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. Florida Atlantic University.
