Green damselfly - Argia

Green damselfly - Argia
White Rock Canyon, Los Alamos County, New Mexico, USA
April 3, 2010
Size: 5 cm?
The first of three damselflies of different colors I saw today. I haven't been having any luck identifying them. This one seemed to be in rather high, dry habitat (though there could have been a stream close by for all I know).

Moved
Moved from Dancers.

Moved
Moved from ID Request. Thanks for the interesting comments! Next time I see one of these things, maybe I'll try for a shot of the "tail" or the mesostigmal plates (though those shots may involve better equipment).

Female, looks to be vivida
but not sure how to tell vivida from plana. William may know. Lat's wait for his comment.

 
In my opinion - Argia vivida/plana (female)
Abbott states in his Argia vivida Species Account that the female mesostigmal plates have to be examined to separate this species from an A. plana female.
In areas of overlap of these species ranges, where this picture was taken, the separation of females and immature males of A. vivida and A. plana is probably not possible from a photo.
This is just my opinion - a real expert might could identify this damselfly with certainty.
