Calmella Eliot, 1910 Figs 33, 34

Type species.

Eolidia cavolini Vérany, 1846.

Diagnosis.

Body narrow. Notal edge completely absent. Cerata on short stalks in several groups. Rhinophores smooth, larger than oral tentacles or similar in size. Anterior foot corners present. Anus mixed: pleuroproctic shifted towards dorsal acleioproctic position. Distinct oral glands. Rachidian teeth with narrow compressed cusp and distinct denticles. Lateral teeth weakly denticulated to smooth with attenuated process basally. Single distal receptaculum seminis. Moderately long prostatic non-granulated vas deferens. Penis conical.

Species included.

Calmella cavolini ( Vérany, 1846) (Fig. 33) (original description in Vérany 1846, detailed description in Schmekel and Portmann 1982), Calmella gaditana (Cervera, García-Gómez & García, 1987), comb. n. (original description in Cervera et al. 1987, = " Flabellina " confusa González-Duarte et al. 2008, original description in González-Duarte et al. 2008; for discussion see Furfaro et al. 2017), Calmella bandeli Marcus, 1976 (original description in Marcus 1976).

Remarks.

The genus Calmella was established by Eliot (1910) and since that time it has never been synonymised with Flabellina , until the most recent Furfaro et al. (2017) study. According to the present phylogenetic analysis Calmella is valid, related to the true Flabellina s. str. (Fig. 2) and differs morphologically regarding its much less ramified and raised ceratal stalks and presence of smooth rhinophores. See remarks also under the genus Piseinotecus .
