Carmelita

Hunter Queen Carmelita is a boss who will appear in the upcoming game Hollow Knight: Silksong. She appears to be an 'ant' queen, leading the tribe of ants seen in the reveal trailer.

In the trailer, she is fought in an auditorium with many balconies filled with ants spectating her fight with Hornet. One move can be seen where she leaps over Hornet, lands and creates spikes jabbing out of the ground from her point of landing. She also does a twirl of her two held blades after landing.

Due to her scene in the trailer; she matches the description of one of the bosses slated to be backer content, specifically the "operatic queen".

''For Silksong, backer content is again seamlessly integrated into the main game. Get ready to dance with operatic queens, battle mysterious assassins, scale a soaring warlord’s tower, and that’s just to start!''

For unknown reasons (most likely a typo) there are two spellings of the Hunter Queen's name: Carmelita in the file name on the press kit and Carmelitia on a blog post.
