I agree with the genus, but I can't find any species that resembles it. Maybe Hippocephala collardi Gouverneur, 2021 but I see some differences... What do you think Xavier? May be new species? Saludos Sergio
Comparing the photos with H.collardi, it seems to me that the pronotum of your species is shorter; the forehead is more punctate, with more widely spaced carinae; the lower lobes of the eyes are larger.
