“True Blood” star Mariana Klaveno has nabbed a recurring role on the upcoming sixth season of Showtime’s hit serial killer series “Dexter.” The brunette stunner will play a Florida University professor named Carissa Morris.

She joins season six recurrings Edward James Olmos (“Battlestar Galactica”), Colin Hanks (Lucky), Mos Def (Next Day Air), Molly Parker (The Wicker Man), Josh Cooke (Quarantine 2: Terminal), Billy Brown (Cloverfield), Aimee Garcia (“Trauma”)  and Brea Grant (“Heroes”).

Klaveno has guest starred on a number of popular TV shows including “Hawaii Five-O,” “Criminal Minds: Suspect Behavior,” “ER,” and ‘Alias.” She is best known, however, for playing vampire Lorena Krasiki (Bill Compton’s maker) on HBO’s “True Blood.” She was memorably killed last season when Bill twisted her neck a full 180 during sex.
