Faunistique des macrophyini de la Belgique et du Grand-Duché de Luxembourg (Hyménoptères : Tenthredinidae) : 2. Généralités sur le genre Macrophya DAHLBOM; inventaire des espèces apparentées à M. albicincta (SCHRANK)

Abstract

Les Macrophya DAHLBOM appartenant au groupe epinota sont représentées en Belgique et au Grand-Duché de Luxembourg par cinq des six espèces ouest-paléarctiques. Toutes sont associées au genre Sambucus LINNE (Caprifoliaceae). Une clé d'identification est donnée et la variation de certains caractères de M. alboannulata et de M. albicincta est étudiée et comparée aux données d'un échantillon d'origine française; l'hypothèse de la nature clinale de cette variation est avancée. La fréquence relative des espèces est la suivante : M. alboannulata, M. ribis, M. albicincta; toutes trois sont bien représentées et assez largement répandues. M. crassula, trouvée uniquement dans la seconde moitié du 19ème siècle, est fort probablement disparue. M. carinthiaca (KLUG), découverte seulement en 1964, n'a plus été retrouvée depuis 1969. Les caractéristiques de la période d'activité des adultes sont données et comparées à la situation décrite en France.

The species belonging to the epinota-group of Macrophya DAHLBOM, living in Belgium and Grand Duchy of Luxembourg have been inventoried. A key for their identification is given. Some aspects of the variability (coloration of scutellum, dimensions of wing's veins) between M. albicincta (SCHRANK) and M. alboannulata COSTA are analysed and compared with results obtained in France. This variability is perhaps of clinal type. From faunistical point of view, the geographical repartition, the phenology and the relative frequency of all species are related.
