The Cynipidae (Hymenoptera) of Comunidad de Madrid: checklist, distributional maps, species richness and conservation status

Abstract

Acheck list of the Cynipidae from Comunidad de Madrid (Spain) is presented for the first time. The data base contains 2189 records of samplings carried out from 1982 to the present in 103 sites in Madrid and 19 in nearby adjacent provinces. The list of 127 cynipid species from Madrid represents 73% of total Cynipidae species from the Iberian Peninsula. A distribution map in Madrid for each cynipid species is presented, showing the sampling sites where it has been found together with the potential distribution area of the species within the territory. Several aspects on the richness and distribution of the Cynipidae from Madrid are commented: potentially present and absent Iberian species, individual and rare species, and areas of high species richness. The area of highest richness for the Cynipidae of Madrid follows a strip of Cretacic and Tertiary soils along the Guadalix-Venturada-Torrelaguna axis, which also shows a high diversity of cynipid host plants, especially Quercus species. Other areas in SE Madrid deserving protection with regard to cynipids are also shown. These areas, some rich in rare and singular Aylacini species, other relictic areas with Quercus petraea in the Northeast and also some small areas with the presence of Quercus suber in parts of the territory of Madrid, deserve maximum protection concerning Cynipid conservation.
