Flea Beetle

Thanks, injica, however we still not know if this one is Omophoita cyanipennis. Personally I don't think. And there is unfortunately no Cyanipennis decemmaculata and we do not now if this would be Cyanipennis octomaculata.

you can add cyanipennis too because the full name of 8-spotted is Omophoita cyanipennis octomaculata, meaning that the name of yours would have just the third word different not octo (8) but decem (10), although I'm not sure whether it goes in Latin by the 1st regular declination adiectivum femina (Omophoita cyanipennis) decemmaculatA or masculinum decemmaculatUS.

Thanks bayucca and Keith. I didn't know you had settled on Omophoita as the correct genus, I have updated.

Some one from Alejandra:

Same one, but is the ID correct?? Most of his beetles are not IDed. I still do not think it is Cyanipennis with 10 spots. But thanks for the link!

Here's a beetle from Ecuador with a similar configuration of 10 spots.

Decemmaculata exists for beetle, but not for yours...

Thanks bayucca, Keith and Yuko. I'm not sure about the links because they only have 8 spots.

Sorry, that was the wrong link.

Hmm...Well I did check for O. cyanopennis in South America...

but I will admit to not counting spots carefully enough. :)

I would agree with Omophoita, but I am not sure if it is really Cyanipennis. Range is not clear. Bugguide only mentioned US, Central America and Caribbean, not South America. Spots look also somehow different.
There are actually 10 spots! ;-)...
Another genus? Disonycha?

Such a lovely beetle!
