Dear Claudia,
We believe we have identified your Longicorn as Trachyderes succinctus thanks to images on iNaturalist and Cerambycoidea. According to iNaturalist: “This species is present in Argentina, Bolivia, Brasil, Costa Rica, Panama, Colombia, Ecuador, Nicaragus, Paraguay, Peru, Venezuela, Suriname, French Guiana, Brazil, Bolivia and Antilles.”
Update: Thanks to an update from Cesar Crash, we believe Trachyderes hermani which is pictured on the New World Cerambycidae Catalog is a better species identification.
Hi,
The Colombian subspecies of T. succintus seems to be T. succintus succintus and, despite they are polymorfic, it seems that they always have striped antennae: https://apps2.cdfa.ca.gov/publicApps/plant/bycidDB/wdetails.asp?id=6652&w=n
Thys is why I guess T. hermani and T. politus are better options:

Coleoptera Neotropical is a wonderful site to check Latin/South American Fauna:

Thanks for the correction Cesar. Your input is always greatly appreciated.
