Tyler Posey is still the wolf of MTV…

The cable network has renewed its hit series Teen Wolf, starring the 22-year-old half-Mexican actor, for a fifth season.

The upcoming 20-episode season will be split in two parts, similar to the way the supernatural high-school series aired in Season 3, which also was super-sized (24 episodes).

Seasons 1, 2 and 4 each have consisted of 12 episodes running continuously.

Based on the Michael J. Fox-starring MGM movie, Teen Wolf was developed by Jeff Davis. The show has become a hit online, where fan tweets about it routinely put it in the Weekly Top 10 of Nielsen’s Twitter TV ratings, one of only two or three scripted shows to grab one of those spots regularly.

Posey stars as Scott McCall, the title teen werewolf character.
