[ES] Se estudia una taxocenosis de calddidos pteromálidos (Hym., Pteromalidae) capturados mediante una trampa «Malaise» instalada a lo largo de 1988 en la Estación Biogeológica de «El Ventorrillo», situada en el sector medio de la Sierra de Guadarrama (España). Se colectaron 100 especies repartidas en un total de 404 ejemplares. 12 géneros y 40 especies resultaron ser nuevas para la Península Ibérica. Se analiza la estructura y dinámica temporal de la comunidad. Se concluye que ésta muestra altos índices de diversidad y uniformidad y bajo de dominancia. La distribución de frecuencias de las especies se ajusta a la serie logarítmica. Los valores más altos de abundancia, riqueza y diversidad se alcanzan en el período estival. Se analiza, por último, la estructura «gremial» de la comunidad. El porcentaje más alto está representado por el grupo de especies parasitoides de insectos gallícolas, minadores y enrolladores de hojas.
[EN] A taxocoenosis of pteromalid chalcid flies (Hym., Pteromalidae) collected with a Malaise trap in the Median Sector of the Sierra of Guadarrama (Spain) is studied. An amount of 404 specimens representing 100 species were collected. 12 genera and 40 species are new record for the Iberian Peninsula. The structure and dynamics of the community is analyzed. It shows high indices of diversity and evennes and low index of dominance. The frequency distribution fits the log-series model. The higher values of abundance, richness and diversity are reached in the summertime. Guild composition of the community is also analyzed. Main percentage is represented by the group of parasitoids of gall-forming, leaf-mining and leaf-folding phytophages.
