There are only 2 Caligos with a white stripe: Atreus and Uranus. Geographical range is somehow overlapping, so Uranus is more the northern one and Atreus the southern one. However, the range is not always reliable, i. e. not being found means not automatically not present. In my eyes I can see only one black spot at the apex in Atreus, whereas all Uranus I have seen have 2 black spots there. So I think yours is Atreus. If you have any shot from the dorsal side it is much easier to separate these two.
