Benthofascis lozoueti is a species of sea snail, a marine gastropod mollusk in the family Conorbidae.

[1] These snails are predatory and venomous.

They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.

The length of an adult shell attains 21.5 mm, its diameter 9.1 mm.

This marine species is endemic to the Norfolk Ridge and found at a depth of 530 m; also off New Caledonia.
