Conclusion From tick surveillance conducted in Missouri in 2019, only four tick species of medical importance were identified: A . americanum , A . maculatum , D . variabilis, and I . scapularis . In 2021 following an expanded surveillance, however, sampling did detect the invasive species H. longicornis . The main finding of our study was the establishment of a novel tick, H . longicornis , through active state surveillance. Our find- ing is important and will aid in increasing

awareness of this tick among environmental health professionals and potentially a ected populations, especially beef farmers. Overall, our study can increase awareness of the tick species present in Missouri—including new novel species—to educate the public about safety and preventive practices, as well as pos- sibly inform the development of diagnostic and treatment protocols. We support and rec- ommend that continuous state surveillance is needed to identify existing, novel, and emerg- ing ticks and tickborne diseases.
