My guess would be Cr. sp. Tapajos I, Red Tapajos Pikes. The pics are a bit blurry to be 100% certain but regardless... very, very nice fish!! The females do indeed have the bright white submarginal band on their dorsal.
Gonna find lugubris sp. 'atabapo' before you find sp. 'atabapo'...two different types of pikes, both of which aren't all that common.... Your LFS has to be GOOD or order from Rapps and the like if you want to see that type of pike...
