摘要

The taxonomy of Munida Leach, 1820 from the north-eastern Atlantic and Mediterranean Sea was studied using a comparative analysis of morphological characters and molecular markers (mitochondrial and nuclear). Generalized Mixed Yule Coalescence and the Poisson tree process models were used to delimit two groups of closely related species associated with uncertain nomenclature and taxonomic status: (1) Munida intermedia A. Milne Edwards & Bouvier, 1899, M. rugosa (Fabricius, 1775), M. sarsi Huus, 1935 and M. tenuimana Sars, 1872 and (2) M. rutllanti Zariquiey-alvarez, 1952 and M. speciosa von Martens, 1878. We found that M. tenuimana is restricted to northern Atlantic waters (north of approx. 48 degrees N), while Mediterranean and Bay of Biscay specimens previously assigned to this taxon actually belong to a different species, indicating that the name Munida perarmata A. Milne Edwards & Bouvier, 1894 should be resurrected. Furthermore, M. rutllanti is shown to be a junior synonym of M. speciosa, a species that has thus far only been reported along western Africa. In addition, three species are re-described and a key to European Munida is provided. The validity of the morphological characters used to distinguish the different species is discussed. Phylogenetic analyses revealed three independent lineages with unsolved relationships among them, including high genetic distances for some species. These findings indicate highly divergent lineages of the European Munida and several events of colonization along the eastern Atlantic.

Sarsi Huus，1935年和M. Tenuimana Sars，1872和（2）M. Rutllanti Zariquiey-Alvarez，1952和M.Compiosa von Martens，1878年。我们发现了M. Tenuimana仅限于北大西洋水域（北约大约48岁），而先前分配给这个分类群体的地中海和贝斯塔标本实际上属于不同的物种，表明村庄名称慕尼达·佩尔曼A. MILNE Edwards＆amp; Bouvier，1894年应复活。此外，M.Rutllanti被证明是M. Speciosa的初级同义词，该初级名称仅沿着西非沿着西非报告的物种。此外，还重新描述了三种物种，并提供了欧洲局部门的关键。讨论了用于区分不同物种的形态特征的有效性。系统发育分析揭示了三种独立的衬里，其中包括未解决的关系，包括某些物种的高遗传距离。这些调查结果表明了欧洲局部的高度不同的谱系，以及东部大西洋的几个殖民化事件。
