Beautiful... unfortunately, I did not see it before the publication of my revision. It is Acalolepta keyensis, subspecies of Acalolepta... you have to wait for the next number of Les Cahiers Magellanes!
The name of this species is officially Acalolepta longicornis keyensis (Breuninm, 1965).
The revision of this group The Acalolepta australis species-group, with revalidation of Dihammus Thomson, 1864 as a subgenus (Coleoptera, Cerambycidae). Les Cahiers Magellanes 31 can be requested here.
