Ciao,

# 2449 ♀ captured at an altitude of 920 m. in Cne : La-Cluse-et-Mijoux (Dépt. Doubs - France) - 04.06.1992

This capture is Tenthredo s.l..
- The antennae are black and white.
- The abdomen is dorsaly entirely black and his 1st tergite is not stained with white.
It thus acts of the sub-genus Tenthredella.
- The lower face of antennae is strongly cleared up.
- The forewings are not infuscate towards the apex (if not : albicornis)
- The stigma is brownish (solitaria, having it yellow)
- The metapleura are stained with white (solitaria has 1 pale yellow crest on the episterna)
Nota :

solitaria ♀ typus has the abdomen dorsally black, & lateraly with a spot white, but the var. seeboldi Konow has the abdomen coloured like velox ♀ typus !

Finally :
Tenthredo (Tenthredella) velox ♀ Che vive anche in Italia

Saluti.
