Holotype: AMW.53707, IN2017_ V03 _100; 9 June 2017; off Byron Bay , NSW, Australia, beam trawl, start: 28.05°S 154.08°E, 999 m, end: 28.10°S 154.08°E, 1013 m GoogleMaps . Paratypes: NMV F253033 About NMV , NMV F253035 About NMV , same locality as holotype.

Description. Holotype incomplete, represented bymajority of tube containing a fragment of tissue. Tube approximately 18 mm long, tapering anteriorly, and endingin aclosed point ( Fig. 28A View Figure 28 ). Tube material is easily torn. No males observed on tube. Tissue present within tube is possibly a single palp approximately 4 mm long and sinuous, surface appears smooth ( Fig. 28B View Figure 28 ). Specimen not observed alive.

Distribution. IN2017_V03, Station 100. Pilot whale carcass, off Byron Bay, New South Wales, Australia in 999–1013 m.

Etymology. This species is named after the town of Byron Bay, Australia, off which this whale fall was discovered.

Remarks. Osedax byronbayensis sp. nov. is known only from three incomplete specimens, therefore a complete morphological description was not possible. Molecular data demonstrates the three specimens to belong to the same species with high support ( Fig. 27 View Figure 27 ); uncorrected COI p -distances betweenthe three specimensare 0.4–0.6%. They arepositioned ina clade withother nude palp Osedax species and demonstrate a minimum uncorrected COI p-distance of 12.7% to other Osedax species (to Osedax ryderi Rouse, Goffredi, Johnson, & Vrijenhoek, 2018 ; TableS17). As with Osedax species Osedax crouchi Amon, Wiklund, Dahlgren, Copley, Smith, Jamieson, & Glover, 2014 , Osedax nordenskjoeldi Amon, Wiklund, Dahlgren, Copley, Smith, Jamieson, & Glover, 2014 , Osedax rogersi Amon, Wiklund, Dahlgren, Copley, Smith, Jamieson, & Glover, 2014 , and Osedax ventana Rouse, Goffredi, Johnson, & Vrijenhoek, 2018 , O. byronbayensis sp. nov. is described mainly on the basis of molecular data.
