Abstract

The true diversity of deep-sea benthic harpacticoid copepods of the Mexican Exclusive Economic Zone (MEEZ) is far from being known. Only 27 species have been described for this region. Previous studies on the US Gulf of Mexico and in other world's ocean basins have revealed that the harpacticoid family Pseudotachidiidae Lang, 1936 is one of the most abundant and frequent harpacticoid taxa in meiofauna sediment samples. The taxonomy of the Pseudotachidiidae is still controversial and there is no consensus regarding its composition and taxonomic position, and phylogenetic relationships amongst its constituent taxa. Here we describe four new species of Pseudomesochra Scott T., 1902 (Pseudomesochrinae Willen, 1996), P. bathyalis sp. nov., P. axa sp. nov., P. bathysicola, and P. bathyhabitatrix sp. nov., and a new genus and new species, Nuriaella mendezae gen. et sp. nov. (Danielseniinae Huys and Gee, 1996) from the deep-sea of the Mexican Gulf of Mexico and Gulf of California, along with a proposal of several species groups of Pseudomesochra.

Scott T., 1902（桡足目：Harpacticoida: pseudoachidiidae）在加利福尼亚湾和墨西哥湾深海发现的四新种，并提出了Danielsseniinae亚科新属和新种的建议

墨西哥专属经济区（MEEZ）的深海底栖类羽足类桡足类的真正多样性还远未为人所知。在这个地区只发现了27种。对美国墨西哥湾和世界其他海洋盆地的研究表明，1936年的harpacticoid family Pseudotachidiidae Lang是小型动物沉积物样本中最丰富和最常见的harpacticoid类群之一。伪足科的分类仍有争议，其组成、分类地位以及各组成类群间的系统发育关系尚无共识。本文描述了来自墨西哥湾和加利福尼亚湾深海的pseudoesochra Scott T., 1902 （pseudomesochrae Willen, 1996）、p.a bathyalis sp. nov.、p.a axa sp. nov.、p.a bathysicola和p.a bathyhabitatrix sp. nov.四个新种，以及Nuriaella mendezae gen. et sp. nov. (Danielseniinae Huys and Gee, 1996)，并提出了几个pseudoesochra种群的建议。

期刊介绍： Zoologischer Anzeiger - A Journal of Comparative Zoology is devoted to comparative zoology with a special emphasis on morphology, systematics, biogeography, and evolutionary biology targeting all metazoans, both modern and extinct. We also consider taxonomic submissions addressing a broader systematic and/or evolutionary context. The overall aim of the journal is to contribute to our understanding of the organismic world from an evolutionary perspective. The journal Zoologischer Anzeiger invites suggestions for special issues. Interested parties may contact one of the editors.
