''Leucia violacea'' is a species of polychaete worm, commonly known as a "scale worm", in the family Polynoidae. This species occurs in the northeastern Atlantic Ocean.


Description

The body has 42 segments which are concealed by sixteen pairs of elytra in two rows. The length of this worm is about and the width . The prostomium has two lobes with a pair of acute anterior projections, a median antenna and a pair of lateral antennae inserted ventrally (beneath prostomium and median antenna), a pair of smooth palps and two pairs of eyes. The body is red to brown above and white beneath, and the scales are pink to violet. It can be distinguished from '' Leucia nivea '', the only other member of the genus, by the microtubercles on the scales being all conical while the macrotubercles are scattered and indistinct. Notochaetae distinctly thicker than neurochaetae. Unidentate and bidentate neurochaetae are present.Fiege, Dieter; Barnich, Ruth. (2009).
