Hello Martin, Nadine Kriska showed me this unknown Melolonthinae from Peru, and I am pretty sure this is the Macrodactylini Ceratolontha, which is only known from the type C. venezuelae Arrow 1948. I can not see the head, but are the "horns" from the clypeus? My look at them is from the type, female never described, strange to see this in the Macrodactylini. If this is Ceratolontha I would love to take a look, it is one of those rarely seen members, never have I encountered this in any collection! The specimen I used to redescribed this was a female, and she had short horns, so maybe this is different in terms of species.

I think it is probably a Melolonthinae (Macrodactylini). I would really like to know if anyone has an idea which genus (or species) this is. Look like the second specimen on the left might be a female (no horns). The data is: Peru, Pasco reg., Oxapampa prov., Puerto Bermudez dist., 10.4133S 074.9947W h=860 m. Many thanks for your help, Martin?
