Spanish team HRT does not feature on the 2013 entry list, amidst reports that the team will be closing next week.
The deadline for teams to submit entries for the 2013 season passed on Friday, with the published list of entrants featuring only 22 cars.
HRT team members have reportedly been made redundant following the Brazilian Grand Prix, after owners Thesan Capital failed to find a buyer for the team after publicly putting the team up for sale prior to the United States Grand Prix.
With HRT set to close down shortly, they become the first F1 team to shut down since Super Aguri in 2008.
HRT's demise also leaves Marussia as the only client for engine supplier Cosworth.
The entry list offers little other surprises, with world champion Sebastian Vettel taking the coveted #1 for a third successive season in 2013. Fernando Alonso will drive Car #3, while Sergio Perez joins McLaren as Car #6. Lewis Hamilton has also provisionally been given the #10 as he moves to Mercedes.
The list also confirms that Valtteri Bottas joins Pastor Maldonado at Williams.
No drivers have been listed at Sauber, Force India, STR, Caterham or Marussia, although after recent announcements there remains only a free seat at Force India, Caterham and Marussia respectively.
Lotus have also left car #8 TBA, although 2012 driver Romain Grosjean is expected to be given the nod alongside Kimi Raikkonen.
