Descripción
The Cretaceous conchostracan faunas from southern South America are poorly known, only five species were described from Argentina and Uruguay. In contrast, more than twenty seven species were reported from Brazil since the end of the 19th century. In this paper, Euestheria sp. A from the La Amarga Formation (Lower Early Cretaceous – Late Hauterivian to Barremian) in Neuquén Basin is re-studied and assigned to the genus Pseudestherites Chen. This finding found represents the sixth record of the genus in the world and the firstsecond outside China. This study increases the Cretaceous conchostracans knowledge from southern South America and brings more evidence about the close relationship among the ssouth american, african and asiatic conchostracan faunas.
As conchostracofaunas cretáceas do extremo sul da América do Sul são pouco conhecidas. Somente 5 espécies foram descritas para a Argentina e Uruguay. Entretanto as faunas do Brasil são conhecidas desde o fim do século XIX tendo sido descritas mais de 27 espécies. Neste trabalho se redescreve Eustheria sp. sp. A proveniente da Formação La Amarga (Cretáceo Inferior – Hauteriviano superior a Barremiano) da bacia Neuquina, atrobuindo-a ao gênero Pseudestherites Chen. Este achado representa o sexto registro do gênero a nível mundial e primeiro fora da China. Com este estudo, se aumenta o conhecimento dos conchostráceos cretáceos sulamericanos aportando novas evidências sobre a estreita relação existente entre as faunas sulamericanas e asiáticas
