Hello, this pic was taken by Miguel Yuste http://www.biodiv...ode=search

- In Segovia (C. Spain)
- 806m
- 5. june
- city garden

I have not detailed info about L. caesia nor L. latevittata, so I donīt know if they have those dark bands on thorax (?).

Gregor's keys say L. tigrina has a longitudinal stripe between the dark band of thorax and the scutellum, the description of L. tigrina says: "connected by means of a midstripe", and keys: "narrowly connected" does it mean it can be incomplete?? (Itīs very different from Fonseca's broad one, but that's an older book)

Faune de France's french keys don't include L. tigrina, but the pic of its L. notata seems the same than Gregor's L. tigrina, I suppose itīs a synonym).

Maybe my eyes are confused now, but it seems to me L. tigrina has the apex of M1 more curved than L. obsignata? Maybe casual.

Can I discard L. caesia and L. latevittata and consider itīs L. obsignata because the line is not complete?

Iīm so thankful for any help on this, thank you
