Tenthredo balteata, northern Norway 05.07.2016

Hello, I've found this Tenthredo female in Bodø, northern Norway 05.07.2016. Size is close to 12 mm.
I get to Tenthredo balteata in the keys I have (because it has black pterostigma, but size is a bit too much, max. is 10 mm in the descriptions in for example Benson's key). I've also checked with descriptions on this page (in Norwegian!): http://www.biodiversity.no/Pages/162659

Is T. balteata correct or could it be a form of Tenthredo ferruginea?

Hello,

Your capture is not ferruginea because the Pterostigma is always light yellow and there is no variety with Pterostigma brown / dark brown even black.
It is Tenthredella balteata
