* Determination of sub-Family Dolerinae, see :

viewtopic.php?f=370&t=21257&hilit=tenthredinidae

Our capture has : Tegulae entirely black and The apex of the Sawsheat exceeds the apex of Abdomen.
Thus, it is the Genus Dolerus
* Determination of species

Characteristics of our capture :

Thorax entirely black.
Femora & Tibiae all partially red-orange.
Abdomen entirely black.

Only 5 European species may have these characteristics or be confused , namely :
… gonager, gessneri, liogaster, puncticolis, albertii
We separate them by :
- The shape of the Sawsheat.
- The length of hairs of this one & of Cerci.

We see that our capture is the sp. gonager.
----
gonager was also captured in Italy
