Maybe this species is already on the forum but I don't find any relevant report
from Malaysia 30/31 mm (2 specimens for colour variation)

Ok, finaly I think that Gérard and Dan are right.
On C. stolzi, elytra are regularly punctuated on all the length, while C. ritsemai features punctuation on roughly 2/3 of the length end is granulated on the apex.
The specimens shown are C.ritsemai.

The species shown here compares favorably to Loxotropides brunnea Fisher (type locality = Sabah) , which has been considered a synonym of Cerosterna stolzi (type locality = Sumatra ). If true, then the photos of the two specimens above are not C. stolzi, in my opinion.

Merci Gérard et Jean-Philippe,
Avec le genre, par comparaison avec les photos du site "Lamiaires du monde", je pense avoir un ex. de C. Stolzi à gauche et un Ritsemai à droite.

Me semble plus proche Cerosterna stolzi (Ritsema, 1911) par l'apex des élytres,
MAIS j'ai un gros doute avec la forte et large ponctuation des élytres.
En tout cas, c'est une espèce de Cerosterna.

Bonjour
Peut être Celosterna ritsemai Heller, 1907 ?
