Dira

From The Stargate Omnipedia

Inhabitant of the planet designated "177" who knew Atlantis expedition anthropologist Dr. Lindsay. During a Genii raid (disguised as a Wraith attack), Dira took Lindsay into her home for tea -- a welcoming custom in her society.

Dira was likely coerced by the Genii to distract Lindsay while the they set the stage to make it appear as though several expedition soldiers were killed in a fire. In reality the actual soldiers were taken away so that their Ancient gene therapy could be studied.
