In September 2011, I photographed a long-horned beetle, which has been recently identified by Everardo Grossi, a friend of Isabel Miller.
According to Everardo the species is Hypsioma inornata (Hypselomus inornata).
There is a specimen in the Paris National Museum, labelled simply “Brazil”.
I have little familiarity with Neotropical Cerambycidae. Perhaps there are more recent records in recent entomological literature.
