In the framework of faunistic research conducted along the Apulian coast of Italy, three new species of thelepodid polychaetes are reported: Streblosoma pseudocomatus sp. nov., S. nogueirai sp. nov. and S. hutchingsae sp. nov. The taxonomic position of S. comatus is clarified and emended as Thelepus comatus. The described species are characterised by their C-shaped arrangement of uncini.
