Sulawesi, 15 mm.
Is it Tmesisternus wallacei (Pascoe, 1858) female? Tmesisternus fulgens Breuning 1939?

All specimens here have a tooth a side of the pronotum. Is it really the same species ?

Andreas, do you have a picture of a true couple of Tmesisternus fulgens Breuning, 1939 ? I don't really understand what this species is like.

I don't see difference between male and femelle, that's why I ask you a picture (not this one that I know).

Both sexes are quite similar from above (female: antennae quite a bit shorter + body something wider, this features are not remarkable, at least at my few spms), the females only have a flat longitudinal furrow at in the middle of the last sternite like in all Tmesisternus.
