Moved tentatively per the following Dr Dunford's comment:
"Looks to me like it could be a Haplandrus, perhaps H. ater. These Mississippi tenebs may need some attention because some of them could be county or even state records."

[another great addition, Johnny! =v=]

Moved from Darkling Beetles.

Thanks V, all 3 collected were measured at 6.8 to
7mm BL,I wonder if any are in collection at Mississippi
Entomological Museum?

more evidence
MCZ type looks very convincing
More input from Dr Dunford: "I have seen some variation (color, size, slight shape/marginal differences) in most species, especially when you compare specimens side by side over a large geographic range. Adult 'age' (=color of appendages) will also show in some cases. Also, when comparing images in books and/or on-line, keep in mind that specimens are distorted during the curation/drying process, and the angle at which images are taken will distort how narrow or wide something looks. I have never collected H. ater myself, but I would say we are close if not on with our determination."

Moved from ID Request.

collection data?
under bark? rotting log? stored grain?

Correction, I believe tree is Quercus margarettiae
or near.

Under bark of I think Gum tree but will have to
confirm,I have 3 collected.

maybe near Haplandrus? Cant find a good match on the Tenebrionidae of Eastern US site. Kinda also looks like an elongate Platydema, but they all appear to have punctures on the elytral intervals.

I looked in Platydema also and no match,pronotum
in frontal shot seems to be rounded?

and by 'hmm' i mean, HMM!

Should I add another dorsal , I though dorsal was good
but sometimes tricky?

imagery's perfect--
my brain is... hibernating... --that's the problem; i asked Jim Dunford to take a look
