摘要

摘要最近对智利北部新近纪沉积物的野外考察发现了新的材料，包括三种棘刺类植物Arbacia:来自中新世的Arbacia quyllur sp. nov，来自上新世的Arbacia terraeignotae sp. nov和Arbacia larraini sp. nov。在更新世，新材料包括现存种Arbacia spatuligera的首次化石发现和现存种Tetrapygyus niger的新标本。这里描述的标本和新种揭示了过去Arbacia属的显著多样性，并增加了我们对南美洲Arbacia属整体多样性的认识，显示了智利海岸Arbacia属的起源更早(中新世上)和物种丰富度比以前认为的要高。Resumen。在智利北部发现的新材料中，在智利北部发现的新材料中，在智利北部发现的新材料中，发现的新材料中含有equinoidea Arbacia quyllur sp. 11 (Mioceno)，在智利北部发现的新材料中含有equinoidea Arbacia larraini sp. 11 (Plioceno)，在智利北部发现的新材料中含有equinoidea . 11 (miloceno)，在智利北部发现的新材料中含有equinoidea . 11 (miloceno)，在智利北部发现的新材料中含有equinoidea . 11 (Plioceno)。Los especímenes y las nuevesespecies aquí描述了一种名为“varidsidad pasada del gassnero Arbacia”的植物。墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥

New Species of the Genus Arbacia (Echinoidea, Arbaciidae) from the Neogene of Chile

Abstract. Recent fieldwork on Neogene deposits of northern Chile led to the discovery of new material, including three new species of the echinoid genus Arbacia: Arbacia quyllur sp. nov. from the Miocene, Arbacia terraeignotae sp. nov., and Arbacia larraini sp. nov. from the Pliocene. In the Pleistocene, the new material includes the first fossil occurrence of the extant species Arbacia spatuligera and new specimens of the extant species Tetrapygyus niger. The specimens and new species described here reveal the significant past diversity of the genus Arbacia and increase our knowledge of the overall diversity of the genus in South America, showing an older origin (upper Miocene) and higher species richness of the genus Arbacia along the Chilean coasts than previously thought. Resumen. Recientes trabajos de campo en el Neógeno del norte de Chile han permitido descubrir nuevos materiales, entre ellos tres nuevas especies del género de equinoideo Arbacia: Arbacia quyllur sp. nov. (Mioceno), Arbacia terraeignotae sp. nov. y Arbacia larraini sp. nov. (Plioceno), pero también la primera aparición de Arbacia spatuligera y nuevo material de Tetrapygyus niger (Pleistoceno). Los especímenes y las nuevas especies aquí descritas revelan la diversidad pasada del género Arbacia. Estos descubrimientos muestran la existencia de una mayor riqueza de Arbacia a lo largo de las costas chilenas y un origen más antiguo del género en la costa del Pacífico Sureste (Mioceno superior).

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
