Somebody had seen or know about a Carabidae (Coleoptera) with a large femoral tooth, in the anterior femur and in the middle of lenght? Some days ago i found one individual very rare in South America and i`m confused. Thank you for your help.
Can you post a photo? That would help a lot in identification, also the locality would help, "South America" is rather vague.
Please see collector-secret.proboards.com/thread/11/attach-picture for how to put a photo or several in a post. Note the attachment option is no longer available, you must post a link to a photo that is already online. I recommend imgur.com, it is free and easy to use once you get used to it.
Closest I see on Bing (not a good reference) is Harpalus sp? However. A specimen with a large femoral tooth may be a variation or subspecies of the group.The University of California site couldn't firmly establish their harpalus sp.it had the ? at end of Id.Alot of variation in these beetles.a fascinating group to study.
