摘要

本文描述了西班牙西南部瓜达尔基维尔盆地(Gualdalquivir Basin)上新世沉积物中发现的一个介形虫新种——Cyprideis civis nov. sp.。这个新种的特点是体型小(长度小):塞浦路斯人(Cyprideis civis) 11 . sp.，生活在海底，沿海下古环境的沙质沉积物中，偶尔受到淡水通量和风暴的影响。在这种情况下，这个物种是腹足动物饮食的一部分，正如在瓣膜中发现的生物侵蚀痕迹所证明的那样。

Nueva especie de ostrácodo del Plioceno de la Depresión del Guadalquivir (S.O. de España)

A new ostracod species from Pliocene sediments of the Gualdalquivir Basin (SW Spain), Cyprideis civis nov. sp., is herein described and illustrated. This new species is distinguished in having small size (length: Cyprideis civis nov. sp. inhabited in the bottom, sandy sediments of an infralittoral palaeoenvironment, subjected to occasional freshwater fluxes and storms. In this scenario, this species was part of the gastropod diet, as evidenced by the bioerosion traces found in the valves.
