Petarian

The Petarians are a spacefaring species.

Kasidy Yates and the Xhosa crew were working for the Petarians in 2371. Yates commented to Benjamin Sisko that the Petarians made her use outdated technology such as mark five transporters. 

Yates was still working for the Petarians in 2383 and they had not outfitted the Xhosa with a more up-to-date transporter system at that time.
