Eumolpinae > Brachypnoea puncticollis ? - Colaspis favosa-complex

Rhabdopterus

The dark colour, smooth lateral margin of the pronotum, slender antenna and somewhat bowed middle tibia make me think this is a Rhabdopterus species. Colaspis have toothed margins of the pronotum. I don´t see that on your beetle. Brachyphnoea have shorter somewhat clubbed antenna and are more robust.

Have you

considered Colaspis pseudofavosa?

C. pseudofavosa

Thanks for the reply Mike; to answer your question, yes I did. Even
though you told me that it is the only Colas*pis in FL that has the
shiny metallic brown color, I know that the color is not written in
stone. I still went with B. puncticollis because of the sharper angle
on the pronotum. All five of my pseudofavosa's have a rounded shape
to the side of the pronotum, and have the shiny metallic brown
finish. Does that help??? Bruce

i couldn't be more sympathetic...

those eumolpines include a lot of forms that look "is between" something and something else and drive me crazy! e.g.,

looks very similar to your beetle. i hope that some day a chrysomelid specialist will bless BG by bringing his/her expertise to this site and dispelling doubts about these beetles' identity

Leaf Beetles

V: Thanks for the reply as usual. I agree. I am ordering a couple
of publications that I found on the internet, looking for usable keys
and other info on them. Another problem with them is insufficient
comparable photo's of all the species. It would be nice to have a
site similar to the FL Teneb Checklist for the Chrysomelids eh!

… Bruce Getty, 12 August, 2009 - 1:29pm

I hope

that one of the publications you ordered is "The Leaf Beetles of Alabama." The nomenclature is out of date and it's short on illustrations but it has extensive keys that cover most of the Florida fauna.

I posted too quickly

"The Leaf Beetles of Alabama" is available online here.
