Ribautodelphax vinealis Bieman, 1987 ( Fig. 2 E)

First record from Switzerland: Ticino, Mendrisio, Rancate, vineyard [45 ° 52 ’ 23.29 ’’ N, 8 ° 58 ’ 3.38 ’’ E, 343 m], 1 ♂,0 3.08. 2011, D-vac, leg. &det. Valeria Trivellone .

Second record from Switzerland: Ticino, Mendrisio, Somazzo, vineyard [45 ° 52 ’ 37.53 ’’ N, 8 ° 59 ’ 30.34 ’’ E, 537 m], 1 ♂, 26.04. 2011, D-vac, leg. &det. Valeria Trivellone .

Distribution:Netherlands, Finland (Södermann 2007), Norway (Söderman et al. 2009), Germany, Switzerland.

Remarks:both specimens were collected inside vineyards on wild vegetation of embankments. This species is known from the Netherlands to be monophagous on Brown bent ( Agrostis vinealis )in sandy dry grassland (Bieman 1987 b). In the present study aquantitative vegetation sampling at the above-mentioned sites revealed the presence of black bent ( Agrostis gigantea )and creeping bent ( Agrostis stolonifera )which are closely related to A. vinealis .
