| Coming back to this topic, the specimen at left is Ioesse rubra (Pic, 1925) and that at right Ioesse sanguinolenta. |

Taking into account the swelling at apical antennal segments 3-6, both look like sanguinolenta...
What makes you think the left specimen is rubra, Francesco? |

| I observed the different shape of the black spots at both sides of the scutellum. |

I guess physical characteristics should prevail over color differences. This being said, maybe the distribution map of the genus can help:

This map is from OHBAYASHI & LIN, 2012: A review of the Asian genera of the Petrognathini, with description of a New Species and proposal of a new Synonym.
According to that paper, sanguinolenta seems to be restricted to the Malaysian Peninsula. Where are your specimens from, Gyula? |

Je suis d'accord avec toi que les caractères physiques devraient avoir la prévalence sur ceux de la couleur, mais dans ce cas je ne vois presque pas de regonflement antennaire dans l'exemplaire à gauche.
Il serait le second cas (sur deux) que la tache scutellaire ne concorde pas avec les antennes...
P.s. Ces exemplaires ne sont pas de Gyula, mais de Cristian, qui nous avait écrit qu'ils étaient sans localité. |

Je rajoute cette bête qui est I. sanguinolenta selon la carte.
Pas spécialement de renflement. |
