Abstract

The family Fasciolariidae contains important members of shallow coastal waters and sandy substrates fauna, with 24 species distributed among seven genera in Brazil. The taxonomic position of the family is well established in the Buccinoidea Superfamily, however, its arrangement among the different genera is still not known, mainly because no thorough taxonomic analysis has been undertaken. Because of the morphological similarities, families included in Buccinoidea are not consensual in its position, and the scarce anatomical knowledge of individuals grieves this situation. In the few phylogenetic studies, Fasciolariidae is usually recovered as monophyletic; however, other families such as Buccinidae are not. While molecular studies are widely used, few have a primal focus on the Buccinoidea superfamily, while none have fasciolariids as ingroups. The use of molecular phylogenetics, in a combined molecular/morphological analysis have proven useful in delimiting groups more internal to the tree, while the use of direct optimization and dynamic homology implemented in the computer program POY prove to be helpful when combining these distinct datasets. As a means of determining the phylogenetic position of Fasciolariidae and its genera, a more rigorous morphological assemblage of characters is needed in order to ascertain an appropriate analysis. In view of such needs, it is intended: 1) perform a combined morphology/molecular phylogenetic analysis of Fasciolariidae, based on species deposited in the National Museum of Natural History, Paris (MNHN) and Museum of Zoology, University of São Paulo (MZSP), as well as those acquired in loans from other institutions in the USA such as the Museum of Comparative Zoology, Harvard University, Cambridge (MCZ), American Museum of Natural History, New York (AMNH) and the National Museum of Natural Hystory, Smithsonian Institution, Washington D.C. (NMNH) and Academy of Natural Sciences of Philadelphia (ANSP), as to accomplish an apt amount of taxa needed for this study. 2) Acquire morphological knowledge of species belonging to key genera that are not present in collections in Brazil; and 3) assay bibliography relevant to the study in the visited institutions. The current project is intended to be performed for a period of 10 months in MCZ, Cambidge USA. (AU)
