A Federation member species represented on Deep Space 9 in 2369 by the demanding Ambassador Taxco, one of the visiting dignitaries whom Julian Bashir is ordered to escort around the station.
The Arbazan are a humanoid people and a member of the United Federation of Planets. The only Arbazan seen on screen is Ambassador Taxco, who visits Deep Space 9 in the episode The Forsaken as part of a fact-finding delegation to the Bajoran wormhole.
Taxco travels with the Bolian ambassador Vadosia, the Vulcan ambassador Lojal and Lwaxana Troi of Betazed. She is quick to complain about her quarters and about almost everything Julian Bashir arranges for the party, and a colleague teases her about the reputed primness of her people.
When a computer malfunction causes a plasma fire in a corridor, Bashir saves Taxco and the other ambassadors by sheltering them in an access conduit, which finally earns him their praise.
