What is the binomial name of Box jellyfish?

Chironex fleckeri, I am sorry to say, is wrong. Chironex feckeri is the species of the box jellyfish not the species. I am still trying to figure out the genus of the box jellyfish for a school project. I am sorry if this is no use to you but I just thought I would tell you that you go misinformation. Thank you for your time.
