The recently erected macrocnemic family Hydrozoanthidae comprises relatively few species
recorded from tropical and subtropical regions. In the Atlantic Ocean, this family has been
reported only from three locations: the Caribbean Sea, the Argentine continental shelf and
the Cape Verde Islands. Based on a study of colonies collected during scuba diving at
Alcatrazes Archipelago’s main island (São Paulo State), south-eastern Brazil, a new species
belonging to the genus Terrazoanthus is described as T. silveirai sp. nov. Vaga, Migotto &
Kitahara. Morphological and ecological observations coupled with molecular analyses
revealed a unique cnidome, a novel facultative association with sponges, and confirmed the
phylogenetic position of this new species within Hydrozoanthidae. Our results represent the
second record of Hydrozoanthidae and Terrazoanthus from the South-western Atlantic,
expanding the sparse taxonomic knowledge of the order Zoantharia in this area.
