Paraflabellina gen. n. Figs 2, 34

Type species.

Flabellina ischitana Hirano & Thompson, 1990.

Etymology.

From Ancient Greek παρα (= beside, adjacent to) and Flabellina in reference to the external similarity of the type species F. ischitana to Flabellina s. str., but disparate molecular results that render the genus Flabellina s. l. paraphyletic in relation to the genus Calmella if F. ischitana is included within Flabellina .

Diagnosis.

Body narrow. Notal ridge completely absent. Cerata on high compound stalks. Rhinophores with ring lamellae, shorter than oral tentacles. Anterior foot corners present. Anus pleuroproctic. Rachidian teeth with narrow compressed cusp and distinct denticles. Lateral teeth denticulated with attenuated process basally. Proximal and distal receptaculum seminis. Long vas deferens without distinct prostate. Penis conical.
