Abstract

A list of 43 species of sawflies coll ected in the region of Dinant (Belgium, Province of Namur; mid­ June 2006) is given. Six species of ( cuneifrons, Heterarthrus leucomela , Hinatara excisa, Hinatara recta, brevicornis and Pontania virilis) seem not previously to have been recorded in Belgium.

Nous donnons une liste de 43 especes de Symphytes recoltes dans la region de D inant (Belgique, Province de Namur; mi-Juin 2006). Six especes de TentJu·edinidae (Heterarthrus cuneifrons, Heterarthrus leucomela, Hinatara excisa, Hinatara recta, Pontania brevicomis et Pontania virilis) ne semblent pas a voir ete notees auparavant en Belgique.

Abstract

During the spring of 2008 and spring of 2009 aleate gynes of Lasius bicornis (FORSTER, 1850) were discovered in Awirs (Flemalle) and Elewijt (Zemst). Records of this species in Belgium and surrounding countries are very rare. We give comments on the habitat and ant communities at the sites where this species was actually rediscovered. Keywords: Formicidae, Lasius bicornis, faunistics

Au printemps 2008 et 2009 des gynes ailees de Lasius bicornis (FORSTER, 1850) etaient decouvertes aux Awirs (Flemalle) et a Elewijt (Zemst). Les captures de cette espece en Belgique et dans les pays avoisinants sont tres rares. No us donnons des indications sur 1'habitat et les communautes de fourmis presentes sur les sites ou cette espece a, en fait, ete redecouverte.
