Term vertex
Explanation Quote from the Manual of Nearctic Diptera:
The median portion of the upper extremity of the head, bounded by the eyes latterally, the occiput posteriorly and the frons anteriorly, ...

Thus it becomes a rather roughly defined area you could call the posterodorsal margin of the head, in the middle of which you will find the (posterior part of) the ocellar triangle.

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
