==Description==
''Hermadion magalhaensi'' is a short-bodied scale worm with fewer than 50 segments and 15 pairs of [elytra](/source/Elytron_(Annelida)). The elytra are large but leave a small median part of the body uncovered. The [prostomium](/source/prostomium) is bilobed and rounded anteriorly, lacking acute cephalic peaks. The antennal styles have slender papillae and the lateral antennae are inserted ventrally, beneath the median antenna. The [neuropodial](/source/Parapodium) lobe is elongate and tapering to a narrow tip. The [notochaetae](/source/Chaeta) have pointed tips and are distinctly thicker than the [neurochaetae](/source/Chaeta). The neurochaetae are simple and none have bidentate tips.<ref name ="barn"/><ref>Bock, Gordon, Fiege, Dieter & Barnich, Ruth 2010.
