Natalie Chaidez is exiting to focus on development as Dailyn Rodriguez and Ben Lobato will take over as showrunners.

USA Network is bringing drama Queen of the South back for a fourth season — with a change.

Showrunner Natalie Chaidez has exited the Fox 21 and Universal Cable Productions drama to focus on development. Instead, Dailyn Rodriguez and Ben Lobato have been promoted to serve as co-showrunners and exec producers, replacing Chaidez. (Chaidez, it should be noted, replaced original showrunner Scott Rosenbaum.)

Rodriguez joined the Alice Braga cartel drama as a writer in season two, most recently serving as co-exec producer. Lobato, who joined as a writer in season one, most recently was supervising producer.

"After two incredible years working with USA Network at the helm of Queen of the South, I'm moving on to develop my own projects full-time with my friends at Fox and Fox 21 Television Studios," said Chaidez, who has an overall deal with the studio. "I will miss the QOTS familia and fans, but I am proud to pass along the baton and champion the growth of co-showrunners Dailyn Rodriguez and Ben Lobato."

Based on best-seller La Reina del Sur, Queen of the South ranks as Thursday's No. 1 scripted series on ad-supported cable in the 9 p.m. slot among the advertiser-coveted adults 18-49 demo as well as total viewers. Season three, which wrapped its run Sept. 13, averaged 2.1 million total viewers when factoring in seven days of DVR. David T. Friendly also exec produces.

Queen of the South is part of a USA Network scripted slate that also includes Suits and its forthcoming spinoff, anthologies The Sinner and Unsolved, Bourne spinoff Treadstone, The Purge and Mr. Robot. The renewal comes as USA Network's signature drama Mr. Robot will wrap its run with its fourth and final season in 2019. A decision on the future of Unsolved has not yet been determined.
