----
* Determination of Genus & species

Characteristics of our capture :

Antennae with segment 3 longer than segment 4
Vein A2 curved
The Veins M & 1m-cu do not converge the one on the other one
Hindwings with one Cell 1M closed
Claws without inner Tooth (I could not to make a good photo)
Sawsheat without spine at apex (see photo), [the Genus Monardis has a spine (see drawing from Zhelokhovtsev)]

Only the Genus Eutomostethus has these characteristics.

And these are identical to the diagnosis of luteiventris by Zhelokhovtsev : Abdomen yellow (NB: rather red-orange), basally and apically black, with dorsal longitudinal black stripes.
[The other species of Genus have the Abdomen entirely black]

Of where the determination.

luteiventris was also captured in Italy mainland & Sardinia
