Redescriptions of <i>Sigambra grubii</i> Müller, 1858 and <i>Hermundura tricuspis</i> Müller, 1858 from Brazil and designation of neotypes (Polychaeta: Pilargidae)
Fritz Müller (1858) described polychaetes from Santa Catharina Island, Brazil. His type material was lost and his descriptions were brief. In an attempt to clarify the taxonomic status of his pilargids and to complete a revision of the pilargid genera of the world, some polychaetes collected at the type locality were analysed. On the basis of 16 specimens, Sigambra grubii is redescribed and the differences from S. bassi (Hartman, 1945) are clarified; S. grubbi is smaller and its median antenna is shorter than that of S. bassi. With one specimen of Hermundura tricuspis, the differences from other species are recognized, and Hermundura is regarded as a junior synonym of Parandalia Emerson & Fauchald, 1971. Neotypes are designated and deposited in the Smithsonian Institution. Keys to all species are also included for both genera.
