the peripheral carina on to the shoulder. The respective protoconchs, however, differ considerably; that of Eopleurotoma is small, smooth and paucispiral, that of Eoturris is narrow, elongate-conic, with axials over the last quarter whorl.
