Ctenobethylus
Ctenobethylus is an extinct genus of ants in the subfamily Dolichoderinae. The genus contains a single described species Ctenobethylus goepperti, where the fossil is known to be from the Baltic Amber. The fossil contained a preserved mesostigmatid mite attached to the head of the ant, which is perhaps the oldest known evidence of ecological association between mites and ants.
