Spider-Weevil (Arachnobas sp) from W-Papua (by gbohne on Flickr)
Arachnobas is a Genus of weevils peculiar to the Moluccas and New Guinea.
When caught by an animal (e.g. me), immediately this beetle turned to lay on the back and moved its legs like a spider;probably mimicry.
Arachnobas sp. [Rhynchodes sp., is the synonym],
