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

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. |

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