Abstract[EN]We describe in this study a new Mediterranean species of the genus Sphil1ctrella SCHMIDT. Sphil1ctrella aberrans sp. nov. is characterized by the presence of malformed ortho.:.plagiotriaenes and pseudocalthrops, a category of spirasters with a very thick central axis, microxeas with attenuate ringed ornamentation, and a very fine, pore-like fenestration of the ectosome of the exhalant sieves. Apart from S. aberral1s, three other species of Sphil1ctrella are known from the Mediterranean according to the literature : Sphillctrella gracilis SaLLAs, Sphinctrella horrida SCHMIDT and Sphinctrella verruca/asa PULITZER-FINAL!. However, the reexamination of the single Mediterranean individual claimed to be S. horrida made evident that this specimen was misidentified and the species actually does not exist in the Mediterranean.
[ES]En este estudio se describe una nueva especie mediteminea del genero Sphinctrella. Esta especie, Sphinctrella aberrans sp. nov. , se caracteriza par la presencia de orto-plagiotrienas y pseudocaltropas can malformaciones, par poseer una categaria de espinisteres can el eje central muy grueso, par una ornamentacion anillada muy debil en las microxas y una fenestracion puntiforme del ectosoma de las cribas exhalantes. Segun la bibliografla, otras tres especies del genera Sphinctrella, ademas de S. aberrans, estan presentes en el Mediterraneo : Sphinctrella gracilis SOLLAS, Sphinctrella horrida SCHMIDT y Sphinctrella verruc%sa PULITZER-FINAL!. Sin embargo, la revision del unico material hasta ahora atribuido a la especie S. horrida en el Mediterraneo ha revelado que el ejemplar fue mal identiftcado y que dicha especie no existe realmente en el Mediterraneo.
