When the 70th Primetime Emmy Awards are handed out Monday night at the Microsoft Theater in downtown Los Angeles — with NBC carrying the ceremony live — some of the comedy categories are expected to be more wide-open than they’ve been in years.

That’s in large part due to “Veep” being on hiatus while star Julia Louis-Dreyfus undergoes cancer treatment. “Veep,” which has won Outstanding Comedy Series the past three consecutive years, is not nominated this year. Nor is Louis-Dreyfus, who won Outstanding Lead Actress in a Comedy Series the last six years in a row.

Also not nominated this year is ABC’s “Modern Family,” which was the juggernaut in the Outstanding Comedy Series category before “Veep” moved in. “Modern Family” won the award five consecutive years, from 2010-2014, before giving way to “Veep.”

That means the door is open in a way that it rarely has been lately for one of this year’s eight nominees to break through. Here’s the list of nominees for Outstanding Comedy Series:

“Atlanta”

“Barry”

“black-ish”

“Curb Your Enthusiasm”

“GLOW”

“The Marvelous Mrs. Maisel”

“Silicon Valley”

“Unbreakable Kimmy Schmidt”

Many observers see it as a race between “Atlanta” and “The Marvelous Mrs. Maisel,” with “Mrs. Maisel’s” Rachel Brosnahan the front-runner to take advantage of Louis-Dreyfus’ absence in the Lead Actress category.

Here are the nominees for Outstanding Lead Actress in a Comedy Series:

Pamela Adlon, “Better Things”

Lily Tomlin, “Grace & Frankie”

Allison Janney, “Mom”

Tracee Ellis Ross, “black-ish”

Issa Rae, “Insecure”

Rachel Brosnahan, “The Marvelous Mrs. Maisel”

All of the shows in the category are relatively new — none of them were on the air the last time Julia Louis-Dreyfus didn’t win in the category.

Here are the nominees for Outstanding Lead Actor in a Comedy Series:

Anthony Anderson, “black-ish”

Ted Danson, “The Good Place”

Larry David, “Curb Your Enthusiasm”

Donald Glover, “Atlanta”

Bill Hader, “Barry”

William H. Macy, “Shameless”

Donald Glover took home the trophy last year, and given the Emmys’ tendency to settle into a comfort zone, is seen as the favorite to repeat.
