Voucher. Sea Lion: station 7MFA (specimen), TOROA: station T1FA (tube).
Diagnosis. Voucher complete specimen, partially exposed from muddy tube; 38mm long and 1.8mm wide; with a single pair of emergent postbranchial hooks present, tips sharply bent at 45 degree angle.
Prostomium without eye spots. Eighteen thoracic chaetigers; dorsum of chaetiger 4 with a narrow membranous fold with serrated free margin, with few (about 5) equal-sized, sharp, triangular serrations. Two dorsal, basally fused groups of four distally tapered, cylindrical branchiae.
Tube: loosely packed (easily broken) fine mud, very sparsely encrusted with larger particles and or/shell fragments.
Remarks. Falkland Island specimens found in this study agree well with Melinna arnaudi Parapar and San Martín (1997) from Livingston Island 104-443m depth. We refer readers to the comprehensive description as provided by the original authors. Other Melinna species were also found in this study, see page for Melinna sp. 1.
