Capture in Cne Les-Neyrolles (Dépt. Ain - France) - 07 VI 1995
======
Biblio (used) :
- Lacourt 1999 : Répertoire des Tenthredinidae ... - Mém. SEF n° 3 - 1999
- Wright 1990 : in “Field Studies Council n° 203” , British Sawflies ...

----------
To identify the species I did not take into account the number of cells closed on the hindwings, because the Authors (not quoted in the Biblio) are not all of agreement on their number !
As for the color of legs it is of the most fanciful !!
-------
Our capture is a Blennocampinae.
For determination of this sub-Family see viewtopic.php?f=370&t=21257&hilit=tenthredinidae
We see on the photo that :
- Abdomen black
- The Veins M & 1m-cu does not converge it one to toward the other.
- The Vein 3A is rectilinear.
These 3 characteristics brings us to the genus Stethomostus
---
2 species are present in Europe : fuliginosus & funereus
The characteristics of our captures are :
- Ratio of 4th antennal segment (Lenght/width) >2 [<2 for funereus]
- Legs 3 mainly black [reddish for funereus]

Of where the determination
---
Only fuliginosus was captured in Italy
