Wedge-shaped Beetle - Macrosiagon cruenta

Macrosiagon cruenta, female

This one is easy- Macrosiagon cruenta (Germar 1824), a female. It's one of the most widespread Macrosiagon species in the U.S. and probably the second most encountered after Macrosiagon limbata . There are several named color variants ranging from all black to nearly all reddish yellow, but I believe they are not really worthy of subspecific status.

My first post- I apologize in advance for any faux pas.

No faux pas, thanks!

Well, thanks very much. I see you are an expert on this family. We'd all sure appreciate double-checking of such work as has been done here on the family already. Some of it has been done by me--I'm a dangerous amateur, armed with a couple of references and an urge to classify.

Again, we all much appreciate your expertise, and look forward to your contributions in the future.

Patrick- Thanks for the we

Patrick-

Thanks for the welcome. I'm still getting used to cruising around the site, but what I've seen so far has been pretty neat. I'll see if I can't add some more determinations/data to the rip section in the next few days... I might throw my two cents in in other sections as well...

cheers,

zack
