Description of two new genera (Antarctotetilla, Levantiniella) and a new species of Tetillidae
Tetillidae is a sponge family distributed all over the world but with some genera apparently endemic from the Antarctic and Subantarctic (the “Antarctic clade”). Species identification results tricky due to the similarities of their morphological characters. However, molecular phylogenies have helpe...
