Is it a new species? Or, it is a subspecies of C.fowleri?
It really hard to say, because their body shape is nearly identical, and their body marking pattern is very similar too.
What I figure out about how to tell the different between them is:
C.fowleri has less black dot on the side, and its side marking is from the foward part of the dorsal fin extend back to the caudal peduncle. The base color is more shallow.
C.coriatae has more irregular black dots on the side of body (especially the males) and the side marking is from the *base of dorsal fin and extend to the caudal peduncle.
Here is a picture of two species together.

The one in front is a female C.coriatae and the one behind is female C.fowleri.

Here is a young male C.fowleri
In addition, my friend told me that C.coriatae's side mark has C shape. and it is the way to tell different between this two species, but I saw numbers of C.coriatae don't have that C shape marking.
Anybody have any ideas? We can discuss here.
Thanks for replying.
