A revision of the Fabriciin genus Augeneriella Banse, 1957 (Polychaeta: Sabellidae)

The Sabellidae polychaete genus Augeneriella Banse is revised based on a reexamination of the type material of most species. Augeneriella hummelincki hummelincki Banse is shown to have vascularized, ventral filamentous appendages which can display up to four branches in a pectinate arrangement, as opposed to only a single dichotomy as originally described. The status of A. hummelincki indica Banse is discussed. The species A. bansei Hartmann-Schröder is based on a single, probably aberrant, specimen in which ventral filamentous appendages are unbranched. Additional material will likely show that this species displays the typical branched condition for ventral filaments. Augeneriella dubia Hartmann-Schröder can be ascribed to an undescribed genus which has been found in Atlantic, Indian, and Pacific Oceans. Two new species of Augeneriella from the Aldabra Atoll, Indian Ocean, are described.
