A tropical Atlantic species of Melibe Rang, 1829 (Mollusca, Nudibranchia, Tethyiidae).

Espinoza E, Dupont A, Valdés A - Zookeys (2013)

Bottom Line: The four residue deletions in the cytochrome c oxidase subunit 1 protein found in all previously sequenced tropical species of Melibe sequenced (and Melibe rosea) are also present in this new species.These deletions do not appear to affect important structural components of this protein but might have fitness implications.This paper provides the first confirmed record of Melibe in the tropical western Atlantic Ocean.

ABSTRACT
A new species of Melibe is described based on two specimens collected in Florida. This new species is well differentiated morphologically and genetically from other species of Melibe studied to date. The four residue deletions in the cytochrome c oxidase subunit 1 protein found in all previously sequenced tropical species of Melibe sequenced (and Melibe rosea) are also present in this new species. These deletions do not appear to affect important structural components of this protein but might have fitness implications. This paper provides the first confirmed record of Melibe in the tropical western Atlantic Ocean.

Mentions: The combined analysis of the three genes (H3, 16S, and CO1) produced a consensus Bayesian tree in which the monophyly of Melibe is well supported, posterior probability (pp) = 1 (Fig. 1). Within Melibe, the temperate species Melibe leonina is the most basal, however this result must be taken cautiously as several other species were not included in the analysis. For the rest of the species analyzed, Melibe arianeae sp. n. is sister to the tropical Indo-Pacific and South African taxa (pp = 1), which includes the Mediterranean non-native Melibe viridis as well as Melibe engeli, the species morphologically more similar to Melibe arianeae. All the species with more than one specimen included in the analysis (Melibe digitata, Melibe viridis, Melibe rosea and Melibe engeli) are monophyletic and well supported (pp = 1).
