subspecies would be an incorrect term. "color morph isn't"Might just be a different color morph/subspecies, emps can range quite a bit in color, especially the iridescence when you shine light on them. I've seen some that are reddish-brown and some nearly jade under bright lighting/camera flash.
Colorwise, sure. But the granulation on the claws is all wrong for a cavi. I had an H. Longimanus that kept that same maroon color for a few weeks after a molt.I think it's common for a Emperor to look like cavimanus after molting.. my emperor still has the reddish color 1-2 weeks after he molted. can I post a pic of mine here? nvm, i'll post it for reference only.
