Abstract

Icriobranchiocarcinus rodas Vega n. sp., is recorded from lower Maastrichtian (Upper Cretaceous) Arroyo Grande Formation near the town of Rodas (Central Cuba). I. rodas Vega n. sp. represents additional evidence of paleobiogeographic affinities between Chiapas (SE Mexico) and Cuba, during the Late Cretaceous. The genus Icriobranchiocarcinus Vega, 2018 in Vega et al., 2018 was erected from the type species Icriobranchiocarcinus tzutzu Vega, 2018 from the lower Maastrichtian Ocozocoautla Forma-tion (Chiapas). I. rodas Vega, n. sp. preserves details of ventral morphology as well as more details of chelipeds not reported in I. tzutzu, adding to the morphology of the genus. Icriobranchiocarcinus belong to a family (Lythophylacidae Van Straelen, 1936) that became extinct worldwide during the K/Pg event.

古巴白垩纪晚期（马斯特里赫特阶早期）的一种新的石纲螃蟹（甲壳纲、十足目、Portunoidea）

Icriobranchiocarcinus rodas Vega n.sp.，记录自罗德里格斯镇附近的下马斯特里赫特阶（上白垩纪）阿罗约-格兰德组。I.rodas Vega n.sp.代表了晚白垩纪恰帕斯州（墨西哥东南部）和古巴之间古生物地理学亲缘关系的额外证据。Vega et al.，2018中的Icriobranchiocarcinus Vega属，2018是由模式种Icriobranchioccarcinus tzutzu Vega，2018从下马斯特里赫特阶Ocozocoautla Forma tion（恰帕斯州）建立的。I.rodas Vega，n.sp.保留了腹侧形态的细节，以及I.tzutzu中未报道的螯足类的更多细节，增加了该属的形态。Icriobranchiocarcinus属于一个在K/Pg事件期间在全球范围内灭绝的科（Lythophylacidae Van Straelen，1936）。

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.
