Abstract

Eurytellina is one of the most common tellinid genera in the Western Atlantic. Eurytellina angrensis is a new species here described, from the Southeast Brazilian Coast (Rio de Janeiro, Sao Paulo and Santa Catarina states). It resembles externally E. punicea, E. alternata and E. tayloriana, differing mainly by more upward umbo, a thin shell, translucent and two reddish blotches, each one in posterior and anterior regions of external surface. Based on the searched anatomy, it could be inferred that E. angrensis processes large amount of material deposited or in suspension, based on the gill-palp ratio 1:1; the absence of one of external lamellae; the ventral channel above mantle edge; and the siphonal tentacles poorly developed.

巴西东南海岸一新种——绿蕨属，附解剖细节

Eurytellina是大西洋西部最常见的tellinid属之一。Eurytellina angrensis是这里描述的一个新种，来自巴西东南海岸(里约热内卢de Janeiro, Sao Paulo和Santa Catarina州)。它的外表类似于雄鳞棘球蚴、互生棘球蚴和泰罗棘球蚴，主要区别在于更向上的伞形，薄壳，半透明和两个红色斑点，每一个在外表面的后部和前部。根据搜索到的解剖结构，根据鳃与触须的比例为1:1，可以推断出angrensis处理了大量沉积或悬浮的物质;缺片:缺少一个外部片;地幔边缘以上的腹侧河道;虹吸触须发育不良。

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.
