I have both types pictures of Schmidtiana violaceothoracica (Gressitt & Rondon, 1970) and Schmidtiana testaceicornis (Pic, 1926) and I am still unable to see diferences between them.
How do you do for separating the two species ? |

En fait Xavier, je ne fais pas de différence, comme nous l'avions déjà observé sur ce topic.
Tant que la synonymie n'est pas officialisée, je pense que l'un ou l'autre des 2 noms est juste. |

| D'accord comme ça, mais si le nom de Pic devrait gagner la course à la priorité historique... |

I think there are other species of Schmidtiana which should be synonymized, too, or lowered to level of subspecies (despite all the recent papers on Schmidtiana).
For example, I have been confused about S. borneoensis and ochracea because the black markings on the elytra are the only differences I see.
Does anybody have the time to study genitalia? |

... des 3 noms...
It is interesting to notice that Karube described from southern Vietnam another Schmidtiana having a pattern apparently identical to these species: Schmidtiana shinkaii Karube, 1998.
Description here. |

Hello Dan. I check also the genital morphology of Schmidtiana, but is a great problem and not in three weeks cleared.
Another problem is to receive enough material. Especially from Borneo I have few material from all genera of Callichromatini.
In this time, I have checked the HT of S. borneensis Podany, 1968, I will add the picture in the Type section in the next time.
To S. testaceicornis / violaceothoracica:
I have checked many spec. of them and the variability of the spines of the pronotum is very great in males, also inside a series from the same locality. There are spec. with great spines and spec. without spines. In one specimen left side is with a small but distinct spine.... the other side without spine !!! Also the width of the yellowish part of the elytra is more or less variable.
S. shinkaii.... hmmmm ???.... the aedeagus is different, but in one specimen  ???
The other differential features are more ore less vague  |

I think Bill`s specimen is S. testaceicornis and violaceothoracica is a synonym.
The description of new species of Schmidtiana and several other genera of Callichromatini (Chloridolum, Chelidonium, Polyzonus, Aphrodisium etc.) is in my opinion at the moment very careless  |

| As supposed, both species were synonymised in Bentanachs & Jiroux (2009). |
