NARCISO, Samuel; PRIETO-ARCAS, Antulio  y  ACOSTA-BALBAS, Vanessa. Microgastropods associated with the natural bank of Arca zebra (Swainson, 1833; Mollusca: Bivalvia) located in Chacopata, Sucre State, Venezuela. Cienc. mar [online]. 2005, vol.31, n.1a, pp.119-124. ISSN 0185-3880.

The objective of this study was to analyze the taxonomy of microgastropods associated with the bivalve Arca zebra, an important fishing resource of the northern coast of Venezuela. The samples were obtained in the area of Chacopata, Sucre State, Venezuela. A total of 381 gasteropods were collected belonging to 25 species included in 12 families. The families with the highest number of species were Margellinidae (4), Collumbelidae (4) and Fisurellidae (3). Of the total of species collected, seven (Marginella haematita, Lucapina sowerby, Cantharus cancellarius, Crassispira tampanensis, Pyrgocytara coxi, Monilispira leusosyma and Terebra nasulla) represent new records for Venezuela, but can be catalogued as typical of the tropical western Atlantic.
