This is a very unusual case. I don't know how broad the ramifications are. But having a physical type specimen was always a requirement to get a new species name accepted by zoologists. (Two exceptions I know of: a bird that was examined and blood taken, so DNA was retained as the type specimen, and then the bird was set free: and one case (there may be more) using trails on the seafloor as evidence for an unseen invertebrate.)
Now we have a name accepted based on a photo with no DNA or body in hand. Cryptozoologists should not start jumping up with photos of Bigfoot because there is a caveat: the specimens were trapped and observed closely while being photographed, but escaped. This could get interesting.
