Polychaetes of Greece: an updated and annotated checklist Faulwetter, Sarah Simboura, Nomiki Katsiaras, Nikolaos Chatzigeorgiou, Giorgos Arvanitidis, Christos Biodiversity Data Journal 2017 5 20997 20997 Gravier, 1900 Gravier 1900 B ranchiosyllis exilis 0 20997 species B ranchiosyllis exilis  Notes Species complex. The complex of pseudo-cryptic species around Branchiosyllis exilisis confused and in need of revision and it is likely that specimens around the world recorded under the name Branchiosyllis exilisbelong to different species ( San Martinet al. 2008). Specimens from the Mediterranean recorded as Branchiosyllis exiliscould also belong to the native Mediterranean species Branchiosyllis cirropunctata(Michel, 1909), as the two species differ mainly in the shape of the shaft head of the falcigers and Branchiosyllis cirropunctatawas considered a synonym of Branchiosyllis exilisuntil recently.
