Of course. 

Definitely viridis! 

Hi folk! by coincidence, i found this discusion and i want to put some important characteristics to separate L. viridis and L. trilineata. These two lizard species can be very difficult to distinguish at times, especially as both are very variable. However they can be easily distinguished from each other.

1. In L. viridis, the rostral plate typically does not in contact with nostrils. Whereas...
2. In L. viridis, typically there are relatively big scales (i.e. plates) in temporal region, so there only a few of them.
3. Also the supraciliary granules located between Supraocularia and Supraciliaria are interrupted/scattered and not forming a complete row in L. viridis. Whereas...
For copmarison i am attaching a Lacerta trilineata cariensis female here, showing all these chracteristics.. Now i am leaving the decision to you:)
All the best!
Cheers

in my opinion all these 3 characters are highly variable, so their value in identification is also poor... 

and I am waiting for L. t. cariensis, Bayram... 

In this way, i want to know which characters are stable in your view Tibor? Please let me know or elaborate this subject please!
On this issue i think i ve uploaded the L. trilineata from Izmir. But i think i am not familiar of this system:) Sorry my foresightless
 

Bayram,

First, you have to upload it, of course, after which it becomes visible in the "My photos" section of the answer page, below the sub-header "My forum photo uploads".
Then, you should insert the text "photo(NAME OF PHOTO AFTER UPLOAD TO THIS SITE)" in your answer, to enclose the photo.

I tend to agree with Tibor that -although certainly not useless- most of the traditional and well-known characters to distinguish between both species are susceptible to variation (including the also often mentioned number of belly scale rows). I am interested in anyone's answers, but in my opinion, there is NO clear-cut way to distinguish them across the entire range of co-occurrence.

The proportions of the head (or shape) of this animal, the number of temporal scales (also not 100% reliable) and the extent of blue, makes me think that this is viridis.

g's,

J. 

and if you see the whole animal I'm sure you will know for sure http://www.treknature.com/viewphotos.php?l=3&p=235196 ;-)

for me is Lacerta viridis meridionalis, male 

Hi again Folk,

Thanks Jeroen, i think i could uploaded this time:)
I have to admit that the bluish (it is better to say turquoise here!)colouration is also variable characteristics. You can see a real viridis colouration in Turkey from this link: http://www.trakus.org/kods_bird/uye/?fsx=2fsdl47@d&idx=36029 and also you could see a more developed bluish/turquoise colouration in an another L. trileata race galatiensis (http://www.trakus.org/kods_bird/uye/?fsx=2fsdl47@d&idx=35980), which is also sympatric with L. viridis and L. media media at the northern parts of Turkey (like Adapazari, Zonguldak and Kastamonu provinces).
Here i also attached the shots of L. t. cariensis from Izmir
Hope all are usefull.
Thank you for all:)

Female L. t. carienis

Male L.t. cariensis 

Thanks for the pictures, B.! Of course clear trilineata.

Most likely a "silly" argument, but I have the feeling that I can somehow tell them apart quite well by the type of blue... Let me also admit that my experience in Turkey is virtually non-existent.

Ilias just closed this case, in my opinion... 

+1 for the blue Jeroen! Some may argue that it's not reliable (and they may be right) but I,too,seem to recognize them by this pattern! 

May be you can not share my opinion but there is a common argument in Systematic Zoology that the pholidolial feautures are more stable criteria for the species discrimination and colouration feautures generally use for subspecies. Nice evening all!
Cheers 

Sure, Bayram. I would certainly not promote colour shade or pattern as trustworthy. It's just more of a jizz kind of thing. Pholidosis would generally receive more of my trust too, but there are several examples with lizards; e.g. the Iberolacerta spp. also are discriminated on criteria like "xx% of the population has this of that". In other words, thet represent a strong guidance, but appear not to be full proof?
