Our capture has the Tegulae & the Legs entirely black.
Thus, it is a Dolerus
------
* Determination of species

Characteristics of our capture :

Body entirely black, except the Cenchri.
Antennae with segment 3 longer than segment 4 (see photo).
Sawsheat not widened to the apex.
The longest hairs of the Sawsheat are curved (curvature not null) on everything their length.
The angle α formed by the 2 tangents to the longest hairs of the Sawsheat (see photo) is obtuse.

Only 2 European species may have these characteristics or be confused, namely : fumosus & megapterus.
Sawsheat of megapterus (as the drawing from Haris) : All the hairs are curved and the distance between the apex of the longest hairs is short.
These 2 characteristics are not the ones of our capture, thus this one is the species fumosus (Was not captured in Italy)
[According to Haris this species is sporadic in Europe, and it seems that the south of Dépt. of Ain is the south limit of this species in Europe]
