Monomorium ant, from China, taped to Frozen toy box

In winter 2021-2022 my wife ordered a toy from China, a character from the movie Frozen. She spotted an ant taped to the box. I asked Dr. Philip Ward what he thought it might be, and he thinks it’s a species of Monomorium.

According to Wikipedia, there are 18 species of Monomorium in China. Common ones include the pharaoh ant and Monomorium floricola.
