%X Estudios de la biodiversidad existente en la zona intermareal rocosa del centro-sur de Chile, tanto de car芍cter local como regional, todav赤a son limitados. Debido a ello, no permiten el reconocimiento de patrones de diversidad a lo largo de la costa con una gran resoluci車n espacial, lo cual es informaci車n b芍sica al momento de priorizar 芍reas para la conservaci車n de la biodiversidad. En este sentido, el objetivo de la presente contribuci車n es estudiar la malacofauna de la zona intermareal rocosa del centro-sur de Chile, en un tramo de 250 km de costa, comprendida entre Punta Pingueral (36∼ 31'S) y Cabo Tir迆a (38∼ 25'S). Se estudiaron los moluscos de 23 sitios de muestreo, incluyendo las islas Santa Mar赤a y Mocha. En cada sitio se caracteriz車 el h芍bitat rocoso (morfometr赤a, tipo de roca, grado de exposici車n al oleaje, abundancia de arena intersticial, y 芍rea total de la superficie) y se realizaron muestreos exhaustivos de malacofauna en los niveles del intermareal superior, medio e inferior. Se registr車 un total de 90 especies de moluscos pertenecientes a 29 familias. Del total, el 61,1% son Gastropoda, el 25,6% Bivalvia y 13,3% Polyplacophora. Se discuten aspectos taxon車micos y se presenta una clave de identificaci車n de las especies Studies of the biodiversity of the rockyshore areas of the center-south of Chile, so much of local character as regional, they are still limited. Due to it, they don't allow the recognition of patterns of diversity along the coast with a great spatial resolution, which is basic information to the moment to prioritize areas for the conservation of the biodiversity. In this sense, the objective of the present contribution was to study the malacofauna of the rockyshore of the center-south of Chile, in a tract of 250 km of coast, among Punta Pingueral (36∼ 31'S) and Cabo Tir迆a (38∼ 25'S). The mollusks of 23 sampling sites were studied, including the islands Santa Mar赤a and Mocha. In each site the rocky habitat was characterized (morfometry, rock type, slope, abundance of interstitial sand, and total area of the surface) and out exhaustive samplings of malacofauna were carried (levels superior, medium and inferior of the rockyshores). A total of 90 species of mollusks belonging to 29 families were recorded. Of the total, 61.1% were Gastropoda, 25.6% Bivalvia and 13.3% Polyplacophora. A taxonomical discussion and a key of identification of the species is presented
