Eurasian Newts (Triturus, former Triturus, Calotriton & Euproctus).. Triturus and its relatives (Ichthyosaura/Mesotriton, Lissotriton, and Ommatotriton) are a diverse and widespread group of newts. While mainly European, several species can be found in the Near and Middle East. Euproctus, the brook newts, are confined to Corsica and Sardinia.

Default Identification by belly pattern

Can the belly patterns and colours of the similar Triturus species, especially the females, be used as an indentifier as to which is which?

Hello !

That seems difficult to me.
I remember the variuous patterns among individuals of a single population.
In the 80's, a guide showed illustrations of typical patterns of cristatus, carnifex, dobrogicus and karelini, but now with newly described ivanbureschi and macedonicus, I'm not sure it remains relevant.

If belly patterns can't be used, is there a definitive to differentiate between female crostatas and karelinii?

Well, if you have only cristatus and/or karelinii, you can trust the throat :
- dark with wight fleckes for cristatus, dobrogicus, carnifex, macedonicus,
- orange/red like the belly, with black dots, for karelinii, ivanbureschi


There are good picture in :
