J'ai regardé dans le Breuning, sans rien trouver.
Pas facile pour ces bêtes magnifiques. |

Hallo Gerard. this spec. is determined by A. Weigel as Cylindrepomus aureolineatus Dillon & Dillon, 1947, 18 mm and from Trus Madi. |

I think Gerard's one is Cylindrepomus spinosus Hüdepohl 1990.
Elytral apex has longer teeth in C. aureolineatus. |

Females have an acuminate elytral apex. Males do not.
Here is a male C. aureolineatus from Sabah (Borneo).
I have seen numerous specimens of both sexes. |

Thank you Dan. I didn't think about sexual dimorphism.
Do you think these species are synonym? |

For Titan base both species are valid and not synonym.
C. aureolineatus from Sarawak / Borneo and C. spinosus from Thailand. |

I just starting to understand something (may be I am wrong):
- Holotype of Cylindrepomus spinosus Hüdepohl, 1990 has been "collected" in "south Thailand" by Sabine Steinke. (see here)
- Other specimens come from ... Borneo like on this page
What could be the conclusion?? |

Décidément on en sort pas ! je vais finir par croire que la Thailande et Borneo étaient côte-à-côte il y a peu de temps ! |

C'est la magie de la tectonique des plaques
Ce post sur Saraburi est décidément passionnant  |

Manifestement, le post sur Saraburi ne plait pas à tout le monde.
Cependant, je ne suis pas du tout décidé à me laisser impressionner ou égarer par des approximations vaseuses. C'est même l'inverse ; l'adversité est...motivante  |

C. spinosus seems likely to be a synonym of C. aureolineatus. It is too soon to say with absolute proof.
Yokoi and I are doing another paper on Dorcaschematini planned to be published in 2018. There are some remaining new species, new subspecies, and if C. spinosus is a synonym, then we will publish it as such. Yokoi has examined nearly all of the holotypes of this tribe.
The discussion on Sariburi has certainly explained some curious patterns of distribution. |

Now I read the topic "Saraburi, XI.1988, Thailande".
Attached specimen was collected in Selangor by myself.
Inspite of Gerard's one is labeled "Cameron Highlands", this species distribute in Peninsular Malaysia at least.
