Another female S'kytri would appear in the Lost Tribe of the Sith - Spiral story arc from Dark Horse.  The leader of the Doomed is also a green-skinned S'kytri named Kaliska.  The Doomed are a group of Jedi descendants who lived on Kesh and oversee the imprisonment of the Dark Jedi Remulus Dreypa.

The Tate's Comics exclusive cover for Lost Tribe of the Sith - Spiral #1 shows Kaliska standing behind the Lightsaber wielding Takara.  Like Kharys, her head is mostly bald except for a mohawk-like tuft of hair down the middle.
