lbb - Colon hubbardi - male

lbb - Colon hubbardi - Male
Medford, (~25 miles east of Philadelphia, PA) Burlington County, New Jersey, USA
May 23, 2011
Size: 2.1mm
these views of now relaxed beetle added to show detail of legs (my apologies for all the vignetting on this one - my 10x CFI set-up is not yet worked out for < 10x images. And the blue goo is left over from what I stuck the beetle to while speading the legs).

I believe the hind "femora toothed near apex" can be clearly seen. And it appears that "3 pro-tarsi are broadly dilated". Only problem is that those two traits are from diffent portions of couplet #1 in D&A! So I'm no further than before, but suggestions welcome :)

Moved from Colon.

i doubt D&A would do in any case; you've gotta try the revision
(1) (i don't have a copy; ask Brad?)

 
i have a photocopy, no pdf file though
I'll do a more thorough check to see what species possibilities are

 
possibilites
Based on location, and the combination of dilated front tarsomeres and a subapical tooth on the hind femur, this is definitely Colon (Myloechus) sp. Note the size of the tooth of the hind femur is very variable, with males falling into "minor" and "major" groups. Then from there, using location to eliminate a number of species...

Pronotal disk punctate, not granulate? then C. megasetosum

Pronotal disk granulate, actual punctures difficult to see? then C. hubbardi (noted as "our most common species" and "most frequently captured species of Colon at UV light traps")

The texture of the pronotum can be difficult to discern from a photo, as we have seen in other cases on BugGuide.

I would say most likely this is C. hubbardi.

 
looks perfectly granulate to me
thanks, Brad

 
your colon is granulate?
must be eating a lot of roughage...

 
=-=
the genus revision should have been submitted to An[n]als of Colonoscopy

 
these poor beetles...
always at the butt of someone's jokes...

 
*_*
i wonder if the unpretentious 'Hubbard's Colon' is okay as common name
(good thing we do not have to coin one for C. megasetosum yet)

 
we should submit that
to the ESA for approval as an official common name :)

 
megasetosum?
wouldn't that name be, 'Big Hairy Colon' ?

 
more fun Colon names
just to name a few, C. horni, C. bidentatum, C. lanceolatum, C. oblongum, C. elongatum, C. grossum, C. schwarzi, C. aedeagosum, and my favorite, C. monstrosum.

 
aedeagosum would be my top choice
the Gross one is also fine

 
horni is amusing...
'Horni' Colon...

 
nah...
that celebrated worker had too many spp. named after him, so the pun has been used ad abuseam, incl. on BG

I would guess
probably C. hubbardi, but that's still just a guess.

 
ha! as was ratting you out...
