Korshunova, Tatiana, Martynov, Alexander, Bakken, Torkild, Evertsen, Jussi, Fletcher, Karin, Mudianta, I Wayan, Saito, Hiroshi, Lundin, Kennet, Michael Schroedl, & Picton, Bernard, 2017, Polyphyly of the traditional family Flabellinidae affects a major group of Nudibranchia: aeolidacean taxonomic reassessment with descriptions of several new families, genera, and species (Mollusca, Gastropoda), ZooKeys 717, pp. 1-139 : 39

Orientella gen. n. Fig. 21

Type species.

Coryphella trilineata O’Donoghue, 1921.

Etymology.

After orientis (Latin, east), in reference to the predominantly Eastern Pacific range of the type species C. trilineata and further species included in the genus.

Diagnosis.

Body narrow. Notal ridge discontinuous. Cerata in several groups. Rhinophores annulated or tuberculated. Anterior foot corners present. Rachidian teeth with non-compressed cusp and distinct denticles. Lateral teeth denticulated without attenuated process basally. Distal and proximal receptaculum seminis. Vas deferens very short, expands into broad penial sheath with an additional glandular formation. Penis discoid with small papillae.

Species included.

Orientella (?) cooperi (Cockerell, 1901), comb. n. (original description in Cockerell 1901), Orientella (?) fogata (Millen & Hermosillo, 2007), comb. n. (original description in Millen and Hermosillo 2007), Orientella trilineata ( O’Donoghue, 1921), comb. n. (original description in O’Donoghue 1921). Probably this clade and genus includes more Eastern Pacific coryphellid species, since several undescribed species have already been reported from Chile ( Schrödl 2003).
