What makes this species remarkable?
The animal can be more than ten times longer than it is wide, pushing the weevil body plan towards the proportions of a needle rather than a conventional beetle.
Its rostrum continues the same straight axis as the head and body, creating a continuous spear-like profile instead of the downward-curved snout seen in most familiar weevils.
The narrow geometry is itself camouflage: aligned along a twig or leaf midrib, the insect suppresses nearly every transverse edge a predator could use to recognise it.
