I took this picture in Costa Rica in December. I have looked in vain for an ID for this beetle. Can you help? Thank you very much for looking at this!

Dear Trudy,
Your truly impressive beetle is a Longicorn or Longhorned Borer Beetle in the family Cerambycidae, and because of its resemblance to the Ivory Marked Beetle,
Eburia quadrigeminata, which is pictured on BugGuide, we suspect it may be in the same genus.  Since we must dash off this morning, perhaps one of our readers will be able to provide us with a species identification.

Update:  We returned back to the office and we are very confident that this is Eburodacrys triocellata, a member of the same tribe Eburiini, as the Ivory Marked Beetle, and which we identified on the New World Cerambycidae Catalog.

Hello Daniel and Trudy:
Your longicorn is very closely related to Eburia quadrigeminata, but the species is probably Eburodacrys triocellata (formerly E. mexicana).  Here is another link to a specimen photographed in Honduras. Regards, Karl
