This beetle from Andasibe (Antananarivo reg., near Rogez). 36 mm.
I'm tend to Closterus extensiramis but have not any possibility to comparison..

Hello Max,
If the interval between the upper lobes of eyes is the same that the interval between the lower lobes, it is Closterus oculatus Gahan, 1890. Closterus extensiramis is brown-redish and darker on the pronotum and the base of elytra.
I've got the key of this genus and the pictures of those two species.

Yes, the interval between lower lobes of eyes narrow but obvious, about as upperside. And the formation of antennas is very similar to oculatus.
Thanks a lot, Philippe.
