Title

A new species of Sphinctrella (Demospongiae: Astrophorida) and remarks on the status of the genus in the Mediterranean

Abstract

We describe in this study a new Mediterranean species of the genus Sphinctrella Schmidt. Sphinctrella 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. aberrans, three other species of Sphinctrella are known from the Mediterranean according to the literature: Sphinctrella gracilis Sollas, Sphinctrella horrida Schmidt and Sphinctrella verrucolosa Pulitzer-Finali. However, the re-examination 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.
