Unknown Weevil

Hi Adrian,
This is some species of Weevil, though we have not been able to find a matching photo online.  Weevils are sometimes called Snout Beetles or Bill Bugs because of the shape of their heads. 

Many thanks Daniel – I had the same problem! Much appreciated anyway.

Perhaps one of our readers will eventually provide an identification.  Sometimes this even happens years later.

Weevil from Costa Rica – August 19, 2011
Hi Daniel and Adrian:
I believe it is a Straight-snouted Weevil (Brentidae) in the sub-family Brentinae (tribe Arrhenodini).  The general shape, color and pattern appear to be quite common Brentids globally, but I think I can narrow this down to one of two very closely related genera; Arrhenodes or Estenorhinus. Both have representative species in Central America but online photos are difficult to find. Based on the text description and illustrations found in the Electronica Biologia Centrali-Americana (see Figure 11), I am leaning towards E. guttata. The irregular black patches on the sides of the thorax are apparently diagnostic for the species. I can’t be certain but I believe that is getting pretty close. Regards. Karl

    i think this might be on the lines of a Metamasius nudiventris Champion which is found in coasta rica. though not everything lines up.
