Comparative descriptions

Recently I've "finished" the Apodrosus argentatus morphological description and I'm using it for describe A. wolcotti. When changes are being made, it is necessary to go back into A. argentatus traits. This way, new characters are appearing by comparison. The problem, maybe you can become excesively meticulous on the descriptions... but really, until now I can't know when stop!

Here a sample of "new" characters: Male tergites VII & VIII; Sternum VII


Anterior and posterior margins, the sculpture of surface, the projections... all are becoming important because they vary, but only by comparison it is clear.
