This species is very variable, as the 19 pictures at NUDIPIXEL are demonstrating.
Let me quote Marcela Bolanos at LifeDesks:
"The diagnostic character for this species is the black background with large and irregular yellow-green maculae and an orange marginal band."
This specimen posted at these websites as a strange variant of Pseudoceros scriptus is most probably a variant of
Pseudoceros scintillatus Newman & Cannon, 1994.
