Abstract:

To date, only three species of the sponge genus Tedania Gray, 1867 have been cited from the Iberian Peninsula: T. anhelans (Lieberkühn, 1859), T. toxicalis Laubenfels, 1930, and T. suctoria Schmidt, 1870, of which only one (T. anhelans) is considered a valid species for these coasts. This work is a study of all references to species belonging to this genus from these coasts and a detailed description of the morphology and anatomy of two new species: T. pilarriosae sp. nov. and T. urgorrii sp. nov., from the Ría de Ferrol (northwest Iberian Peninsula) characterized by their defined habitus and a spicular morphology. They differ from the other known Tedania, especially with regard to the ectosomal skeleton composed of stylotornotes.

Hasta la fecha, solamente se han citado tres especies del género Tedania Gray, 1867 en la Península Ibérica: T. anhelans (Lieberkühn, 1859), T. toxicalis Laubenfels, 1930, y T. suctoria Schmidt, 1870, de las cuales, solo una (T. anhelans) es considerada como válida en estas costas. En el presente trabajo se estudian todas las referencias bibliográficas correspondientes a las especies de este género en la zona y se describe detalladamente la morfología y anatomía de dos nuevas especies: T. pilarriosae sp. nov. y T. urgorrii sp. nov., procedentes de la Ría de Ferrol (NW de la Península Ibérica) que se caracterizan por poseer un habitus definido y una morfología espicular similar entre ellas, pero que difiere de las otras especies de Tedania conocidas, en especial en lo que se refiere al esqueleto ectosómico compuesto de stylotornotes.
