That particular emote is only seen in cutscenes and is not actually available to use in the open world. Every race seems to have their own version of the emote. Miqo'te males do the weird paw thing that looks similar to the female Miqo'te's /shocked emote, but is not actually the same. Female Miqo'te throw their palms up in a "dont shoot!" fashion. I'm not sure what the other races do but I assume the emotes are roughly similar.
You can see the male miqo'te emote in question here at 2:00...
And the female miqo'te version here at 2:08...
Again, neither emote is available for use in the game, though it does pop up in various cutscenes throughout the game. Here's the fem Miqo'te /shocked and /surprised for further confirmation:
*Note in the female /shocked emote (top pic) the hands are curled inwards, while the male Miqo'te's hands are oriented forwards in the cutscene emote. Also he throws his weight onto one leg for balance while the female's legs stay together.
