Etymology The name of the genus is formed by the Latin prefix nudus, meaning 'naked' or 'bare', and the name of the type genus of the family, Syllis Savigny in Lamarck, 1818, making reference to the absence of antennae, tentacular cirri, and dorsal cirri in the type material of the species.  [details]

Diagnosis Original diagnosis by Knox & Cameron (1970: 77): "Body short, up to 35 segments; first segment partially fused to the prostomium and lacking parapodia. Prostomium with two pairs of eyes and lacking antennae. Palpi paired, large, bulbous, united at the base and directed ventrally. Pharynx with a single large terminal tooth and smooth ring. Dorsal cirri absent; ventral cirri cirriform; parapodia with one kind of setae, compound unidentate falcigers.[details]

Diagnosis New diagnosis by San Martín et al. (2009: 1470): "Body small, fragile, of meiofaunal size. Segments not fused. Prostomium proportionally large, with four eyes and sometimes a pair of anterior eyespots; three antennae, and two palps. Palps separate, free from each other, but close at their bases, triangular to distally rounded in shape. Median antenna inserted on middle of prostomium or on line with lateral antennae. Nuchal organs as two ciliated grooves; cilia extending to laterals of prostomium. Two pairs of tentacular cirri. Dorsal cirri on all chaetigers, long, cylindrical, smooth or slightly rugose. Subcirral papilla absent. Ventral cirri not modified. Compound chaetae with both unidentate and bidentate blades on same parapodium, or all indistinctly bidentate, with unidentate appearance; bidentate blades having proximal tooth very small, similar to a spine; spines on margin short. Tips of aciculae tricuspidate or lancetshaped. Pharynx small, shorter than proventricle; pharyngeal tooth located near anterior rim, elongated to ovate. Reproduction by epigamy, probably with dorsal incubation of eggs, verified on two species; care of juveniles on dorsal cirri, verified in one species.[details]

Etymology The name of the genus is formed by the Latin prefix nudus, meaning 'naked' or 'bare', and the name of the type genus of the family, Syllis Savigny in Lamarck, 1818, making reference to the absence of antennae, tentacular cirri, and dorsal cirri in the type material of the species.  [details]
