What's That Bug?

One of our difficulties with Nature Study on this part of the planet is, identification.  There is some serious diversity here in Peru! (and I'm not complaining!) It was said by Theodore Parker III, famous American field ornithologist, “Peru offers ‘bird-enthusiasts’ more than any other country in the world… Being here is like being a child visiting a huge store filled with new and fascinating toys”.  While the resources are vast for identification of wildlife native to North America, I have yet to find any comprehensive online resources for South America.  Lots of animals, birds and insects are similar but with variations, so it is difficult to nail any one specimen down, even with the best of sources.  So while we do have a couple of books as helps, I still many times am at a total loss.

Today for example, after several hours spent on Whatsthatbug.com looking to pinpoint several of our local bugs found on recent nature walks, this one stumped me, so I decided to submit a question.  Here it is:

My son spotted this bug while we were out on a nature walk.  It is a bright blue.  While I've spent several hours searching your site for something similar, all I've found is the masked hunter (but I doubt it is this because there was absolutely nothing this color anywhere near where we were... no blue carpet :).  It is similar in color to the blue-green citrus weevil, but it's body doesn't look like it as it's rather bumpy.  Just thought it'd be fun to identify it, though I didn't imagine it would be this hard... :)


He was about 2cm in length and was crossing a dirt road near a farm of coconut trees.  We live in 'ceja de selva' (which is on the eastern slopes of the Andes, above true rainforest level).

Any ideas?

All I know is, that it's possible that I've found a species that hasn't been discovered... and I want to name it if that is the case!  The Turquoise Blue Tuttle Beetle.  of course.

My Recommended Resources:
While we're on the subject of identification guides, here are the books we have:
(only one is specific to Peru, or South America for that matter)

Here are the books we'd like to have... someday: (why on earth are they so expensive?!)
