congratulations I just have a look at your Flickr page and it's really great.
In my opinion this male should be Chrysis tristicula Linsenmaier (= Chrysis succincta succinctula sensu Linsenmaier 1959).
Chrysis gribodoi has a different shape of the hear posterior to compound eyes and different apical margin of the last tergum, more or less sinuate and concolour with rest of T3.
