Crime drama True Detective and new online series Transparent have emerged as the top nominees for the 2015 Writers Guild Awards.

Transparent, starring Jeffrey Tambor as a transgender man, landed a trio of nods and will compete for the Comedy Series title with Orange Is the New Black, Silicon Valley, Louie and Veep, and the New Series category opposite Silicon Valley, The Affair, Clive Owen's The Knick and True Detective.

Transparent writer Ethan Kuperberg is also up for Episodic Comedy for The Wilderness.

The coveted Drama Series shortlist features House of Cards facing off with double nominees Game of Thrones, True Detective, Mad Men and The Good Wife.

Martin Scorsese and Mark Wahlberg's Boardwalk Empire was noticeably absent from the Drama Series nominations, as were Homeland and Fargo, but the period crime drama did land two mentions for Episodic Drama for the Devil You Know and Friendless Child instalments of the fifth and final season, which wrapped in the U.S. in October (14).

Likewise, Modern Family surprisingly missed out on the Comedy Series category, but did grab nods for The Cold and Three Dinners segments in the Episodic Comedy rundown.

Meanwhile, other nomination highlights include Saturday Night Live in the Comedy/Variety (Including Talk) - Series, The 68th Annual Tony Awards in Comedy/Variety - Music, Awards, Tributes - Specials, and the star-studded Tv movie adaptation of Larry Kramer's AIDS-crisis play The Normal Heart, which is up for the Long Form Adapted award, alongside Olive Kitteridge, Houdini and The Leftovers pilot.

The winners of the Writers Guild Awards, which honour the screenwriters behind the Tv hits, will be announced on 14 February (15).
