Lyris

From Memory Alpha, the free Star Trek reference.

Lyris was a Taresian, one of the leaders of the nearly all-woman planet Taresia. She persuaded Harry Kim that he was a long lost Taresian, when in reality he had been infected with Taresian DNA to make it appear that he was becoming a Taresian. This was the way Taresian woman propagated their species. They would extract DNA from their male victims, killing them in the process. (VOY: "Favorite Son")

Lyris was played by actress Deborah May
