Drahvin

Drahvins were a female-dominated humanoid race. Only a small number of males were kept alive for reproduction purposes, the rest being killed to preserve resources. Drahvin females were attractive, ruthless and aggressive. In the military, the soldiers are all grown in test tubes and the officers are all natural born.

History
One Drahvin ship battled a Rill ship and the two crash-landed on an uninhabited, doomed planet. The Drahvin leader, Maaga, tried to trick, then force the Doctor into helping them destroy the Rills and escape the planet, but failed. The Drahvins died when the planet exploded. (DW: Galaxy 4)

They attempted to invade Earth at some point prior to 1997. (NA: The Dying Days)
