Non, je ne lui ai pas coupé le bout des élytres. Original non ?

Yes Dan you are right, I think its T. angularis but the surface of the spm is a bit adhered.

Merci Dryobius. Cette espèce à déjà été confirmée par Francesco sur un post de Gérard :

L'affaire est résolue !

My apologies for a mistake....

After closer examination of this photograph, I am certain this is not Thylactus sumatrensis. The reason is that the specimen is too short, and the elytra have a definite post-median dark area. This is therefore (probably) Thylactus angularis Pascoe.

I have T. sumatrensis from Sumatra and Borneo and both specimens are over 35mm. They are wholly dark, almost brownish purple. The apex of the elytra are slightly different, too.

I would like to ask Xaurus to confirm this, as I believe he has T. angularis from Thailand. T. angularis is a widespread species occuring from Borneo to Thailand, so it likely occurs in Sumatra, too.

Et bien merci dryobius, encore un mystère de résolu !

Thylactus sumatrensis Hüdepohl, 1987 (they attain lengths up to 35 mm). Occurs in Borneo, too.

Magnifique ! Extraordinaire !
Une Sthenias sans doute ?
