Area between the gena (or genal carina, if present) and the posterior margin of the compound eye, bounded ventrally by the malar sulcus and dorsally by the vertex.

Back to the back of the head rumble-on! So according to this definition the genal carina is actually limiting laterally the gena, and the genal space is not the part of the gena. So what is the gena and temple and where is the vertex? And how the hakkk will somebody able to solve this problem? MB: This translates roughly to 'the temple'. I do not like 'temple', sounds too weird. And this is not the back of the head, but the side of the head. In essence, the space between the posterior margin of the compound eye and the curve that seperates the side of the head from the back of the head. When a genal carina is present, this curve is very distinct (in fact, its a ridge, and turns from side to back in nearly 90 degrees). In other taxa with a gentle curve from the side of the head to the back, this distinction is reduced. This character was used to distinguish taxa which had their eye 'far away' from the posterior margin of the head from taxa whose posterior margin of their eye basically met the curve to the back of the head. Does any of this make sense???
