For all the Authors the coloring of Antennae (& Legs) is quoted in the first at all, but all do not see it in the same way !
* The Macek’s key does not envisage the intermediate characteristics (for example the Antennae are black or yellow to reddish).
- The coloring of Femora 3 is not significant.
The coloring of Sternite 7 is inaccurate for multifasciata (or is it the base of the Sexual Organs placed after ?)
- The criterion on the length of sub-apical tooth on Tarsi 3 is it reliable ?
All our french captures (in 6 departments : from the Oise to Jura) were made in woody or forest zones, except one.
It well seems that only the extreme colorings allow to identify with certainty the species.
* Antennae with Flagellum entirely black ==> multifasciata
... All have the ventral apex of Abdomen entirely red or very mainly red (as shows it the photo attached of multifasciata)
* Antennae with Flagellum partially black
... A single french capture : the ventral apex of Abdomen is entirely black (see photo)
* Antennae entirely yellow to reddish ==> xanthocera
Being color of the Sexual Organs, our capture is xanthocera (confirmed by 3 photos in http://www.boldsystems.org/index.php/Ta ... xid=339651)
----
NB : xanthocera & multifasciata have the same habitus

S. xanthocera & multifasciata was also captured in Italy
