Chumy,
Definitely it is not an oculata nor a gibbosa; take care when searching web sites, almost 100% are not updated about the changing names of the former impressa (now gibbosa) and the new name of the former gibbosa (now confusa). In the IOSPE when you search for gibbosa you will find
Stan confusa (
IOSPE PHOTOS).
Stan gibbosa is here (
IOSPE PHOTOS) and here (
impressa2), wrong named as "impressa" (nomen nudun)
I agree with Gwallogwyn, your Stan is probably a jenischiana (look at
jenischiana3 and forget about color or eye-spots; watch in the shape of the lip - the lip is almost identical to your Stan)
