Lissotriton, but which one?

[Jeroen Speybroeck]

They can be difficult, even while I am seeing both species in good numbers each year. Note that that PDF paper is not based on range-wide sampling.

So, it will stay forever as "Lissotriton sp." even if I think there are strong chances for it to be a palmate newt.

In the adults, helveticus has white tubercles on the underside of the hind feet, for vulgaris these are brown. Don't know if this holds for juveniles and I can't see in the pictures.

From what I can tell, they're not pale enough to be the typical helveticus... However, exceptions to this characteristic exist as well...

Yes, I would tend to agree, overall it looks most like vulgaris but it pays to be thorough!

Concerning tubercles,
I can find both (near Stuttgart) - almost dark tubercles in helveticus and pale tubercles in vulgaris.
Sincerely,

Imho, it sticks better with females.

Hi everybody !

As I'm far away now, that's not easy to stay updated but I try.

I found this picture on facebook (taken in France), that may suggest L.vulgaris but I can't be totally sure of myself, many things make me think it could be a strange L.helveticus.
Can you confirme?

Odd helveticus (((maybe hybrid))).
