Beetle - Holoparamecus pacificus Beetle - Holoparamecus pacificus

Moved from Holoparamecus.

Holoparamecus pacificus
It's tough to be sure from the pictures, but it looks a lot like Holoparamecus pacificus. Could be one of the Mexican species though. To be honest, no one has really looked extensively for merophysiines in the southwest. Awesome pic though!!!

thanks, man.
we'll call it that for the time being. they seem rather elusive, at least in the wild -- i can't remember ever finding more than one in one spot... well, maybe once in a moldy grain overrun by Aglenus brunneus, Cryptophagus, Tenebroides mauritanicus, Alphitophagus bifasciatus, Palorus spp., some anthicids, et je ne sais quoi...

Thanks v and Floyd.

I've collected Holoparamecus under bark of dead Populus in the Sunflower area, not too far from where this specimen was found.

must be it...
i'll ask around re: species ID (Floyd, Charlene, Rick...)

Moved from Water, Rove, Scarab, Longhorn, Leaf and Snout Beetles.


Wow. How so fast? Do you have the Harvard types memorized?

I didn't have a very good idea on this one. I will check tarsal formula and try to key it this weekend.

i am a @#$% harvard type

Haha! You're one-of-a-kind! Known only from the holotype. ;-)

mislabeled, too
may turn out nomen nudum one day
