presumably Tenuidactylus fedtschenkoi (photo at night by Maxim A. Koshkin (copyright), unfortunately only photo we have; a bit pale due to flash, but a pale individual none-the-less). Similar to T. caspius but head rather plain and much smaller tubercles on dorsum. I did not examine it closely enough at time.
Habitat rocky hills/crags with little vegetation. c. 380m a.s.l.
Any thoughts much appreciated.
