Abstract
In this paper we describe three new species of Tetilla from stretches of the coast of Bahia, northeastern Brazil, all collected in shallow waters and soft bottoms. Tetilla pentatriaena sp. nov. is distinct from other species of the genus by the uniquepossession of five categories of triaenes: two of protriaenes and three of anatriaenes. Tetilla muricyi sp. nov. and Tetilla rodriguesi sp. nov. are the first species in the genus registered exclusively from mangrove ecosystems and are distinct from most species of Tetilla by their lack of microscleres. Tetilla muricyi sp. nov. differs from all species by its spiculation and by having a reticulate skeleton of secondary oxeas. Tetilla rodriguesi sp. nov. differs from other species without sig-maspires by the presence of three categories of oxeas, two of trichoidal protriaenes and one of exclusively rhizoidal anatriaenes. In addition to the three new species described here we also provided one identification key to the Tetilla species occurring in the Atlantic Ocean.
