Hi Val. thanks for the information. Sorry if i was not clear, i was speaking about a morphological or patern criteria for difficilis, for wich you look quite shure.

Here the aculeus of the 2 individuals:
First one, damaging maybe during the process, is from the "difficilis"


Barneix G. : France : Le Monêtier-les-Bains : 05220 : 06/03/2026
Altitude : 2250 - Taille : 4 mm
Réf. : 371917

The second is from the second one, wich could be achyrophori or guttella ? Or still doronici for you ?
