Abstract

A new sacoglossan species of the genus Elysia Risso, 1818 from southern Italy is described based on its external morphology, color pattern, radular teeth, and reproductive system. Specimens of this new species were previously attributed to Elysia viridis (Montagu, 1804) because of morphological similarity, but maximum-likelihood and Bayesian analyses based on four genes (mitochondrial cytochrome c oxidase subunit I, 16S rRNA, nuclear 285 rRNA, Histone 3), including 28 additional species of Elysia from the Atlantic, showed that they are distinct. In addition, to determine the identity of these specimens, different species delimitation analyses [Automatic Barcode Gap Discovery (ABGD), General Mixed Yule Coalescent (GMYC), Bayesian Poisson Tree Processes, (bPTP)] were carried out. The molecular results support the validity of this new species of Elysia from the Mediterranean Sea, named Elysia rubeni sp. nov. This new species is characterized by a bright light greenish surface color due to the abundance of kleptoplasts. It can be distinguished by its bright blue specks and minute sparkling yellow dots scattered along the body, as well as its smooth and greyish rhinophores.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal BULLETIN OF MARINE SCIENCE due to its progression and the good impact it has achieved in recent years, according to the agency Scopus (SJR), it has become a reference in its field. In the year of publication of the work, 2020, it was in position , thus managing to position itself as a Q2 (Segundo Cuartil), in the category Oceanography. Notably, the journal is positioned en el Cuartil Q3 for the agency WoS (JCR) in the category Marine & Freshwater Biology.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.22. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:
