Note

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 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.
