I think this is Longitarsus.
I think this is Longitarsus. This photo appears to show the elongated first tarsal segment distinctive for the genus.

 
another?
thanks John, unfortunately I currently am unable to locate this specimen to confirm under scope or re-image using my improved set-up. However, I collected another slightly darker flea beetle on the same day, which appear to have similar tarsi (protarsi #1 anyway). Could you offer an opinion on that one too? This one I do believe I have located.
Thanks,

 
The first tarsal segment is t
The first tarsal segment is too short in this specimen to be Longitarsus. This is likely a Phyllotretta.

 
thank you both,
I've added a couple of "improved" images, and some comments on genus suggestions. Please feel free to comment again on those new images.

 
reply: sp. on linked image and this one
Dear Tim,

the one linked can´t be a Longi*tarsus, because it has seriate punctures on elytra.
Nontheless that one and the one here may be the same; I overlooked images are really out-of-focus, so the nature of elytral puncturation is not detectable.
The length of the 1st hind tarsal segment is a borderline case, it seems. In Longi*tarsus, this segment equals or is longer than half of the hind tibia, it seems to be slightly shorter in this beetle.

Maybe . . .
. . . one of the species of Aphthona imported for biocontrol of spurges?
