Abstract

The syllid genus Anguillosyllis is relatively rare and mainly restricted to deep waters. The phylogenetic position of the genus was only recently inferred, while its reproductive mode, an important trait in the classification of the Syllidae, remains unknown. We describe herein our finding of one specimen of Anguillosyllis lanai with fragile egg capsules dorsally attached to some parapodial lobes, the first observation to date providing information about reproductive aspects of animals of the genus, and discuss possible evolutionary and phylogenetic implications of this finding.
