Enoclerus Checkered Beetle

Thanks, Jonathan! I suggest that you also add the term (group) in the scientific name. That would indicate the complexity of these beetles.

Thanks I will do it now...

Please, update, thanks!

¡Con mucho gusto! In the meanwhile I got a confirmation of Enoclerus crabronarius (group) by Jacques Rifkind with assistance of Jack Longino! That's why I changed my suggestion. I already guessed it might be one of the Crabronarius group ;-)...

Gracias Bayucca

Cleridae, Clerinae, Enoclerus sp.
I am pretty sure that this one is a Checkered Beetle. I first searched for Mutillidae or Velvet Ants, but looking closer to yours and not finding a reasonable match (actually first not finding a match and then looking closer to be honest ;-)...) there are differences in body proportions and anatomical structures which let me more think of a beetle than wasp. But anyway it is a perfect velvet ant mimic (or viceversa)!
Unfortunately I am not experienced enough and not at all qualified to get down to species level. My shy guesses are Enoclerus hespenheidei or some of the Enoclerus crabronarius group. I try to get closer...
