d'accord avec
Ferdinandea.
En principe il y à que
Ferdinandea cuprea ou ruficornis chez toi.
--- arista red-brown to orange; haltere knob yellow; mesanepisternite 2 pale-haired (some strong, black bristles also present) (stigma entirely pale yellow or bicoloured, with a brownish stripe between vein R and the apex of vein Sc; tergites varying from non-metallic, shining black to rather brassy; tergites 2 and 3 each with a posterior matt, black, transverse black bar, that is often quite faint) ....................................................... ruficornis (Fabricius)
--- antennal colouration varying from all segments entirely yellow to predominantly grey-brown, with the ventral half of the third segment yellowish and the first two segments more-or-less black; the two longitudinal stripes of grey dusting on the mesoscutum very pronounced throughout their length, reaching its posterior margin; stigma entirely yellow (orbital strip narrower) ............................................................................................ cuprea (Scopoli)
L'argument de la couleur de l'arista me semble difficile à juger, parce que trop dépendent de la lumière.

La seule photo de
ruficornis chez LMDI me semble une détermination douteuse vu la surexposition du sujet.
Le notum du mâle me semble très sombre, mais c'est quand-même un
Ferdinandea.
