摘要

我们描述了一种来自韦斯卡省（西班牙阿拉贡）伊普雷西阶（始新世早期）罗达组的同盖蟹。尽管唯一标本的状况不完整，但一些保存下来的额骨元素，特别是完整的左螯肢，基于与该属现存物种的形态学相似性，允许将其纳入Wood Mason和Alcock，1891年的Paromola Wood Mason。与现存的Paromola cuvieri标本的直接比较（Risso，1815）证实了这一系统性的分配。Paromola bretoni n.sp.是伊比利亚半岛新生代报道的第一个同源动物，并扩展了比利牛斯山脉南部始新世盆地丰富的十足目化石记录。

First record of a homolid crab (Crustacea: Decapoda: Homoloidea) from the early Eocene of the Iberian Peninsula

We describe a new species of homolid crab from the Ypresian (early Eocene) Roda Formation of Huesca province (Aragon, Spain). In spite of the fragmentary condition of the sole specimen, some preserved frontal elements, and in particular the complete left cheliped, allow inclusion it within the genus Paromola Wood-Mason in Wood-Mason and Alcock, 1891, based on morphological similarities with the extant species of this genus. Direct comparison with specimens of the extant Paromola cuvieri (Risso, 1815) confirms this systematic assignment. Paromola bretoni n. sp. is the first homolid reported in the Cenozoic of the Iberian Peninsula, and expands the rich decapod fossil record of the Eocene basins of southern Pyrenees.

期刊介绍： The Boletín de la Sociedad Geológica Mexicana is a completely free-access electronic journal published semi-annually that publishes papers and technical notes with its main objective to contribute to an understanding of the geology of Mexico, of its neighbor areas, and of geologically similar areas anywhere on Earth’s crust. Geology has no boundaries so we may publish papers on any area of knowledge that is interesting to our readers. We also favor the publication of papers on relatively unfamiliar subjects and objectives in mainstream journals, e.g., papers devoted to new methodologies or their improvement, and areas of knowledge that in the past had relatively little attention paid them in Mexican journals, such as urban geology, water management, environmental geology, and ore deposits, among others. Mexico is a land of volcanos, earthquakes, vast resources in minerals and petroleum, and a shortage of water. Consequently, these topics should certainly be of major interest to our readers, our Society, and society in general. Furthermore, the Boletín has been published since 1904; that makes it one of the oldest scientific journals currently active in Mexico and, most notably, its entire contents, from the first issue on, are available online.
