Haplosyllis aurantiaca (Eisig, 1881)

Syllis aurantiaca Eisig, 1881: 270 –277.

Type material. Naples, Mediterranean Sea.

Remarks. Licher (1999) considered Syllis aurantiaca as a synonymy of Haplosyllis spongicola . The type material is probably lost, and the original description does not contain illustrations of chaetae and cirri, being impossible to confirm either the synonymy or the validity of the species.
