When I compare this to my previous Olbonoma Triptycha sighting ( Olbonoma triptycha (Concealer moth) on 22 Nov 2019 ) it looks really similar except for the dark patch in the wing and fewer light sections in the legs.
Common placed Olbonoma and Isomoralla in totally separate groups based on microscopic examination of the genitalia. Trying to decide on specific names based purely on superficial wing patterns is basically flawed, especially bearing in mind that about half the Oecophorinae illustrated in the BOLD pages are unnamed. I think the best we can do when we get contradictory indications like we have here is to identify the specimens as Oecophorinae sp.
I think Marthijn got it right at the start. O. triptycha sometimes comes without the central band (see 3401787), and the image matches O. triptycha well.
