I have never seen the holotype of this species, and I do not know if Gressitt ID is right or not. |

| Xylotrechus smei seems to be a cosmopolitan invasive species, found also in Africa in Tanzania and Malawi. |

Thank you. Has X. smei invaded Europe?
I believe then that this species must be X. smei. It is very difficult to explain how it was captured in Colorado (USA) !!
However, the data is 100% correct. There has only been this one specimen so far. |

| Please have a look at BioLib. This page shows the distribution of X. smei in Asia, Europe, Africa and by the way North America. I don't know where though. |

I have not found any reference to of X. smei being previously reported from North America. Biolib has not documented their information.
The specimen was returned to the museum that loaned it to me. A lateral view will not be easy to get. |

This species was misidentified with X. stebbingi for a while. I published a rectification in this paper.

The North American datum derives from
USDA, 1996 - Importation of Fresh Mango Fruit (Mangifera indica L.) from India into the Continental United States. A Qualitative, Pathway-Initiated Pest Risk Assessment - United States Department of Agriculture, Animal and Plant Health Inspection Service, Plant Protection and Quarantine, 98 pp. Available here.

| Francesco, in the 1996 USDA paper you are quoting, Xylotrechus smei is listed as a pest associated with mango in India. Under the Follow Pathway column, it says N, which means it had not been found in the US at that time. |

Well, I corrected the gallery.
Evidently, it was a prophecy.  |
