SInce it's sub-adult coloration, won't the laminate fade just as we have seen happen in juvenile C. sp Venezuela?
From what I have seen, the red shade appears in X2 subadults and these species are similar to C. dandara and C. percna as they are prognathus and have compressed heads. Subadults also have an ocellate caudal spot. As they reach adulthood, the ocellate caudal spot turns very big and black. Their heads become more and more compressed as they mature and they also develop a black blotch on their humerus as they become adults. Because of their distinct subadult coloration, I suspect that X2 are one of the lugubris pikes that do not have the juvenile coloration characteristic to the members of the lugubris-strigata group, meaning they don't really have the black and red laminate trait.
