It's succinctus subspecies. What colour on metasternum: black to dark brown, or red? |

But seeing the elytral marking, and the profile of prosternum - mesosternum, I would say T. succinctus succinctus (L.) |

Trachyderes succincta (Linné, 1758) pour le nom complet. |

Je reprends la terminologie de Titan, mais si quelqu'un peut nous éclairer sur le genre du nom Trachyderes... |

L'intention n'est nullement de polémiquer; mais bon, pour autant que je sache, seul Titan utilise la forme féminine pour toutes les espèces de Trachyderes avec la terminaison -us. Aucune autre base de données (Biolib ou autres) ni source littéraire (révision, catalogues) que je connaisse n'en fait mention ne serait-ce que en tant que synonyme. Oui, ce serait intéressant de connaître l'argumentation qui mène à cette terminologie.

Bonjour, si je suis l'etymologie de Trachyderes toujours donnée par Titan, cela signifie "cou rugueux" donc on pourrait le classer au masculin ... |
