Let me come back with this post. I hold this beetle in hands now, and it is really a particular thing. The strange structure of the pronotum is due to wet hairs on Hexapoda's photo.
Francesco, congratulations to the new forum, looks nice! The species illustrated here looks like Aegosoma annamensis. Fluffy hairs...In case somebody is interested in photos of further specimens and the description, please write me a PM. Robert
According to Komiya, Z. & A. Drumont, 2012. Description of a New Genus Close to Aegosoma (Coleoptera, Cerambycidae, Prioninae), (Revisional Studies of the Genus Megopis sensu Lameere, 1909-11), Elytra, Tokyo, New Series, 2(2): 181-187, it is Metaegosoma annamensis (Pic, 1930).
Just a little up on this topic to confirm the taxonomie of the right specimen from Pia Oac. It's definitly a female of Metaegosoma annamensis.
240.57 KB As you can see on the picture above, the female of A. katsurai (left) features shorter antenae, the pronotal shape is clearly different and a longitudinal sutural costae is present on elytrae of annamensis (does'nt exist on katsurai elytrae). Space between eyes is wider on annamensis. In addition, I don't see any groove on third antenal segment of the right specimen.
Vietnam: Metaegosoma annamense ♂
