Forum Entomologi Italiani

Hi all, is this one Systropha curvicornis or planidens? I can't really tell base on the key for the species and I only had this female (no males unfortunately). The lenght from the tip of the mandibles to the tip of the abdomen is ~ 12 mm

I caratteri per separare le femmine delle due specie:

1 Troisième article antennaire aussi long que les quatrième et cinquième ensemble.
Abdomen pas particulièrement large. 8-9 mm. ..............S. curvicornis (Scopoli)
- Troisième article antennaire plus court que les quatrième et cinquième ensemble.
Abdomen particulièrement large. 10‑11 mm. .................S. planidens Giraud

Ciao
Giuseppe

Thanks a lot for your help!
The lenght of the 3rd antennal segment is the same as the 4 and 5 combined, so this should be a female of Systropha curvicornis
