15 mm, Hua Phan, nord Laos.
En croisant la description de Pic (1922) et la clé de Gressitt (1970), j'arrive à Thranius granulatus Pic, 1922.

Sinon, je pense aussi qu'il s'agit bien de Thranius granulatus Pic, 1922.

Dans le livre de Wiegel, Lin &Al., cette espèce est déterminée comme Thranius simplex Gahan, 1894

Selon la description (ici, p. 15) les antennes de simplex sont ferrugineuses avec les articles 8 et 9 testacées.
Je ne crois pas que simplex et granulatus sont deux espèces ainsi différentes...

" les antennes de simplex sont ferrugineuses avec les articles 8 et 9 testacées."


mais justement, c'est bien le cas Francesco ! Je viens juste de le remarquer : les segments 8 et 9 sont plus clairs que les autres.
...On en revient donc à Thranius simplex pour moi

I do not know. Simplex should have simple elytra but this has granules like granulatus, no?
