Pasimachus with prey remnants? - Scarites subterraneus

Pasimachus with prey remnants? - Scarites subterraneus
Franklin County, Missouri, USA
September 13, 2009
Size: 30 mm
Just noticed a phoretic mite on pronotum, interesting -- But actually wondering if the snail and beetle remnants behind the Pasimachus are the beetle's victims, possibly including a cannibalistic encounter?

Moved
Moved from ID Request.

 
What criteria
were used here for species designation?

 
it looks like subterraneous......
...but i don't think that you could tell for sure from this image

 
If not at least 95% sure,
then I recommend staying at the genus level.

 
Scarites - antennae segmentation + length ?
Aren't those typical characteristics needed to get down to sp.?

 
Yes in part.
Both the long body length (30 mm) and an image possibly suggesting elongated antennomeres would be traits against Scarites subterraneus in my opinion.

Scarites ?
That beetle looks like a Scarites to me vs. Pasimachus

 
definitely scarites
-

 
Agreed
Scarites

 
And its prey???
And its prey???

 
prey
Did you see it eating either item, snail or beetle? According to guide they're nocturnal predators of other insects, but it doesn't specify what. I'm not knowledgeable enough to make any kind of ID statements about the snail or beetle exoskeleton.

 
prey eaten by ants maybe
To me it looks like the other beetle got hollowed out by ants.
