Cosmisoma chalybeipenne Longicorn from Brazil

Hi Henryk,
All we can say for certain is that this is a Longicorn or Longhorned Borer Beetle in the family Cerambycidae. Sadly, there are not many websites devoted to the identification of Brazilian Beetles.

Hello Bugman:
The Museo Nacional Rio de Janeiro has an excellent online searchable database of Cerambycidae Holotypes . If you go to their site and enter the Genus name Cosmisoma you will get a list of species. All of the Cosmisoma species are characterized by the curious tufted antennae. I believe C. chalybeipenne is your longicorn beetle. Regards.

Karl
