I have this species from Sabah as well, which I believe is T. angularis. It matches a specimen which I have from Thailand that was identified by Andreas W.
I will send the article of Franz (1954) when I receive it.
It would be totally impossible to use Breuning's paper from 1950 on Xylorhizini! There have been at least 6 Asian species described since then. I believe I have 2 to 4 undescribed species from Sabah. It therefore seems very likely that other collectors and museums have more undescribed species.
