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.
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.
