Identification confirmed by Nicholas Gompel, who dissected the specimen.
We are in the midst of discussing about publishing a short note on this discovery.

Do we consider it an accidental adventive and place it in Accidental adventives or do we regard it as an introduced species and list it in List of non-native arthropods?
The matter is: how likely is it of getting established? Is it already established? Is it just one specimen without a mate?

Probably established
I have collected multiple female specimens, presumably of this species at lights over the course of a month last summer. Females (with shorter antennae) are usually extremely difficult/impossible to determine to species but the overall habitus, color, etc., strongly suggests that they are conspecific with the male pictured here.


Moved base on the following note from Nicolas Gompel:
"The genus is Euglenes and this is a male specimen. Given the shape of the antennae, if it were frome Europe, I'd say E. pygmaeus. But from America, I'm not sure; a picture of the genitalia would help."

Moved from Antlike Leaf Beetles.

Thanks guys for the ID!
Looks like a new exotic species for North America.


looks a lot like some EuEu (European Euglenes)
check this

dunno what it is, but nice find anyways
Moved from Spider Beetles.

that's a new beetle family for me :)

let's buy each other a drink
really, this is something to celebrate: i see just one aderid listed for BC (none in AB!!), and this is definitely not it
