Thank you, ChrisR. That it is necessary to see to say what this species ?

for species, the best would be to collect the specimen... otherwise is just a guess game.

With genera like
Gymnosoma a photo really doesn't show the subtle features that we need to make a species-level ID. Genitalia are fairly important but so is the facial and thoracic dusting and the relative length of thoracic hairs. Even with a specimen you have to manipulate them and view them under perfect lighting to obtain confidence in an identification.
The same goes for
Siphona spp., but for different reasons :)
