[ES] En este artículo se presenta un estudio sobre los caräbidos (Coleoptera, Caraboidea) de la Sierra de Gredos (España central). Se realizaron 97 muestreos durante 3 arios y se visitaron 86 localidades. A partir de estos datos se ha elaborado un catálogo faunístico completado con el estudio de abundante material y datos bibliográficos procedentes de diversos autores. Se citan 260 especies incluyendo para cada una las localidades de procedencia, citas, si las hubiere, y su distribución general. La composición carabidológica de la Sierra de Gredos es muy similar a la del resto de las formaciones montañosas del Sistema Central: 63 'Yo de las especies de Gredos viven en Guadarrama y el 74,2 % en las sierras occidentales. El Sistema Central se manifiesta como una barrera biogeogräfica para un buen número de especies europeas y eurosiberianas, marcando su límite de distribución meridional y, en menor número, para especies mediterráneas y bético-riferias, marcando su límite septentrional. Aunque existe una clara influencia de tipo mediterráneo (43 %) en el área, en hábitats extremos (zonas elevadas) el número de endemismos aumenta considerablemente en detrimento de especies euritópicas de amplia distribución. Las especies más frecuentes y abundantes en este estudio han sido Calathus hispanicus Gautier, 1866, Nepha callosum (Küster, 1847) y Harpa/as decipiens Dejean, 1829. Durante el desarrollo del trabajo se describieron 5 nuevas especies de Gredos: 4 endógeas procedentes de las laderas sur: Typhlocharis carpetanus Zaballos, 1989, T. jeannei Zaballos, 1989, T. portilloi Zaballos, 1991, Geocharis julianae Zaballos, 1989 y un endemismo de las cumbres de la sierra, Platyderus jeannei Zaballos, 1990. Se citan por segunda vez en la Península Ibérica Dyschirius maroccanus Antoine, 1934, Trepanes (Diplocampa) clarki (Dawson, 1849) y Arriara (Zezea) strenua Zimmermann, 1831. Aunque casi todos los endemismos viven en el macizo central, en altitudes superiores a 1.900 m, destaca la riqueza faunística de dos enclaves: la vertiente sur con una rica fauna edafobia entre 300 y 600 m de altitud y la Sierra de la Paramera, con una rica fauna carabidológica de origen septentrional.
[EN] A study on the carabid beetles (Coleoptera, Caraboidea) of the Sierra de Gredos (Central Spain) has been carried out for 3 years, covering 97 samplings in 86 sites. From these data, a faunistic catalogue has been prepared, and subsequently completed with bibliographic data from several authors and the study of abundant material. Two hundred and sixty species are recorded, including for each of them capture sites, literature records, if available, and general distribution. The Sierra de Gredos has a earabidologic composition similar to the rest of the Sistema Central range: 63 % of the Gredos species live in Guadarrama and 74.2 `)/0 of them in the western mountain ranges. The Sistema Central is a biogeographic barrier for several European and Eurosiberian species, marking its meridional distribution limit, and, in a smaller number, for Mediterranean and Baetico-Riffian species, marking its northern limit. Although there is a clear mediterranean influence (43 %) in the area, in extreme habitats (high places) the number of endemisms increases considerably to the detriment of euritopic species, with wide distribution. In this study, the most abundant and frequent species were Calathus hispanicus Gautier, 1866, Nepha callosum (Küster, 1847) and Harpalus decipiens Dejean, 1829. In the course of this work, 5 new species from Gredos were described: 4 endogeous ones from the southern slopes: Typhlocharis carpetanus Zaballos, 1989, T. jeannei Zaballos, 1989, T. portilloi Zaballos, 1991, Geocharis julianae Zaballos, 1989 and an endemism from the range summits: Platyderus jeannei Zaballos, 1990. Dyschirius maroccanus Antoine, 1934, Trepanes (Diplocampa) clarki (Dawson, 1849) and Amara (Zezea) strenua Zimmermann, 1831 are recorded for the second time for the lberian Peninsula. Although most of the endemites live in the central massif, the faunistic richness of two special sites stands out for elevations over 1,900 m: the southern slope, with a rich edaphic fauna between 300 and 600 m, and the Sierra de la Paramera, with a carabidologic fauna of northern origin.
