Hi experts,

Maybe this is a very stupid question (although they always told me, the only stupid questions were the ones never asked), but in IntKey they always talk about subapical cell. Is that the same as a discal cell?
IntKey says "with a more or less closed subapical cell (bounded by veins 3 and 4). If I say "without" it rules out Muscidae, but there are Muscids without a sharp bend in vein 4. So I'm out in the cold here. Can someone fill me in? Preferably with an image?

A million thanks,

Andr? Jas

Sorry, I'm trying but it's not easy.
