This is a female eriwanensis. There are a number of differences in shape of the head, folidosis, coloration and pattern. I personally prefer the following characters - Frontal shiled - wide with narrow irregular or prolonged dark dot in darevskii, narrow with wide transversally widened ( triangular or a drop like) dark spot in eriwanensis. These characters alone may confuse one who is considering snakes from the larger geographic space (i.e. submediterranean), however of you know snakes are from Armenia, S Georgia or NE- Turkey this works. Verntral scales in darevskii are in general much darker than in eriwanensis, and the last one always has some pink wash, especially pronounced on its lips. In "darevskii" lips are white with few black areas. Other characteristics will involve numbers of verntrals, but this is more appropriate for decolorized preserved specimen and time consuming.
The data quality assessment is a summary of an observation's accuracy. All
observations start as "casual" grade, and achieve
"research" grade when
the iNat community agrees with the observer's ID, where an "agreeing"
identification is one that matches exactly or is of a child taxon of the
observer's ID. For example, if Scott says it's a mammal and Ken-ichi
says it's Homo sapiens, then Ken-ichi agrees with Scott.
the observation has a date
the observation is georeferenced (i.e. has lat/lon coordinates)
the observation has a photo
Observations will revert to "casual" grade if the above conditions aren't met or
the community agrees the location doesn't looks accurate (e.g. monkeys in the middle of the ocean, hippos in office buildings, etc.)
the community agrees the organism isn't wild/naturalized (e.g. captive or cultivated by humans or intelligent space aliens)

This has to be either V. eriwanensis or V. darevskii, right? Do you know how to tell these apart?
