September 2004. This beetle was photographed in the forests of Guyana. It is about and inch and a half from head to abdomen, giving it a cylindrical shape pale brown elytra and darker thorax and head. The antennae are longer than the body with about 10 or so segments which elongate towards the tip. The lower abdomen is also pale brown and the head has sharp cutting mandibles. It was attracted to light.

Samoa thught it might be a Dihamus spp., but this was discounted by other members. The size and colour suggest that it belongs to the subfamily Prioninae. The definitive character for this subfamily is that there is a lateral carina on the pronotum which is always present, but may be incomplete and not run the full length of the pronotum. It is not clear if it is present from the photos.

The subfamily Lamiinae contains several large species. This subfamily usually has the head with the mouthparts directed ventrally rather than directed anteriorly. It is unclear from the photos.
