yes, you are right! This exemplar is extremely colourful, but it is, most probably, Agonopterix conterminella. However, it usually has fainter head and mesothorax. Comparing of the coloration of these parts and forewings' bases can also help to choose between two species, in addition to palpae. A. conterminella usually have uniformly coloured head, mesothorax and bases, what reminds other Agonopterix. A. liturosa has much brighter head and mesothorax comparing with forewings' bases, which more reminds certain species from the genus Depressaria. Any other alike species are absent in our region.
Thanks again for your attentiveness,
