Hello Gateside, I looked at the keys from Fonseca, then Hennig. I see what you mean now. I apologize for not reading the keys before. The discal vein is longer. I really didn't key it. Again, my apologies.

To be honest, i avoid British keys and res books because i find them to be melodramatic and too patriotic (usually contain data only useful to the homeland). For example, if you read British text about Pyrrhocoris apterus, the British text implies that one must find a lime tree in order to find the species. And scientifically, lime is a genus of many species of plants called 'lime' or 'linden'. Here in Berlin, i can find Pyrrhocoris apterus on the sidewalk right now as i type. Not a 'lime' tree in sight. I find them in sandy areas, on pine trees, etc. I stopped using those old res books a long time ago. You also do this: 'but mine is definitely dung from rare cattle'. The cattle is a rare breed and this breed of cattle is the only dung that it can be found upon? or the fly is rare? or the particular species is rarely found on cattle dung? I guess that i cannot understand most British disposition. I try to find alternative text. I really have trouble with res stuff. I am not German either, i just live here. English is my native language but i still don't understand 'but mine is definitely dung from rare cattle'.

Anyway, you are right (about the discal vein). I apologize for not making time to key this.

I hope that you have a pleasant day.
