Thanks J├╝rgen and John,
so this would leave at least four to chose from.
Is there any feature, apart from the genitals, which could distinguish those four options?
It is always good to know what to focus on for the next pictures to take. Especially since I am only taking pictures in the field and do no microscopic work.
Cheers, Lars
