Filogenia e taxonomia de phlebobranchia (tunicata: ascidiacea)

Abstract

Phlebobranchia, one of the three orders of Ascidiacea, is characterized by its simple oral tentacles, pharynx not folded, and gonads associated with the digestory tube. Despite being the less speciose order, species of Phlebobranchia can be found all around the world, from shallow water to the deep-sea, and it has the largest morphological ected and redescribed. Five new species were detected (one of Ascidiidae, published in the last year, and four of Perophoridae, manuscript in progress), and there are five morphotypes unidentified.
