摘要

在这里，我们报告了来自意大利北部中新世 "Calcari a Lucina "碳氢化合物渗漏矿床的 33 个软体动物物种。其中描述了 3 个新物种：腹足类的新种 Putzeysia diversii，双壳类的新种 Miltha (sensu lato) romaniae，以及分类亲缘关系不确定的异齿双壳类的新种 Sisonia ultimoi。在开放命名法中描述了 14 个物种。常见但神秘的腹足类物种 Phasianema taurocrassa 在此被认为属于 seguenzioid 属 Cataegis。大多数腹足类物种是深海海底的普通居民，并不局限于（必须）碳氢化合物渗漏的地点。腹足类的 Putzeysia diversii sp.nov.和双壳类的 Sisonia ultimoi sp.Putzeysia 属在地理上仅限于东北大西洋和地中海，而 Sisonia ultimoi sp.

Mollusks (Gastropoda, Bivalvia) from Miocene cold-seep deposits in northern Italy: revisions and additions

Here, we report on 33 molluscan species from Miocene ’Calcari a Lucina’ hydrocarbon-seep deposits in northern Italy. Three new species are described: the chilodontaid gastropod Putzeysia diversii sp. nov., the lucinid bivalve Miltha (sensu lato) romaniae sp. nov., and Sisonia ultimoi sp. nov., a heterodont bivalve of uncertain taxonomic affinity. Fourteen species are described in open nomenclature. The common but enigmatic gastropod species Phasianema taurocrassa is here suggested to belong to the seguenzioid genus Cataegis. Most gastropod species are inhabitants of the deep-sea floor in general, and are not restricted (obligate) to sites of hydrocarbon-seepage. The gastropod Putzeysia diversii sp. nov. and the bivalve Sisonia ultimoi sp. nov. are the geologically oldest members of their genera known to date. While the genus Putzeysia is geographically restricted to the NE Atlantic Ocean and the Mediterranean Sea, Sisonia ultimoi sp. nov. represents another link of the Miocene Mediterranean seep fauna to that of the central Indo-West Pacific Ocean.

期刊介绍： EJT is a fully refereed, international, fully electronic Open Access journal in descriptive taxonomy, covering subjects in zoology, entomology, botany (in its broadest sense), and palaeontology. EJT-papers must be original and adhere to high scientific (content) and technical (language, artwork, etc.) standards. Manuscripts that are clearly substandard in either of these categories will not be sent out for review. EJT is supported by a consortium of European Natural History Institutes, but its scope is global. Both authorship and geographical region of study need not be European. Authors are, however, strongly encouraged to involve European Natural History collections by consulting material or by depositing specimens (e.g. types and figured material) related to their published paper in the collection of a European Natural History Institute.
