necrocanis
In theory or from reading, I think true perruno is hardly distinguishable or in any way distinguishable from Leiarius marmoratus / longibarbis externally, apart from the ray count, which seems to tell them apart.
Again I would have to refresh my memory but I believe perruno has 10-11 rays dorsally while marmoratus has 12-14. I could totally be wrong because I'm pushing my memory back like 10 years
Thanks for your info. But still confused about it. I may be stupid haha but i can simply call it marmoratus then?
