Forum Entomologi Italiani

One will refer to the bibliographies , descriptions and photos which I already gave with my messages, on the Forum, concerning the Tenthredopsis.

Ciao,

# 2458 captured at an altitude of 920 m. in Cne : La-Cluse-et-Mijoux (Dépt. Doubs - France) - 04.06.1992

This Symphyta is a Tenthredopsis ♀
Let us consider the keys of Blank & Ritzau :
One observe :
The Clypeus: Its form and the presence of a not very visible punctuation, are a problem.

- The Keys above can lead to T. sordida, however this species has an habitus completely differ.
Thus it should be considered that the clypeus is not regularly emarginated !

In addition :

- The sternites has 2 black lateral bands.
- The tergites are black, except the medians which are red orange.
- The tarsi 3 are in majority whitish , the base of their tarsomeres a little rosy.

That means that the capture would be T. stigma.

Thus :
Tenthredopsis stigma (Fabricius 1798) ♀ Che vive anche in Italia.
..... OK ?

Saluti.
