Abstract

A new spider crab, Eoinachoides bretoni n. sp. (Epialtidae MacLeay, 1838) from the Comfort Member of the Castle Hayne Formation (Eocene) of Onslow County, North Carolina (USA), is herein described, representing the second spider crab recovered from this member. Although the new species does not enlarge the stratigraphical range for the genus which is currently restricted from the Eocene to Miocene, it is the first report in North America, extending the palaeogeographic distribution of Eoinachoides, limited currently in the fossil record of South America. In addition, an updated list of the species of the Castle Hayne Formation is herein provided.

美国北卡罗莱纳古堡海恩石灰岩组(始新世)蜘蛛蟹一新属(短蛛目，蜘蛛蟹科)

本文描述了一种新的蜘蛛蟹，Eoinachoides bretoni n.sp.（Epialtidae MacLeay，1838），来自北卡罗来纳州昂斯洛县的Castle Hayne Formation（始新世）的Comfort Member，代表了从该成员中回收的第二只蜘蛛蟹。尽管新物种并没有扩大该属的地层范围，目前该属仅限于始新世至中新世，但它是北美的第一份报告，扩展了始新世的古地理分布，目前仅限于南美洲的化石记录。此外，本文还提供了海恩城堡组的最新物种列表。

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.
