Ciao,
# 2526 captured in Cne : Pontoise (Dépt. Val d'Oise - France) - july 08, 1992 - Lenght (included saw-sheath) : about 9.2 mm.
- Only this species of Arge has the saws-sheath shaped tongs
I have captured a set of males, but I do not know if they are berberidis or A. nigripes because I do not have understood if the marks visible on the abdomen are transverse striations

Questo Arge vive anche in Italia
Arge berberidis (femmina) - OK ?
Saluti.
