This ray is from Peru?Miles;1295162; said:
I would say P. sp. Peru.
From a species sight it may be a P. orbignyi, some morph of P. orbigny show ocelli. But it is not for shure that P. orbignyi lives in Peru.
And names on a exporter list may be peruvian motoro, histrix.
Did I miss something
peru sp's are everywhere for sale here
how big can they get ? and somebody have a adult pic ? i saw one on potamotrygon-forum but i want to see another pic

Yep it's from Peru.. It was sent to me as Motoro 'Common', however, before I corrected my exporter.. he was labelling these fish 'Histrix'..
Would you consider these to be Orbignyi? This group contains 3 peruvians 'Laticeps' and 3 peruvian 'Yepezis'.. all of them came from Iquitos..
Ok, I missed a nameMiles;1297647; said:
Orbignyi is the only existing species that may have such a wide variation in coloration and distribution. But as said above I think these rays are a undescribed species so I name them P. sp. Peru.
Funny names, laticeps is a synonym for motoro, former used for the "histrix" from Rio Negro, a undescribed species (P. sp. C or P. cf. histrix).
And yepezi? ok this name for rays with such a coloration comes from the Aqualog. But yepezi is endemic to the Maracaibo region in Venezuela and look very different. Maybe the so called Maracaibo ghost is a real yepezi, who know for shure?:

(the last picture at that website show a ray from Peru that was sold as yepezi as example how different they are compared to the rays from Venezuela)
I would agree. Do you know of the specific locales that Orbignyi have been collected from? From what I understand about Motoro sp. "Peru" and it's many brown colored variants, is they are collected from a wide variety of tributaries.rayman;1297677; said:
I've noticed different exporters have different theories on Ray ID, it seems to create confusion. I researched the root of 'laticeps' and what you said is pretty much what I collected.. More undescribed variants from Peru, but should all be treated as Peruvian Motoro, No?
Orbignyi, is smaller in maximum size?
I am trying to distinguish if their are 2 different species, each with an immense amount of color pattern morphs.. Maximum size being the issue, but at the same time I am wondering if maximum size is different in every single ray due to hybridization, collection locale, environment, etc..
I have seen this 'true' yepezi link before, very interesting. Is their any solid info on why the one from Venezuela is the true yepezi, but I would believe that it is.. While the peruvian collectors needed a new name for their new Orbignyi or Peru Motoro morph, they pulled up Yepezi just like they did Laticeps..
Thanks for the feedback..
so how many rays are being considered a P peru sp??? any ray that cant be ID is considered that??? its amazing the difference a computer moniter makes on my phone that ray you posted i would have considered it a castexi varrient
