Having in mind to publish a revision of a genus belonging to this tribe, does anybody know on what publication this new split is based?
I thought on Sama (2008), but this author synonymised Lamiini with Phrissomini (in my opinion, partially correctly) and with Dorcadiini (in my opinion, incorrectly). "Monochamini" were not mentioned either. |

I have not found this paper either; nonetheless, the first mentioning both tribe is Lacordaire (1869b).
(p. 288)
Section A - Métasternum très-court, au maximum et rarement médiocre. Front rectangulaire, jamais rétréci en haut; tubercules antennifères divergents. Yeux plus ou moins fortement granulés, leurs lobes inférieurs médiocres, étroits et obliques. Prothorax jamais inerme latéralement. Corps très-souvent aptère, avec les élytres soudées. ... Phrissomini and Lamiini
(p. 298)
Section B - Métastemum plus ou moins allongé, jamais très-court. Front tantôt rectangulaire, tantôt peu à peu rétréci en haut, par suite trapéziforme. Elytres jamais soudées. Corps ailé. ... Monochamini
I hope that nobody thinks that Lamia is wingless... 
Since it is winged and it flies as Monochamus!

This revision dates back 1997... but a worldwide study still existed! It has already been published by Breuning in 1943-44.
Monochamini was also used by Dillon & Dillon.
In the library, their first paper dates back 1959, but it is still the fifth part and it does not contain explications. However, we are not far from 1944.
Monochamini was mentioned in many articles before 1944 (in reverse chronology):
Gressitt 1940. The Longicorn Beetles Of Hainan Island.
Matsushita 1933. Beitrag zur Kenntnis der Cerambyciden des Japanischen Reichs.
Plavilstshikov 24 1925. Russkije widy Monochamus. „Monochamini sensu Lacordaire 1869”
Lacordaire 1869b. Histoire…: p.240 mentioned „Longicornia Malayana” Pascoe
Pascoe 1864-69. Longicornia Malayana p.8:
"Monochaminae. Caput exsertum. Pectus antice plus minusve elongatum. Antennae approximatae. Scapus elongatus, cylindricus,apice cicatricosus. Prothorax lateraliter inermis. Pedes elongati, femoribus simplicibus. Mesosternum declivum."
Oldest article should be Gistel (1848) but I havn't it.
"Monochamini" species was difficult to determination to tribus level if Monochamini exist. I am glad from good news about very interesting article Souza et al. 2020. |

Très bien, observation et logique restent forces de loi (scientifique bien sur !). |

According to a modern molecular phylogenetic assessment of the Lamiinae (Souza, Marinoni, Monné & Gómez-Turita, 2020, available here), it resulted that Monochamini and Lamiini belong to the same tribe, which includes Gnomini and Rhodopinini, as we supposed for a long time (see above).
I hope that this last paper closes this too long and senseless diatribe and that authors uses finally the correct taxonomy. |

Tout à fait.
In my opinion, Lamiini are a large tribe, such as Trachyderini, which should also include some tribes, such as Batocerini and Gnomini, which show neither consistent not constant differences with other genera.
In this tribe, some groups can be recognised: Gnomini (for their elongated prothorax, but not all, e.g. Imantocera), Batocerini for their open procoxae (but this character is also present in other Lamiini, such as Eutaenia, Polytretus), Phrissomini for their wingless condition (but closely related to Lamia), Agniini for their trapezoidal head (evident synonym of Acridocephalini), etc.
Monochamini and Lamiini are so closely related that considering them as two tribes is surreptitious. See for example Epicedia and Leprodera (evidently related to Lamia) and Paraleprodera (more related to Monochamus). |

Bonjour Francesco,
Pour abonder dans ce sens, j'ai examiné plus d'une cinquantaine de specimens à la loupe binoculaire en commençant par des specimens du genre type de la pseudotribu des Monochamini "Monochamus" et des Lamiini comme Lamia et Lamiomimus; puis des specimens divers comme Morimus, Epepeotes, Cereopsius, Aristobia, etc..
Après examen minutieux des bourelets cicatriciels des scapes, de l'angle des crochets des tarses, des cavités cotyloides médianes (avec quelques variation sur le degré d'ouverture) et autres caractères secondaires, je n'ai pas pu mettre en évidence une quelconque logique de différenciation.
Pour moi, je ne vois pas l'intérêt de ce "déclassement" de Lamiini. |

Maybe, but it is inadmissible using Monochamini now. |

I'm Ok Francesco, Arctolamia (and several other species) features the same dent on mesotibia.

At the end, your first question is still open... |

This explication has no sense either since both genera have two hooks (= claws?). |

Interesting, Claude. Etymology does not interest many people but can explain lots of things...!
Sigmund Schenklin: Erklärung der wissenschaftlichen Käfernamen aus Reitters Fauna Germanica (Lutz Verlag, Stuttgart, 1917):
Monochamus : gr. monos = singular, unique; gr. chamos = (fish-)hook |

The original name was Mono-hammus, where "mono" is, rightly, "one" and "hammos" means "node" in Old Greek.
Nonetheless, this explication is no good.
If you compare the mesoibia of Lamia textor and Monochamus sutor (both species-types of the genus) you cannot observe differences:
 
Lamia and Monochamus, mesotibia |

Perhaps, the answer could comes from the etymologia of "Mono"(only one) and chame or chamus (I don't find any latin definition for this).
This is probably the main caracteristic which separate this tribe from Lamiini .. (Monochamini features a "bump" on median legs). |

The difference Anaglyptini / Clytini is a bit different: the shape of the metepimera is a real character.... which can be considerer more or less important (this is the question).
But, what character differentiates Lamiini from Monochamini? |

Posted - 12/03/2015 : 17:49:45
Linsley and Chemsak mentioned that they were aware of Breuning's work, but I think they must have considered it to be inadequate in terms of generic analysis.
Nobody is questioning the closeness of Lamia and Monochamus. It's much the same as with Anaglyptus and Clytus.
Is it one tribe, a tribe with two sub-tribes, or two tribes? Higher classification can be very arbitrary.
I don't have a preference, I just don't like the classification changing every few years. |
