Scientific name: Acanthacorydalis sp. Commonly seen Great Diving Beetles are brown to black, but this species has slightly reddish fangs. The size is also extra large. Since there are tears in the wings, I think it's better not to spread them. We apologize, but we do not guarantee against grade reduction due to transportation, so please understand. We will ship the pictured individual collected from Ruyuan, Shaoguan City, Guangdong Province, China. It was collected on 7/21. According to my measurements, the body length was about 146mm.
