18 mm. Hua Phan, north-east Laos.
Wonderful Mesosini, but after reading all my documentation, no idea and no ID.
If someone knows it...

It's between Mesosa (Aplocnemia) latifasciata White here, 1858 and Mesosa (Perimesosa) irrorata Gressitt, 1939 here
Gérard is for the first one. Me, I don't know. But, because of "Differs from Mesosa latifasciata Matsushita of Formosa, in having the forehead higher, the vertex more deeply concave", probably Gérard is right.

Perimesosa devrait avoir une pubescence dorsale bien visible... y a-t-il?

Il reste encore les Agelasta... mais avec les nouveaux critères, ça devient difficile...

Sur la base des photos parues dans le Cahier Magellanes n° 16 (p. 135), je dirais Mesosa (Perimesosa) irrorata.

Je crois que c'est Agelasta humeralis (Gahan, 1894).
L'holotype de Mesosa (Perimesosa) irrorata ici possède des bandes noires parallèles sur le disque du pronotum.

Elle n'a evidemment rien à voir avec cette espèce.

Oui, tu as raison Francesco. Cette espèce a un habitus proche des espèces chinoises Mesosa (Perimesosa) enodata Holzschuh, 2017 et Mesosa (Perimesosa) guttigera Holzschuh, 2017, mais sans poils érigés, ce qui exclut le sous genre Mesosa (Perimesosa) Breuning, 1939.

Avec cette crête basilaire longitudinale élévée sur les élytres, une Mesosa (Metamesosa) Breuning, 1938 ?
