Beta Annari
The Beta Annari were a species of sentient reptiloids. 

This species possessed 1,253 olfactory receptor genes, which gave them an extraordinarily acute sense of smell; they could detect when another person was lying, what they last ate, and the identity of their last  partner. However, their sense of smell could be deceived by someone injected with beta-blockers, anxiolytics, and benzos.

One member of this species, Mr. Vup, worked as a bodyguard for Bjayzl on Freecloud. He inspected Rios as he posed as an interfacer brokering a deal with Bjayzl to exchange Seven of Nine for Bruce Maddox. ()
