Colydii*dae ? (no, Monotomidae) - Rhizophagus dimidiatus

Colydii*dae ? (no, Monotomidae) - Rhizophagus dimidiatus
Jefferson Notch area, Coos County, New Hampshire, USA
May 12, 2007
Size: about 3.5 mm
I found a pair each of two species of slender little underbark beetles with very compact antennal clubs. This is the larger and more elongate of the two, and more handsome in my opinion due to the dark red humeral and apical markings of the elytra. They were right in there with the sa*p beetles on a couple of still-weeping stumps, one coniferous and one deciduous.

Since the markings are definitely different from R. say*i,
I conclude this is R. dimidiatus, the other orange-marked Rhizophagus. Moved from Rhizophagus.

R. dimidiatus ?
The red shoulder point Rhizophagus dimidiatus I think : or they are an other species with this color patern in NH ?

 
Dimidiatus
but probably not sayi there are two species with orange marks on dark elytra.

 
I've got three for you, Don.
I had stuck one in with some other specimens.

 
Dimidiatus
is likely, but with sayi around I would prefer to check out the punctations.

Moved

Well, this seems to be a new family for my personal list.
Moved from Beetles.

Bothrideridae is my guess on
Bothrideridae is my guess on this one too.

 
None in New Hampshire.
How about Monotomidae? There are nine NH species in that family and their antennal clubs look like a match.

 
Rhizophagus sp.
A different one. Save also.

 
I'll save both spp. for you.
Thanks, Don.

 
Of course,
and thanks.

 
Agreed, I forgot to check tha
Agreed, I forgot to check that family... Rhizophagus perhaps? I can't see enough detail of the procoxae/antennal grooves to be 100%, it'd key to Phyconomus otherwise
