I've noticed something similar for multiple PC races listed in the Alien Archive: the NPC statblock has an ability not listed in the racial traits box for PCs. For example, dragonkin do not get a bite attack (or any natural attack for that matter), yet the NPC is listed as having a bite attack. This specifically bothers me for dragonkin, since it seems more fitting for them to have a natural attack than vesk do.
What am I missing here?
In the first encounter splat (don't have alliance archive yet) they say the the racial abilities listed for PCs are intentionally weaker than the full monster abilities. This is because it "allows us to present a wider array of potentially playable races, many of which would otherwise be too powerful." I expect that there is similar reasoning for any differences between the PC and NPC versions of races/species presented in the alien archive.

I suppose I can understand that. I might just institute a "feat adjustment" for these races to allow them to have that extra ability in the place of their 1st level feat.
