La Sierra de Aroa (estado Yaracuy), es un sistema montanos.o aislado localizado en laCordillera de la Costa, Venezuela. Aunque posee pocos trabajos sobre fauna, se considera un area conun alto nivel de endemismo de vertebrados. Pese a su importancia, no existen estudios que reportensu mastofauna general. Aqui se presentan los resultados taxonomicos de los mamiferos de este sistemay se justifica la importancia de su conservacion. Para ello, se compilo informacion proveniente defuentes bibliograficas, bases de datos de museos y se realizaron dos salidas de campo. Se aplico unesfuerzo de captura de 3000 trampas-noche, 200 baldes-dia y 320 mallas-noche, en conjunto conregistros basados en avistamientos ocasionales, observaciones indirectas, 240 camaras trampa-dia yentrevistas a pobladores locales. Al menos 131 especies habitan el area, que representan el 31,8 % delas reconocidas a nivel nacional. De ellas, ocho especies son endemicas de Venezuela. Chiroptera fueel orden mas diverso, seguido de Rodentia y Carnivora. La alta representatividad de mamiferosencontrada, respecto al total de la biorregion y del pais, junto con su alto nivel de endemismo,aislamiento topografico y ubicacion, constituyen aspectos que resaltan el valor de esta area desde elpunto de vista de conservacion. Abstract . The Sierra de Aroa is an isolated mountain range in the Cordillera de la Costa, Venezuela.Although only a few biological surveys of vertebrates have been conducted in the Sierra de Aroa, it isconsidered as an area of high endemism; however, the mammalian community of the Sierra de Aroaremains poorly known. Herein we report a list of the mammals of the sierra, which we made based ona literature review, and museum and field work. The capture effort was of 3000 trap-nights, 200bucket-nights with two pitfall trap systems and 320 mist net-nights, together with direct-indirectobservations, 240 camera traps-day and interviews to locals. At least 131 species inhabit the Sierra deAroa, representing 31.8 % of the mammals known to occur in Venezuela. Of these, eight species areconsidered endemic to the country. Chiroptera was the more diverse order, followed by Rodentia andCarnivora. The high richness of mammals found with respect to that of the bioregion (Cordillera dela Costa), along with its high level of endemism, isolation and geographical location, are aspects thathighlight the value of the Sierra de Aroa from the point of view of conservation.
