Abstract

Based on 16 specimens from the Southwestern Atlantic coast (Argentina and Brazil) we reinterpret the taxonomic position of Tessera gemmaria Goy, 1979, a stauromedusa considered as incertae sedis for a long time. Using external morphology, histologicalpreparations and molecular data (16S and COI) we conclude that T. gemmaria is an early stage of a cerinula, the long-lived planktonic larval stage of the Ceriantharia (Anthozoa).
