摘要

描述了一种新的已灭绝的淡水腹足纲动物，Valvata mathiasi n.sp.，属于佩萨河谷（意大利中部托斯卡纳）上新世下沉积物中丰富的软体动物群落。这是该流域特有物种的又一个例子，增强了记录在案的淡水群落的高度特有性。然而，在那里采集的腹足类动物中，东部的亲缘关系在属和物种层面上得到了认可。

Valvata mathiasi n. sp. (Gastropoda: Heterobranchia: Valvatidae) from the Lower Pliocene of the Val di Pesa (Tuscany, Central Italy)

A new extinct freshwater gastropod species of the family Valvatidae, Valvata mathiasi n. sp., belonging to rich molluscan assemblages from Lower Pliocene deposits of the Pesa river valley (Tuscany, Central Italy), is described. This is a further example of a species local to that basin, enhancing the high endemic character of the recorded freshwater assemblages. Nevertheless, eastern affinities are recognised at genus and species level among the gastropods collected there.

期刊介绍： Archiv für Molluskenkunde (ISSN 1869-0963, e-ISSN 2367-0622); Up to and including Vol. 138/2 papers were published under the ISSN 0003-9284. rchiv für Molluskenkunde is an international, peer-reviewed journal on all aspects of molluscan biodiversity. It preferably publishes original research papers of high quality on systematics, taxonomy, phylogeny and morphology of all groups of molluscs, both recent and fossil from the Cenozoic. Contributions of broad international interest on other aspects of malacology such as ecology and biogeography are welcome as well. Papers on physiology, parasitology, regional faunistics or those on non-Cenozoic fossils or pure biostratigraphy should be submitted elsewhere.
