Entomology (Study of Bugs)/What is it?


I photographed this bug in Ecuador - east side at say 500 m.
The 2 huge legs and large size make it unusual.
Any ideas would be appreciated.
Link to photo:

Dear Les - As you already know, this is a leaf-footed bug (Hemiptera/Heteroptera: Coreidae). My best guess is that it could be in the genus Acanthocephala - see http://tinyurl.com/bp6p7ne for an example. Some of these are truly impressive, with a body length of 50mm or so.
Hope this helps,

Unfortunately, there appears to be little detailed information available on the species that occur in Ecuador and adjacent areas. If you search for images, you usually will find no information other than the date, location, and identity of the photographer. Very occasionally, if you're lucky, you may find that someone has commented on a possible i.d. on Flickr...

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
