I'm wondering if both Euproctus montanus wouldn't be males. The spurs are not always as pronounced (as e.g. in platycephalus), especially in non-breeding and/or subadult males. It's especially the broad head (or jaws) that makes me wonder. If you see my 2009 report, there's a full grown female, which shows the narrow head typical for females.
Great trip reports. I've already admired the grass snakes in Jeroen's report last year, very stunning animals. Sorry to see that this really nice looking blue specimen got run over by a car. And I have to say, that I really like the Brook Newts, they look pretty cool.
Maybe you are right Jeroen there is a hint of a spur and a bit of a bulge as seen on the pic below and the head on your 2009 specimen is certainly relatively smaller to the body.
The reason I labelled that one a female was because when I disturbed them with the torch they appeared to be interacting, but I guessing without checking the cloaca it is hard to tell apart with this species (which I foolishly didn't)..
