"its either a different form of the palmas buettikoferi from a different population/locale or palmas palmas (unfortunately i can't really narrow it down one way or the other due to confusion over what exactly does a palmas palmas look like)"
in any case it should be part of the palmas complex
definitely not a retro,
like PST said, its probably a variant of palmas buettikoferi, or a palmas palmas. Sort of looks like PSTs palmas palmas, but with more defined stripes
