Inventario de Hymenoptera (Hexapoda) en El Ventorrillo: un rico enclave de biodiversidad en la Sierra de Guadarrama (España Central)

Hoverflies (Diptera: Syrphidae) of El Ventorrillo Biological Station, Madrid province, Spain: a perspective from a late twentieth century inventory

“…On the one hand, these results show how important long term surveys are even in a province whose hoverfl y diversity is thought to be well known (Ricarte & Marcos-García, 2017). On the other hand, the fi nding of 21 species new to Sierra de Guadarrama suggests the high potential of this location within the Iberian Peninsula for hoverfl y diversity studies, as shown by other insect groups (Lobo & Martín-Piera, 2002;Nieves-Aldrey et al, 2003).…”

“…The vegetation at the forest/grassland edge consists of various shrubs such as Cytisus, Crataegus, Rubus, Rosa, Cistus, Santolina, Juniperus, and Prunus, while in close-by areas outside the Station some patches of Quercus pyrenaica Willd. with Cistus shrubs occur (Nieves-Aldrey et al, 2003) (Fig. 2).…”

“…Highlands represent areas of endemicity and high biodiversity levels within the Mediterranean Basin (García-Barros et al, 2002;Reyero, 2002;Marcos-García et al, 2007). The Sierra de Guadarrama, located in central Spain, is one of the Iberian locations with the most signifi cant biodiversity (Lobo et al, 2001;Lobo & Martín-Piera, 2002;Nieves-Aldrey et al, 2003). For example, 1310 species of Hymenoptera are known to occur at El Ventorrillo (Madrid), a representative site within Sierra de Guadarrama, and in total 13000 insect species are estimated to occur at this single site (Nieves-Aldrey et al, 2003).…”

Its remarkable entomological diversity justifi es the status of part of Sierra de Guadarrama as a national park since 2013.…”

Los Chalcidoidea (Hymenoptera) asociados con agallas de Cinípidos (Hymenoptera, Cynipidae) en la Comunidad de Madrid

“…Otras aportaciones de material estudiado proceden de un proyecto de inventario entomológico de dos areas naturales de la Comunidad de Madrid (Estación Biogeológica de El Ventorillo, situada en la vertiente sur de el Puerto de Navacerrada, en la Sierra de Guadarrama, a unos 60 km al noroeste de la ciudad de Madrid y Monte de El Pardo en la zona de El Goloso, situada a unos 13 km al norte de Madrid), llevado a cabo entre los años 1988 a 1992, en su mayor parte colectados mediante trampas Malaise (Garrido-Torres & Nieves-Aldrey, 1999;Nieves-Aldrey et al, 2003), así como materiales procedentes de muestreos realizados con diversas técnicas, preferentemente red de barrido, por alguno de los autores en la Comunidad de Madrid (Garrido-Torres & Nieves-Aldrey, 1999).…”
